General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are
used as test pins or to reduce noise. If something is connected to the NC pins, the
operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins
are in their open states, intermediate levels are induced by noise in the vicinity, a pass-
through current flows internally, and a malfunction may occur.
3. Processing before Initialization
Note: When power is first supplied, the product's state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the
chip and a low level is input on the reset pin. During the period where the states are
undefined, the register settings and the output state of each pin are also undefined. Design
your system so that it does not malfunction because of processing while it is in this
undefined state. For those products which have a reset function, reset the LSI immediately
after the power supply has been turned on.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers
may have been be allocated to these addresses. Do not access these registers; the system's
operation is not guaranteed if they are accessed.

Preface
This LSI is an RISC (Reduced Instruction Set Computer) microcomputer which includes a
Renesas Technology-original RISC CPU as its core, and the peripheral functions required to
configure a system.
Target Users: This manual was written for users who will be using this LSI in the design of
application systems. Target users are expected to understand the fundamentals of
electrical circuits, logical circuits, and microcomputers.
Objective: This manual was written to explain the hardware functions and electrical
characteristics of this LSI to the target users.
Refer to the SH-2A, SH2A-FPU Software Manual for a detailed description of the
instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
Read the manual according to the contents. This manual can be roughly categorized into parts
on the CPU, system control functions, peripheral functions and electrical characteristics.
• In order to understand the details of the CPU's functions
Read the SH-2A, SH2A-FPU Software Manual.
• In order to understand the details of a register when its name is known
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 26,
List of Registers.
Rev. 3.00 Mar. 04, 2009 Page vi of xxiv
REJ09B0344-0300
• Examples
The notation used for register names, bit names, numbers, and symbols in this manual is
described below.
CMCSR indicates compare match generation, enables or disables interrupts, and selects the counter
input clock.Generation of a WDTOVF signal or interrupt initializes the TCNT value to 0.
14.3 Operation
The style (register name)_(channel number) is used in cases where the same or a
similar function is implemented on more than one channel.
Example: CMCSR_0
When bit names are given in this manual, the higher-order bits are to the left and the
lower-order bits are to the right.
Example: CKS1, CKS0
(1) Registers
(2) Bits
Rev. 0.50, 10/04, page 416 of 914
14.2.2 Compare Match Control/Status Register_0, _1 (CMCSR_0, CMCSR_1)
14.3.1 Interval Count Operation
(4)
(2) (3)
(1)
Binary numbers are given as B'xxxx, hexadecimal are given as H'xxxx, and decimal
are given as xxxx.
Examples: B'11 or 11, H'EFA0, 1234
(3) Numbers
An overbar is added to the names of active-low signals.
Example: WDTOVF
Note: The bit names and sentences in the above figure are examples, and have nothing to do
with the contents of this manual.
(4) Symbols
When an internal clock is selected with the CKS1 and CKS0 bits in CMCSR and the STR bit in
CMSTR is set to 1, CMCNT starts incrementing using the selected clock. When the values in
CMCNT and the compare match constant register (CMCOR) match, CMCNT is cleared to H'0000
and the CMF flag in CMCSR is set to 1. When the CKS1 and CKS0 bits are set to B'01 at this time,
a f/4 clock is selected.

• Notation in bit figures and tables describing arrangements of bits
Each register description includes a figure that illustrates the arrangement of bits and a table
that describes the meanings of settings in the bits.
Indicates the bit number.
In the case of a 32-bit register, the bits are arranged in order from 31 to 0, and in the case
of a 16-bit register, the bits are arranged in the order from 15 to 0.
The short form of the name of the bit or bit field within the register.
When the individual bits of bit fields have to be clearly indicated, notation allowing this is
included (e.g., ASID[3:0]).
A reserved bit is indicated by −.
Instead of a bit name, a blank is used for some bits, such as those of timer counters.
(1) Bit
(2) Bit Name
(1) (2)
Indicates the value of each bit after a power-on reset, i.e., the initial value.
0: Initial value is 0
1: Initial value is 1
−: Initial value is undefined
(3) Initial Value
(3)
Indicates whether each bit is readable or writable, or either writing to or reading from the bit is
prohibited.
The notation is as follows:
R/W:
R/(W):
R:
W:
Bit or field is readable and writable.
Bit or field is readable and writable.
However, writing is only performed to clear the flag.
Bit or field is readable and writable.
However, "R" is indicated for all reserved bits. When writing to the bit is required, write
the value stated in the bit table or the initial value.
Bit or field is readable and writable.
However, only the value in the bit table is guaranteed when reading from the bit.
Note: The bit names and sentences in the above figure are examples, and have nothing to do with the contents of this
manual.
(4) R/W

Section 1 Overview
1.1 SH7211 Features
This LSI is a single-chip RISC microprocessor that integrates a Renesas Technology original
RISC CPU core with peripheral functions required for system configuration.
The CPU in this LSI has a RISC-type (Reduced Instruction Set Computer) instruction set and uses
a superscalar architecture and a Harvard architecture, which greatly improves instruction
execution speed. In addition, the 32-bit internal-bus architecture enhances data processing power.
With this CPU, it has become possible to assemble low-cost, high-performance, and high-
functioning systems, even for applications that were previously impossible with microprocessors,
such as realtime control, which demands high speeds.
In addition, this LSI includes on-chip peripheral functions necessary for system configuration,
such as a large-capacity ROM, a ROM cache, a RAM, a direct memory access controller
(DMAC), multi-function timer pulse units 2 (MTU2 and MTU2S), a serial communication
interface with FIFO (SCIF), an A/D converter, a D/A converter, an interrupt controller (INTC),
I/O ports, and I2C bus interface 3 (IIC3).
This LSI also provides an external memory access support function to enable direct connection to
various memory devices or peripheral LSIs.
These on-chip functions significantly reduce costs of designing and manufacturing application
systems.
The features of this LSI are listed in table 1.1.

2.1 Register Configuration
The register set consists of sixteen 32-bit general registers, four 32-bit control registers, and four
32-bit system registers.
2.1.1 General Registers
Figure 2.1 shows the general registers.
The sixteen 32-bit general registers are numbered R0 to R15. General registers are used for data
processing and address calculation. R0 is also used as an index register. Several instructions have
R0 fixed as their only usable register. R15 is used as the hardware stack pointer (SP). Saving and
restoring the status register (SR) and program counter (PC) in exception handling is accomplished
by referencing the stack using R15.

2.1.2 Control Registers
The control registers consist of four 32-bit registers: the status register (SR), the global base
register (GBR), the vector base register (VBR), and the jump table base register (TBR).
The status register indicates instruction processing states.
The global base register functions as a base address for the GBR indirect addressing mode to
transfer data to the registers of on-chip peripheral modules.
The vector base register functions as the base address of the exception handling vector area
(including interrupts).
The jump table base register functions as the base address of the function table area.

2.1.3 System Registers
The system registers consist of four 32-bit registers: the high and low multiply and accumulate
registers (MACH and MACL), the procedure register (PR), and the program counter (PC). MACH
and MACL store the results of multiply or multiply and accumulate operations. PR stores the
return address from a subroutine procedure. PC indicates the program address being executed and
controls the flow of the processing.

2.1.4 Register Banks
For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and
system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried
out using a register bank. The register contents are automatically saved in the bank after the CPU
accepts an interrupt that uses a register bank. Restoration from the bank is executed by issuing a
RESBANK instruction in an interrupt processing routine.
For details, refer to the SH-2A, SH2A-FPU Software Manual.

2.2 Data Formats
2.2.1 Data Format in Registers
Register operands are always longwords (32 bits). If the size of memory operand is a byte (8 bits)
or a word (16 bits), it is changed into a longword by expanding the sign-part when loaded into a
register.
31 0
Longword
Figure 2.4 Data Format in Registers
2.2.2 Data Formats in Memory
Memory data formats are classified into bytes, words, and longwords. Memory can be accessed in
8-bit bytes, 16-bit words, or 32-bit longwords. A memory operand of fewer than 32 bits is stored
in a register in sign-extended or zero-extended form.
A word operand should be accessed at a word boundary (an even address of multiple of two bytes:
address 2n), and a longword operand at a longword boundary (an even address of multiple of four
bytes: address 4n). Otherwise, an address error will occur. A byte operand can be accessed at any
address.
Only big-endian byte order can be selected for the data format.
Data formats in memory are shown in figure 2.5.

2.2.3 Immediate Data Format
Byte (8-bit) immediate data is located in an instruction code. Immediate data accessed by the
MOV, ADD, and CMP/EQ instructions is sign-extended and handled in registers as longword
data. Immediate data accessed by the TST, AND, OR, and XOR instructions is zero-extended and
handled as longword data. Consequently, AND instructions with immediate data always clear the
upper 24 bits of the destination register.
20-bit immediate data is located in the code of a MOVI20 or MOVI20S 32-bit transfer instruction.
The MOVI20 instruction stores immediate data in the destination register in sign-extended form.
The MOVI20S instruction shifts immediate data by eight bits in the upper direction, and stores it
in the destination register in sign-extended form.
Word or longword immediate data is not located in the instruction code, but rather is stored in a
memory table. The memory table is accessed by an immediate data transfer instruction (MOV)
using the PC relative addressing mode with displacement.
See examples given in section 2.3.1 (10), Immediate Data.

2.3 Instruction Features
2.3.1 RISC-Type Instruction Set
Instructions are RISC type. This section details their functions.
(1) 16-Bit Fixed-Length Instructions
Basic instructions have a fixed length of 16 bits, improving program code efficiency.
(2) 32-Bit Fixed-Length Instructions
The SH-2A additionally features 32-bit fixed-length instructions, improving performance and ease
of use.
(3) One Instruction per State
Each basic instruction can be executed in one cycle using the pipeline system.
(4) Data Length
Longword is the standard data length for all operations. Memory can be accessed in bytes, words,
or longwords. Byte or word data in memory is sign-extended and handled as longword data.
Immediate data is sign-extended for arithmetic operations or zero-extended for logic operations. It
is also handled as longword data.
Table 2.2 Sign Extension of Word Data
SH2-A CPU Description Example of Other CPU
MOV.W @(disp,PC),R1
ADD R1,R0
.........
.DATA.W H'1234
Data is sign-extended to 32 bits,
and R1 becomes H'00001234. It is
next operated upon by an ADD
instruction.
ADD.W #H'1234,R0
Note: @(disp, PC) accesses the immediate data.
(5) Load-Store Architecture
Basic operations are executed between registers. For operations that involve memory access, data
is loaded to the registers and executed (load-store architecture). Instructions such as AND that
manipulate bits, however, are executed directly in memory.
Section 2 CPU
Rev. 3.00 Mar. 04, 2009 Page 23 of 1168
REJ09B0344-0300
(6) Delayed Branch Instructions
With the exception of some instructions, unconditional branch instructions, etc., are executed as
delayed branch instructions. With a delayed branch instruction, the branch is taken after execution
of the instruction immediately following the delayed branch instruction. This reduces disturbance
of the pipeline control when a branch is taken.
In a delayed branch, the actual branch operation occurs after execution of the slot instruction.
However, instruction execution such as register updating excluding the actual branch operation, is
performed in the order of delayed branch instruction → delay slot instruction. For example, even
though the contents of the register holding the branch destination address are changed in the delay
slot, the branch destination address remains as the register contents prior to the change.
Table 2.3 Delayed Branch Instructions
SH-2A CPU Description Example of Other CPU
BRA TRGET
ADD R1,R0
Executes the ADD before
branching to TRGET.
ADD.W R1,R0
BRA TRGET
(7) Unconditional Branch Instructions with No Delay Slot
The SH-2A additionally features unconditional branch instructions in which a delay slot
instruction is not executed. This eliminates unnecessary NOP instructions, and so reduces the code
size.
(8) Multiply/Multiply-and-Accumulate Operations
16-bit × 16-bit → 32-bit multiply operations are executed in one to two cycles. 16-bit × 16-bit +
64-bit → 64-bit multiply-and-accumulate operations are executed in two to three cycles. 32-bit ×
32-bit → 64-bit multiply and 32-bit × 32-bit + 64-bit → 64-bit multiply-and-accumulate
operations are executed in two to four cycles.
(9) T Bit
The T bit in the status register (SR) changes according to the result of the comparison. Whether a
conditional branch is taken or not taken depends upon the T bit condition (true/false). The number
of instructions that change the T bit is kept to a minimum to improve the processing speed.

(10) Immediate Data
Byte immediate data is located in an instruction code. Word or longword immediate data is not
located in instruction codes but in a memory table. The memory table is accessed by an immediate
data transfer instruction (MOV) using the PC relative addressing mode with displacement.
With the SH-2A, 17- to 28-bit immediate data can be located in an instruction code. However, for
21- to 28-bit immediate data, an OR instruction must be executed after the data is transferred to a
register.

(11) Absolute Address
When data is accessed by an absolute address, the absolute address value should be placed in the
memory table in advance. That value is transferred to the register by loading the immediate data
during the execution of the instruction, and the data is accessed in register indirect addressing
mode.
With the SH-2A, when data is referenced using an absolute address not exceeding 28 bits, it is also
possible to transfer immediate data located in the instruction code to a register and to reference the
data in register indirect addressing mode. However, when referencing data using an absolute
address of 21 to 28 bits, an OR instruction must be used after the data is transferred to a register.

When data is accessed by 16-bit or 32-bit displacement, the displacement value should be placed
in the memory table in advance. That value is transferred to the register by loading the immediate
data during the execution of the instruction, and the data is accessed in the indexed indirect
register addressing mode.

—: No change
Notes: 1. Instruction execution cycles: The execution cycles shown in the table are minimums. In
practice, the number of instruction execution states will be increased in cases such as
the following:
a. When there is a conflict between an instruction fetch and a data access
b. When the destination register of a load instruction (memory → register) is the same
as the register used by the next instruction.
2. Depending on the operand size, displacement is scaled by ×1, ×2, or ×4. For details,
refer to the SH-2A, SH2A-FPU Software Manual.

REJ09B0344-0300
(1) Reset State
In the reset state, the CPU is reset. There are two kinds of reset, power-on reset and manual reset.
(2) Exception Handling State
The exception handling state is a transient state that occurs when exception handling sources such
as resets or interrupts alter the CPU’s processing state flow.
For a reset, the initial values of the program counter (PC) (execution start address) and stack
pointer (SP) are fetched from the exception handling vector table and stored; the CPU then
branches to the execution start address and execution of the program begins.
For an interrupt, the stack pointer (SP) is accessed and the program counter (PC) and status
register (SR) are saved to the stack area. The exception service routine start address is fetched
from the exception handling vector table; the CPU then branches to that address and the program
starts executing, thereby entering the program execution state.
(3) Program Execution State
In the program execution state, the CPU sequentially executes the program.
(4) Power-Down State
In the power-down state, the CPU stops operating to reduce power consumption. The SLEEP
instruction places the CPU in the sleep mode or the software standby mode.
(5) Bus-Released State
In the bus-released state, the CPU releases bus to a device that has requested it.

Section 3 MCU Operating Modes
3.1 Selection of Operating Modes
This LSI has four MCU operating modes and three on-chip flash memory programming modes.
The operating mode is determined by the setting of FWE, MD1, and MD0 pins. Table 3.1 shows
the allowable combinations of these pin settings; do not set these pins in the other way than the
shown combinations.
When power is applied to the system, be sure to conduct power-on reset.
The MCU operating mode can be selected from MCU extension modes 0 to 2 and single chip
mode. For the on-chip flash memory programming mode, boot mode, user boot mode, and user
program mode which are on-chip programming modes are available.

Section 4 Clock Pulse Generator (CPG)
This LSI has a clock pulse generator (CPG) that generates an internal clock (Iφ), a peripheral clock
(Pφ), a bus clock (Bφ), an MTU2S clock (Mφ), and an AD clock (Aφ). The CPG consists of a
crystal oscillator, PLL circuits, and divider circuits.
4.1 Features
• Clock operating modes
Either the internal crystal resonator or the input on the external clock-signal line can be
selected.
• Five clocks generated independently
An internal clock (Iφ) for the CPU, a peripheral clock (Pφ) for the peripheral modules, a bus
clock (Bφ = CK) for the external bus interface, an MTU2S clock (Mφ) for the MTU2S module,
and an AD clock (Aφ) for the ADC module can be generated independently.
• Frequency change function
Internal and peripheral clock frequencies can be changed independently using the PLL (phase
locked loop) circuits and divider circuits within the CPG. Frequencies are changed by software
using frequency control register (FRQCR) settings.
• Power-down mode control
The clock can be stopped for sleep mode and software standby mode, and specific modules can
be stopped using the module standby function. For details on clock control in the power-down
modes, see section 23, Power-Down Modes.
Figure 4.1 shows a block diagram of the clock pulse generator.

REJ09B0344-0300
The clock pulse generator blocks function as follows:
(1) PLL Circuit 1
PLL circuit 1 multiplies the input clock frequency from the CK pin by 1, 2, or 4. The
multiplication rate is set by the frequency control register. When this is done, the phase of the
rising edge of the internal clock (Iφ) is controlled so that it will agree with the phase of the rising
edge of the CK pin.
(2) PLL Circuit 2
PLL circuit 2 multiplies the input clock frequency from the crystal oscillator or EXTAL pin by 4.
The multiplication rate is fixed according to the clock operating mode. The clock operating mode
is specified by the MD_CLK0 and MD_CLK2 pins. For details on the clock operating mode, see
table 4.2.
(3) Crystal Oscillator
The crystal oscillator is an oscillation circuit in which a crystal resonator is connected to the
XTAL pin or EXTAL pin. This can be used according to the clock operating mode.
(4) Divider 1
Divider 1 generates a clock signal at the operating frequency used by the internal clock (Iφ), the
bus clock (Bφ), the peripheral clock (Pφ), the MTU2S clock (Mφ), or the AD clock (Aφ). The
operating frequency can be 1, 1/2, 1/4, or 1/8 times the output frequency of PLL circuit 1.
However, set the internal clock (Iφ) so that its frequency is not less than the clock frequency of the
CK pin, and set the peripheral clock (Pφ) so that its frequency is not more than the clock frequency
of the CK pin. The division ratio is set in the frequency control register (FRQCR).
(5) Clock Frequency Control Circuit
The clock frequency control circuit controls the clock frequency using the MD_CLK0 and
MD_CLK2 pins and the frequency control register (FRQCR).
Section 4 Clock Pulse Generator (CPG)
Rev. 3.00 Mar. 04, 2009 Page 64 of 1168
REJ09B0344-0300
(6) Standby Control Circuit
The standby control circuit controls the states of the clock pulse generator and other modules
during clock switching, or sleep or software standby mode.
(7) Frequency Control Register (FRQCR)
The frequency control register (FRQCR) has control bits assigned for the following functions:
clock output/non-output from the CK pin during software standby mode, the frequency
multiplication ratio of PLL circuit 1, and the frequency division ratio of the internal clock (Iφ) and
the peripheral clock (Pφ).
(8) MTU2S Clock Frequency Control Register (MCLKCR)
The MTU2S clock frequency control register (MCLKCR) has control bits assigned for the
following functions: MTU2S clock (Mφ) output/non-output and the frequency division ratio.
(9) AD Clock Frequency Control Register (ACLKCR)
The AD clock frequency control register (ACLKCR) has control bits assigned for the following
functions: AD clock (Aφ) output/non-output and the frequency division ratio.
(10) Standby Control Register
The standby control register has bits for controlling the power-down modes. See section 23,
Power-Down Modes, for more information.

• Mode 6
The frequency of the signal received from the EXTAL pin or crystal oscillator is quadrupled
by the PLL circuit 2 before it is supplied to the LSI as the clock signal. This allows a crystal
with a lower frequency to be used. Either a crystal resonator with a frequency in the range
from 8 to 10 MHz or an external signal in the same frequency range input on the EXTAL pin
can be used. When the CK output is in use, the frequency range is from 32 to 40 MHz. When
an input signal on the EXTAL pin is in use, the XTAL pin should be left open.

Notes: 1. The ratio of clock frequencies, where the input clock frequency is assumed to be 1.
2. The frequency of the clock input from the EXTAL pin or the frequency of the crystal resonator.
Caution: 1. The frequency of the internal clock (Iφ) is the frequency of the signal input to the CK pin after
multiplication by the frequency-multiplier of PLL circuit 1 and division by the divider's divisor. Set
the frequency of the internal clock to 160 MHz or less but not less than the frequency of the
signal on the CK pin.
2. The frequency of the peripheral clock (Pφ) is the frequency of the signal input to the CK pin after
multiplication by the frequency-multiplier of PLL circuit 1 and division by the divider's divisor. Set
the frequency of the peripheral clock to 40 MHz or less. In addition, do not set a higher
frequency for the internal clock than the frequency on the CK pin.
3. The frequency multiplier of PLL circuit 1 can be selected as ×1, ×2, or ×4. The divisor of the
divider can be selected as ×1, ×1/2, ×1/4, or ×1/8. The settings are made in the frequency-
control register (FRQCR).
4. The signal output by PLL circuit 1 is the signal on the CK pin multiplied by the frequency
multiplier of PLL circuit 1. Ensure that the frequency of the signal from PLL circuit 1 is no more
than 160 MHz.

4.5 Changing the Frequency
The frequency of the internal clock (Iφ) and peripheral clock (Pφ) can be changed either by
changing the multiplication rate of PLL circuit 1 or by changing the division rates of divider. All
of these are controlled by software through the frequency control register (FRQCR). The methods
are described below.
4.5.1 Changing the Multiplication Rate
A PLL settling time is required when the multiplication rate of PLL circuit 1 is changed. When the
multiplication rate is changed, the LSI temporarily stops automatically and the internal watchdog
timer (WDT) starts counting the settling time. When the count of the WDT overflows, the LSI
restarts operating with the set clock frequency. The following shows this setting procedure.
1. In the initial state, the multiplication rate of PLL circuit 1 is 1 time.
2. Set a value that will become the specified oscillation settling time in the WDT and stop the
WDT. The following must be set:
WTCSR.TME = 0: WDT stops
WTCSR.CKS[2:0]: Division ratio of WDT count clock
WTCNT counter: Initial counter value
For setting of the counter, determine the overflow period with the frequency after the
peripheral clock (Pφ) setting change.
3. Set the desired value in the STC[1:0] bits. The division ratio can also be set in the IFC[2:0] and
PFC[2:0] bits.
4. This LSI pauses temporarily and the WDT starts incrementing. The internal and peripheral
clocks both stop and the WDT is supplied with the clock. The clock will continue to be output
at the CK pin. This state is the same as software standby mode. Whether or not registers are
initialized depends on the module. For details, see table 23.4 in section 23, Power-Down
Modes.
5. Supply of the clock that has been set begins at WDT count overflow, and this LSI begins
operating again. The WDT stops counting after it overflows.
Section 4 Clock Pulse Generator (CPG)
Rev. 3.00 Mar. 04, 2009 Page 74 of 1168
REJ09B0344-0300
4.5.2 Changing the Division Ratio
Counting by the WDT does not proceed if the frequency divisor is changed but the multiplier is
not.
1. In the initial state, IFC[2:0] = B'000 and PFC[2:0] = B'011.
2. Set the desired value in the IFC[2:0] and PFC[2:0] bits. The values that can be set are limited
by the clock operating mode and the multiplication rate of PLL circuit 1. Note that if the
wrong value is set, this LSI will malfunction.
3. After the register bits (IFC[2:0] and PFC[2:0]) have been set, the clock is supplied of the new
division ratio.
Note: When executing the SLEEP instruction after the frequency has been changed, be sure to
read the frequency control register (FRQCR) three times before executing the SLEEP
instruction.

4.6.1 Note on Using an External Crystal Resonator
Place the crystal resonator and capacitors CL1 and CL2 as close to the XTAL and EXTAL pins as
possible. In addition, to minimize induction and thus obtain oscillation at the correct frequency,
the capacitors to be attached to the resonator must be grounded to the same ground. Do not bring
wiring patterns close to these components.

4.6.2 Note on Bypass Capacitor
A multilayer ceramic capacitor should be inserted for each pair of Vss and Vcc as a bypass
capacitor as many as possible. The bypass capacitor must be inserted as close to the power supply
pins of the LSI as possible. Note that the capacitance and frequency characteristics of the bypass
capacitor must be appropriate for the operating frequency of the LSI.
4.6.3 Note on Using a PLL Oscillation Circuit
In the PLLVcc and PLLVss connection pattern for the PLL, signal lines from the board power
supply pins must be as short as possible and pattern width must be as wide as possible to reduce
inductive interference.
Since the analog power supply pins of the PLL are sensitive to the noise, the system may
malfunction due to inductive interference at the other power supply pins. To prevent such
malfunction, the analog power supply pin Vcc and digital power supply pin VccQ should not
supply the same resources on the board if at all possible.

5.1.2 Exception Handling Operations
The exception handling sources are detected and begin processing according to the timing shown
in table 5.2.
Table 5.2 Timing of Exception Source Detection and Start of Exception Handling
Exception Source Timing of Source Detection and Start of Handling
Power-on reset Starts when the RES pin changes from low to high, when the
H-UDI reset negate command is set after the H-UDI reset
assert command has been set, or when the WDT overflows.
Reset
Manual reset Starts when the MRES pin changes from low to high or when
the WDT overflows.
Address error Detected when instruction is decoded and starts when the
previous executing instruction finishes executing.

previous executing instruction finishes executing.
Bank underflow Starts upon attempted execution of a RESBANK instruction
when saving has not been performed to register banks.
Register bank

(H'80000000) by −1.
Section 5 Exception Handling
Rev. 3.00 Mar. 04, 2009 Page 80 of 1168
REJ09B0344-0300
When exception handling starts, the CPU operates as follows:
(1) Exception Handling Triggered by Reset
The initial values of the program counter (PC) and stack pointer (SP) are fetched from the
exception handling vector table (PC and SP are respectively the H'00000000 and H'00000004
addresses for power-on resets and the H'00000008 and H'0000000C addresses for manual resets).
See section 5.1.3, Exception Handling Vector Table, for more information. The vector base
register (VBR) is then initialized to H'00000000, the interrupt mask level bits (I3 to I0) of the
status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized. The BN
bit in IBNR of the interrupt controller (INTC) is also initialized to 0. The program begins running
from the PC address fetched from the exception handling vector table.
(2) Exception Handling Triggered by Address Errors, Register Bank Errors, Interrupts,
and Instructions
SR and PC are saved to the stack indicated by R15. In the case of interrupt exception handling
other than NMI or UBC with usage of the register banks enabled, general registers R0 to R14,
control register GBR, system registers MACH, MACL, and PR, and the vector number of the
interrupt exception handling to be executed are saved to the register banks. In the case of
exception handling due to an address error, register bank error, NMI interrupt, UBC interrupt, or
instruction, saving to a register bank is not performed. When saving is performed to all register
banks, automatic saving to the stack is performed instead of register bank saving. In this case, an
interrupt controller setting must have been made so that register bank overflow exceptions are not
accepted (the BOVE bit in IBNR of the INTC is 0). If a setting to accept register bank overflow
exceptions has been made (the BOVE bit in IBNR of the INTC is 1), register bank overflow
exception will be generated. In the case of interrupt exception handling, the interrupt priority level
is written to the I3 to I0 bits in SR. In the case of exception handling due to an address error or
instruction, the I3 to I0 bits are not affected. The start address is then fetched from the exception
handling vector table and the program begins running from that address.

REJ09B0344-0300
5.1.3 Exception Handling Vector Table
Before exception handling begins running, the exception handling vector table must be set in
memory. The exception handling vector table stores the start addresses of exception service
routines. (The reset exception handling table holds the initial values of PC and SP.)
All exception sources are given different vector numbers and vector table address offsets, from
which the vector table addresses are calculated. During exception handling, the start addresses of
the exception service routines are fetched from the exception handling vector table, which is
indicated by this vector table address.
Table 5.3 shows the vector numbers and vector table address offsets. Table 5.4 shows how vector
table addresses are calculated.

5.2 Resets
5.2.1 Types of Reset
A reset is the highest-priority exception handling source. There are two kinds of reset, power-on
and manual. As shown in table 5.5, the CPU state is initialized in both a power-on reset and a
manual reset. On-chip peripheral module registers are initialized by a power-on reset, but not by a
manual reset.

REJ09B0344-0300
5.2.2 Power-On Reset
(1) Power-On Reset by Means of RES Pin
When the RES pin is driven low, this LSI enters the power-on reset state. To reliably reset this
LSI, the RES pin should be kept at the low level for the duration of the oscillation settling time at
power-on or when in software standby mode (when the clock is halted), or at least 20-tcyc when
the clock is running. In the power-on reset state, the internal state of the CPU and all the on-chip
peripheral module registers are initialized. See appendix A, Pin States, for the status of individual
pins during the power-on reset state.
In the power-on reset state, power-on reset exception handling starts when the RES pin is first
driven low for a fixed period and then returned to high. The CPU operates as follows:
1. The initial value (execution start address) of the program counter (PC) is fetched from the
exception handling vector table.
2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table.
3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to
I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are
initialized. The BN bit in IBNR of the INTC is also initialized to 0.
4. The values fetched from the exception handling vector table are set in the PC and SP, and the
program begins executing.
Be certain to always perform power-on reset processing when turning the system power on.
(2) Power-On Reset by Means of H-UDI Reset Assert Command
When the H-UDI reset assert command is set, this LSI enters the power-on reset state. Power-on
reset by means of an H-UDI reset assert command is equivalent to power-on reset by means of the
RES pin. Setting the H-UDI reset negate command cancels the power-on reset state. The time
required between an H-UDI reset assert command and H-UDI reset negate command is the same
as the time to keep the RES pin low to initiate a power-on reset. In the power-on reset state
generated by an H-UDI reset assert command, setting the H-UDI reset negate command starts
power-on reset exception handling. The CPU operates in the same way as when a power-on reset
was caused by the RES pin.
Section 5 Exception Handling
Rev. 3.00 Mar. 04, 2009 Page 85 of 1168
REJ09B0344-0300
(3) Power-On Reset Initiated by WDT
When a setting is made for a power-on reset to be generated in the WDT’s watchdog timer mode,
and WTCNT of the WDT overflows, this LSI enters the power-on reset state.
In this case, WRCSR of the WDT and FRQCR of the CPG are not initialized by the reset signal
generated by the WDT.
If a reset caused by the RES pin or the H-UDI reset assert command occurs simultaneously with a
reset caused by WDT overflow, the reset caused by the RES pin or the H-UDI reset assert
command has priority, and the WOVF bit in WRCSR is cleared to 0. When power-on reset
exception processing is started by the WDT, the CPU operates in the same way as when a power-
on reset was caused by the RES pin.
Section 5 Exception Handling
Rev. 3.00 Mar. 04, 2009 Page 86 of 1168
REJ09B0344-0300
5.2.3 Manual Reset
(1) Manual Reset by Means of MRES Pin
When the MRES pin is driven low, this LSI enters the manual reset state. To reset this LSI without
fail, the MRES pin should be kept at the low level for at least 20-tcyc. In the manual reset state,
the CPU’s internal state is initialized, but all the on-chip peripheral module registers are not
initialized. In the manual reset state, manual reset exception handling starts when the MRES pin is
first driven low for a fixed period and then returned to high. The CPU operates as follows:
1. The initial value (execution start address) of the program counter (PC) is fetched from the
exception handling vector table.
2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table.
3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to
I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are
initialized. The BN bit in IBNR of the INTC is also initialized to 0.
4. The values fetched from the exception handling vector table are set in the PC and SP, and the
program begins executing.
(2) Manual Reset Initiated by WDT
When a setting is made for a manual reset to be generated in the WDT’s watchdog timer mode,
and WTCNT of the WDT overflows, this LSI enters the manual reset state.
When manual reset exception processing is started by the WDT, the CPU operates in the same
way as when a manual reset was caused by the MRES pin.
When a manual reset is generated, the bus cycle is retained, but if a manual reset occurs while the
bus is released or during DMAC burst transfer, manual reset exception handling will be deferred
until the CPU acquires the bus. However, if the interval from generation of the manual reset until
the end of the bus cycle is equal to or longer than the fixed internal manual reset interval cycles,
the internal manual reset source is ignored instead of being deferred, and manual reset exception
handling is not executed.

5.3.2 Address Error Exception Handling
When an address error occurs, the bus cycle in which the address error occurred ends*. When the
executing instruction then finishes, address error exception handling starts. The CPU operates as
follows:
1. The exception service routine start address which corresponds to the address error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction.
4. After jumping to the address fetched from the exception handling vector table, program
execution starts. The jump that occurs is not a delayed branch.
Note: * This is the case in which an address error was caused by data read or write. When an
address error is caused by an instruction fetch, and if the bus cycle in which the address
error occurred does not end by step 3 above, the CPU restarts the address error
exception handling until the bus cycle ends.

5.4 Register Bank Errors
5.4.1 Register Bank Error Sources
(1) Bank Overflow
In the state where saving has already been performed to all register bank areas, bank overflow
occurs when acceptance of register bank overflow exception has been set by the interrupt
controller (the BOVE bit in IBNR of the INTC is set to 1) and an interrupt that uses a register
bank has occurred and been accepted by the CPU.
(2) Bank Underflow
Bank underflow occurs when an attempt is made to execute a RESBANK instruction while saving
has not been performed to register banks.
5.4.2 Register Bank Error Exception Handling
When a register bank error occurs, register bank error exception handling starts. The CPU operates
as follows:
1. The exception service routine start address which corresponds to the register bank error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction for a bank overflow, and the start
address of the executed RESBANK instruction for a bank underflow.
To prevent multiple interrupts from occurring at a bank overflow, the interrupt priority level
that caused the bank overflow is written to the interrupt mask level bits (I3 to I0) of the status
register (SR).
4. After jumping to the address fetched from the exception handling vector table, program
execution starts. The jump that occurs is not a delayed branch.

5.5.2 Interrupt Priority Level
The interrupt priority order is predetermined. When multiple interrupts occur simultaneously
(overlap), the interrupt controller (INTC) determines their relative priorities and starts processing
according to the results.
The priority order of interrupts is expressed as priority levels 0 to 16, with priority 0 the lowest
and priority 16 the highest. The NMI interrupt has priority 16 and cannot be masked, so it is
always accepted. The user break interrupt and H-UDI interrupt priority level is 15. Priority levels
of IRQ interrupts, and on-chip peripheral module interrupts can be set freely using the interrupt
priority registers 01, 02, and 05 to 15 (IPR01, IPR02, and IPR05 to IPR15) of the INTC as shown
in table 5.8. The priority levels that can be set are 0 to 15. Level 16 cannot be set. See section
6.3.1, Interrupt Priority Registers 01, 02, 05 to 15 (IPR01, IPR02, IPR05 to IPR15), for details of
IPR01, IPR02, and IPR05 to IPR15.

5.5.3 Interrupt Exception Handling
When an interrupt occurs, its priority level is ascertained by the interrupt controller (INTC). NMI
is always accepted, but other interrupts are only accepted if they have a priority level higher than
the priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR).
When an interrupt is accepted, interrupt exception handling begins. In interrupt exception
handling, the CPU fetches the exception service routine start address which corresponds to the
accepted interrupt from the exception handling vector table, and saves SR and the program counter
(PC) to the stack. In the case of interrupt exception handling other than NMI or UBC with usage
of the register banks enabled, general registers R0 to R14, control register GBR, system registers
MACH, MACL, and PR, and the vector number of the interrupt exception handling to be executed
are saved in the register banks. In the case of exception handling due to an address error, NMI
interrupt, UBC interrupt, or instruction, saving is not performed to the register banks. If saving has
been performed to all register banks (0 to 14), automatic saving to the stack is performed instead
of register bank saving. In this case, an interrupt controller setting must have been made so that
register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the INTC is 0). If a
setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the
INTC is 1), register bank overflow exception occurs. Next, the priority level value of the accepted
interrupt is written to the I3 to I0 bits in SR. For NMI, however, the priority level is 16, but the
value set in the I3 to I0 bits is H'F (level 15). Then, after jumping to the start address fetched from
the exception handling vector table, program execution starts. The jump that occurs is not a
delayed branch. See section 6.6, Operation, for further details of interrupt exception handling.

5.6.2 Trap Instructions
When a TRAPA instruction is executed, trap instruction exception handling starts. The CPU
operates as follows:
1. The exception service routine start address which corresponds to the vector number specified
in the TRAPA instruction is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the TRAPA instruction.
4. After jumping to the address fetched from the exception handling vector table, program
execution starts. The jump that occurs is not a delayed branch.
5.6.3 Slot Illegal Instructions
An instruction placed immediately after a delayed branch instruction is said to be placed in a delay
slot. When the instruction placed in the delay slot is undefined code, an instruction that rewrites
the PC, a 32-bit instruction, an RESBANK instruction, a DIVS instruction, or a DIVU instruction,
slot illegal exception handling starts when such kind of instruction is decoded. The CPU operates
as follows:
1. The exception service routine start address is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the jump address of the
delayed branch instruction immediately before the undefined code, the instruction that rewrites
the PC, the 32-bit instruction, the RESBANK instruction, the DIVS instruction, or the DIVU
instruction.
4. After jumping to the address fetched from the exception handling vector table, program
execution starts. The jump that occurs is not a delayed branch.

REJ09B0344-0300
5.6.4 General Illegal Instructions
When undefined code placed anywhere other than immediately after a delayed branch instruction
(i.e., in a delay slot) is decoded, general illegal instruction exception handling starts. The CPU
handles general illegal instructions in the same way as slot illegal instructions. Unlike processing
of slot illegal instructions, however, the program counter value stored is the start address of the
undefined code.
5.6.5 Integer Division Instructions
When an integer division instruction performs division by zero or the result of integer division
overflows, integer division instruction exception handling starts. The instructions that may become
the source of division-by-zero exception are DIVU and DIVS. The only source instruction of
overflow exception is DIVS, and overflow exception occurs only when the negative maximum
value is divided by −1. The CPU operates as follows:
1. The exception service routine start address which corresponds to the integer division
instruction exception that occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
integer division instruction at which the exception occurred.
4. After jumping to the address fetched from the exception handling vector table, program
execution starts. The jump that occurs is not a delayed branch.

5.7 When Exception Sources Are Not Accepted
When an address error, register bank error (overflow), or interrupt is generated immediately after a
delayed branch instruction, it is sometimes not accepted immediately but stored instead, as shown
in table 5.10. When this happens, it will be accepted when an instruction that can accept the
exception is decoded.

5.9 Usage Notes
5.9.1 Value of Stack Pointer (SP)
The value of the stack pointer must always be a multiple of four. If it is not, an address error will
occur when the stack is accessed during exception handling.
5.9.2 Value of Vector Base Register (VBR)
The value of the vector base register must always be a multiple of four. If it is not, an address error
will occur when the stack is accessed during exception handling.
5.9.3 Address Errors Caused by Stacking of Address Error Exception Handling
When the stack pointer is not a multiple of four, an address error will occur during stacking of the
exception handling (interrupts, etc.) and address error exception handling will start up as soon as
the first exception handling is ended. Address errors will then also occur in the stacking for this
address error exception handling. To ensure that address error exception handling does not go into
an endless loop, no address errors are accepted at that point. This allows program control to be
shifted to the address error exception service routine and enables error processing.
When an address error occurs during exception handling stacking, the stacking bus cycle (write) is
executed. During stacking of the status register (SR) and program counter (PC), the SP is
decremented by 4 for both, so the value of SP will not be a multiple of four after the stacking
either. The address value output during stacking is the SP value, so the address where the error
occurred is itself output. This means the write data stacked will be undefined.

Section 6 Interrupt Controller (INTC)
The interrupt controller (INTC) ascertains the priority of interrupt sources and controls interrupt
requests to the CPU. The INTC registers set the order of priority of each interrupt, allowing the
user to process interrupt requests according to the user-set priority.
6.1 Features
• 16 levels of interrupt priority can be set
By setting the thirteen interrupt priority registers, the priorities of IRQ interrupts and on-chip
peripheral module interrupts can be selected from 16 levels for request sources.
• NMI noise canceller function
An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt
exception service routine, the pin state can be checked, enabling it to be used as the noise
canceller function.
• Occurrence of interrupt can be reported externally (IRQOUT pin)
For example, when this LSI has released the bus mastership, this LSI can inform the external
bus master of occurrence of an on-chip peripheral module interrupt and request for the bus
mastership.
• Register banks
This LSI has register banks that enable register saving and restoration required in the interrupt
processing to be performed at high speed.

6.4 Interrupt Sources
There are five types of interrupt sources: NMI, user break, H-UDI, IRQ, and on-chip peripheral
modules. Each interrupt has a priority level (0 to 16), with 0 the lowest and 16 the highest. When
set to level 0, that interrupt is masked at all times.
6.4.1 NMI Interrupt
The NMI interrupt has a priority level of 16 and is accepted at all times. NMI interrupt requests
are edge-detected, and the NMI edge select bit (NMIE) in interrupt control register 0 (ICR0)
selects whether the rising edge or falling edge is detected.
Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets the
interrupt mask level bits (I3 to I0) in the status register (SR) to level 15.
6.4.2 User Break Interrupt
A user break interrupt which occurs when a break condition set in the user break controller (UBC)
matches has a priority level of 15. The user break interrupt exception handling sets the I3 to I0 bits
in SR to level 15. For user break interrupts, see section 7, User Break Controller (UBC).
6.4.3 H-UDI Interrupt
The user debugging interface (H-UDI) interrupt has a priority level of 15, and occurs at serial
input of an H-UDI interrupt instruction. H-UDI interrupt requests are edge-detected and retained
until they are accepted. The H-UDI interrupt exception handling sets the I3 to I0 bits in SR to level
15. For H-UDI interrupts, see section 24, User Debugging Interface (H-UDI).
Section 6 Interrupt Controller (INTC)
Rev. 3.00 Mar. 04, 2009 Page 115 of 1168
REJ09B0344-0300
6.4.4 IRQ Interrupts
IRQ interrupts are input from pins IRQ7 to IRQ0. For the IRQ interrupts, low-level, falling-edge,
rising-edge, or both-edge detection can be selected individually for each pin by the IRQ sense
select bits (IRQ71S to IRQ01S and IRQ70S to IRQ00S) in interrupt control register 1 (ICR1). The
priority level can be set individually in a range from 0 to 15 for each pin by interrupt priority
registers 01 and 02 (IPR01 and IPR02).
When using low-level sensing for IRQ interrupts, an interrupt request signal is sent to the INTC
while the IRQ7 to IRQ0 pins are low. An interrupt request signal is stopped being sent to the
INTC when the IRQ7 to IRQ0 pins are driven high. The status of the interrupt requests can be
checked by reading the IRQ interrupt request bits (IRQ7F to IRQ0F) in the IRQ interrupt request
register (IRQRR).
When using edge-sensing for IRQ interrupts, an interrupt request is detected due to change of the
IRQ7 to IRQ0 pin states, and an interrupt request signal is sent to the INTC. The result of IRQ
interrupt request detection is retained until that interrupt request is accepted. Whether IRQ
interrupt requests have been detected or not can be checked by reading the IRQ7F to IRQ0F bits in
IRQRR. Writing 0 to these bits after reading them as 1 clears the result of IRQ interrupt request
detection.
The IRQ interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the
accepted IRQ interrupt.

6.4.5 On-Chip Peripheral Module Interrupts
On-chip peripheral module interrupts are generated by the following on-chip peripheral modules:
• A/D converter (ADC)
• Direct memory access controller (DMAC)
• Compare match timer (CMT)
• Bus state controller (BSC)
• Watchdog timer (WDT)
• Multi-function timer pulse unit 2 (MTU2)
• Multi-function timer pulse unit 2S (MTU2S)
• Port output enable 2 (POE2)
• I2C bus interface 3 (IIC3)
• Serial communication interface with FIFO (SCIF)
• WAVE interface (WAVEIF)
As every source is assigned a different interrupt vector, the source does not need to be identified in
the exception service routine. A priority level in a range from 0 to 15 can be set for each module
by interrupt priority registers 05 to 15 (IPR05 to IPR15). The on-chip peripheral module interrupt
exception handling sets the I3 to I0 bits in SR to the priority level of the accepted on-chip
peripheral module interrupt.

6.5 Interrupt Exception Handling Vector Table and Priority
Table 6.4 lists interrupt sources and their vector numbers, vector table address offsets, and
interrupt priorities.
Each interrupt source is allocated a different vector number and vector table address offset. Vector
table addresses are calculated from the vector numbers and vector table address offsets. In
interrupt exception handling, the interrupt exception service routine start address is fetched from
the vector table indicated by the vector table address. For details of calculation of the vector table
address, see table 5.4 in section 5, Exception Handling.
The priorities of IRQ interrupts and on-chip peripheral module interrupts can be set freely between
0 and 15 for each pin or module by setting interrupt priority registers 01, 02, and 05 to 15 (IPR01,
IPR02, and IPR05 to IPR15). However, if two or more interrupts specified by the same IPR
among IPR05 to IPR15 occur, the priorities are defined as shown in the IPR setting unit internal
priority of table 6.4, and the priorities cannot be changed. A power-on reset assigns priority level 0
to IRQ interrupts and on-chip peripheral module interrupts. If the same priority level is assigned to
two or more interrupt sources and interrupts from those sources occur simultaneously, they are
processed by the default priorities indicated in table 6.4.

6.6 Operation
6.6.1 Interrupt Operation Sequence
The sequence of interrupt operations is described below. Figure 6.2 shows the operation flow.
1. The interrupt request sources send interrupt request signals to the interrupt controller.
2. The interrupt controller selects the highest-priority interrupt from the interrupt requests sent,
following the priority levels set in interrupt priority registers 01, 02, and 05 to 15 (IPR01,
IPR02, and IPR05 to IPR15). Lower priority interrupts are ignored*. If two of these interrupts
have the same priority level or if multiple interrupts occur within a single IPR, the interrupt
with the highest priority is selected, according to the default priority and IPR setting unit
internal priority shown in table 6.4.
3. The priority level of the interrupt selected by the interrupt controller is compared with the
interrupt level mask bits (I3 to I0) in the status register (SR) of the CPU. If the interrupt
request priority level is equal to or less than the level set in bits I3 to I0, the interrupt request is
ignored. If the interrupt request priority level is higher than the level in bits I3 to I0, the
interrupt controller accepts the interrupt and sends an interrupt request signal to the CPU.
4. When the interrupt controller accepts an interrupt, a low level is output from the IRQOUT pin.
5. The CPU detects the interrupt request sent from the interrupt controller when the CPU decodes
the instruction to be executed. Instead of executing the decoded instruction, the CPU starts
interrupt exception handling (figure 6.4).
6. The interrupt exception service routine start address is fetched from the exception handling
vector table corresponding to the accepted interrupt.
7. The status register (SR) is saved onto the stack, and the priority level of the accepted interrupt
is copied to bits I3 to I0 in SR.
8. The program counter (PC) is saved onto the stack.
9. The CPU jumps to the fetched interrupt exception service routine start address and starts
executing the program. The jump that occurs is not a delayed branch.
10. A high level is output from the IRQOUT pin. However, if the interrupt controller accepts an
interrupt with a higher priority than the interrupt just being accepted, the IRQOUT pin holds
low level.
Section 6 Interrupt Controller (INTC)
Rev. 3.00 Mar. 04, 2009 Page 126 of 1168
REJ09B0344-0300
Notes: The interrupt source flag should be cleared in the interrupt handler. After clearing the
interrupt source flag, "time from occurrence of interrupt request until interrupt controller
identifies priority, compares it with mask bits in SR, and sends interrupt request signal to
CPU" shown in table 6.5 is required before the interrupt source sent to the CPU is actually
cancelled. To ensure that an interrupt request that should have been cleared is not
inadvertently accepted again, read the interrupt source flag after it has been cleared, and
then execute an RTE instruction.
* Interrupt requests that are designated as edge-sensing are held pending until the
interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing
the IRQ interrupt request register (IRQRR). For details, see section 6.4.4, IRQ
Interrupts.
Interrupts held pending due to edge-sensing are cleared by a power-on reset.

6.7 Interrupt Response Time
Table 6.5 lists the interrupt response time, which is the time from the occurrence of an interrupt
request until the interrupt exception handling starts and fetching of the first instruction in the
exception service routine begins. The interrupt processing operations differ in the cases when
banking is disabled, when banking is enabled without register bank overflow, and when banking is
enabled with register bank overflow. Figures 6.4 and 6.5 show examples of pipeline operation
when banking is disabled. Figures 6.6 and 6.7 show examples of pipeline operation when banking
is enabled without register bank overflow. Figures 6.8 and 6.9 show examples of pipeline
operation when banking is enabled with register bank overflow.

6.8.1 Banked Register and Input/Output of Banks
(1) Banked Register
The contents of the general registers (R0 to R14), global base register (GBR), multiply and
accumulate registers (MACH and MACL), and procedure register (PR), and the vector table
address offset are banked.
(2) Register Banks
This LSI has fifteen register banks, bank 0 to bank 14. Register banks are stacked in first-in last-
out (FILO) sequence. Saving takes place in order, beginning from bank 0, and restoration takes
place in the reverse order, beginning from the last bank saved to.
6.8.2 Bank Save and Restore Operations
(1) Saving to Bank
Figure 6.11 shows register bank save operations. The following operations are performed when an
interrupt for which usage of register banks is allowed is accepted by the CPU:
a. Assume that the bank number bit value in the bank number register (IBNR), BN, is i before the
interrupt is generated.
b. The contents of registers R0 to R14, GBR, MACH, MACL, and PR, and the interrupt vector
table address offset (VTO) of the accepted interrupt are saved in the bank indicated by BN,
bank i.
c. The BN value is incremented by 1.

(2) Restoration from Bank
The RESBANK (restore from register bank) instruction is used to restore data saved in a register
bank. After restoring data from the register banks with the RESBANK instruction at the end of the
interrupt service routine, execute the RTE instruction to return from the exception handling.

REJ09B0344-0300
6.8.3 Save and Restore Operations after Saving to All Banks
If an interrupt occurs and usage of the register banks is enabled for the interrupt accepted by the
CPU in a state where saving has been performed to all register banks, automatic saving to the
stack is performed instead of register bank saving if the BOVE bit in the bank number register
(IBNR) is cleared to 0. If the BOVE bit in IBNR is set to 1, register bank overflow exception
occurs and data is not saved to the stack.
Save and restore operations when using the stack are as follows:
(1) Saving to Stack
1. The status register (SR) and program counter (PC) are saved to the stack during interrupt
exception handling.
2. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are saved to
the stack. The registers are saved to the stack in the order of MACL, MACH, GBR, PR, R14,
R13, …, R1, and R0.
3. The register bank overflow bit (BO) in SR is set to 1.
4. The bank number bit (BN) value in the bank number register (IBNR) remains set to the
maximum value of 15.
(2) Restoration from Stack
When the RESBANK (restore from register bank) instruction is executed with the register bank
overflow bit (BO) in SR set to 1, the CPU operates as follows:
1. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are restored
from the stack. The registers are restored from the stack in the order of R0, R1, …, R13, R14,
PR, GBR, MACH, and MACL.
2. The bank number bit (BN) value in the bank number register (IBNR) remains set to the
maximum value of 15.

Rev. 3.00 Mar. 04, 2009 Page 139 of 1168
REJ09B0344-0300
6.8.4 Register Bank Exception
There are two register bank exceptions (register bank errors): register bank overflow and register
bank underflow.
(1) Register Bank Overflow
This exception occurs if, after data has been saved to all of the register banks, an interrupt for
which register bank use is allowed is accepted by the CPU, and the BOVE bit in the bank number
register (IBNR) is set to 1. In this case, the bank number bit (BN) value in the bank number
register (IBNR) remains set to the bank count of 15 and saving is not performed to the register
bank.
(2) Register Bank Underflow
This exception occurs if the RESBANK (restore from register bank) instruction is executed when
no data has been saved to the register banks. In this case, the values of R0 to R14, GBR, MACH,
MACL, and PR do not change. In addition, the bank number bit (BN) value in the bank number
register (IBNR) remains set to 0.
6.8.5 Register Bank Error Exception Handling
When a register bank error occurs, register bank error exception handling starts. When this
happens, the CPU operates as follows:
1. The exception service routine start address which corresponds to the register bank error that
occurred is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
instruction to be executed after the last executed instruction for a register bank overflow, and
the start address of the executed RESBANK instruction for a register bank underflow. To
prevent multiple interrupts from occurring at a register bank overflow, the interrupt priority
level that caused the register bank overflow is written to the interrupt mask level bits (I3 to I0)
of the status register (SR).
4. Program execution starts from the exception service routine start address.

6.9 Data Transfer with Interrupt Request Signals
Interrupt request signals can be used to activate the DMAC and transfer data.
Interrupt sources that are designated to activate the DMAC are masked without being input to the
INTC. The mask condition is as follows:
Mask condition = DME • (DE0 • interrupt source select 0 + DE1 • interrupt source select 1
+ DE2 • interrupt source select 2 + DE3 • interrupt source select 3 +
DE4 • interrupt source select 4 + DE5 • interrupt source select 5 + DE6
• interrupt source select 6 + DE7 • interrupt source select 7)
Figure 6.13 shows a block diagram of interrupt control.
Here, DME is bit 0 in DMAOR of the DMAC, and DEn (n = 0 to 7) is bit 0 in CHCR0 to CHCR7
of the DMAC. For details, see section 9, Direct Memory Access Controller (DMAC).

6.9.1 Handling Interrupt Request Signals as Sources for CPU Interrupt but Not DMAC
Activating
1 Do not select DMAC activating sources or clear the DME bit to 0. If, DMAC activating
sources are selected, clear the DE bit to 0 for the relevant channel of the DMAC.
2. When interrupts occur, interrupt requests are sent to the CPU.
3. The CPU clears the interrupt source and performs the necessary processing in the interrupt
exception service routine.
6.9.2 Handling Interrupt Request Signals as Sources for Activating DMAC but Not CPU
Interrupt
1. Select DMAC activating sources and set both the DE and DME bits to 1. This masks CPU
interrupt sources regardless of the interrupt priority register settings.
2. Activating sources are applied to the DMAC when interrupts occur.
3. The DMAC clears the interrupt sources when starting transfer.
6.10 Usage Note
6.10.1 Timing to Clear an Interrupt Source
The interrupt source flags should be cleared in the interrupt exception service routine. After
clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt
controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal
to CPU" shown in table 6.5 is required before the interrupt source sent to the CPU is actually
cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently
accepted again, read the interrupt source flag after it has been cleared, and then execute an RTE
instruction.

Section 7 User Break Controller (UBC)
The user break controller (UBC) provides functions that simplify program debugging. These
functions make it easy to design an effective self-monitoring debugger, enabling the chip to debug
programs without using an in-circuit emulator. Instruction fetch or data read/write (bus master
(CPU or DMAC) selection in the case of data read/write), data size, data contents, address value,
and stop timing in the case of instruction fetch are break conditions that can be set in the UBC.
Since this LSI uses a Harvard architecture, instruction fetch on the CPU bus (C bus) is performed
by issuing bus cycles on the instruction fetch bus (F bus), and data access on the C bus is
performed by issuing bus cycles on the memory access bus (M bus). The UBC monitors the C bus
and internal bus (I bus).
7.1 Features
1. The following break comparison conditions can be set.
Number of break channels: four channels (channels 0 to 3)
User break can be requested as the independent condition on channels 0, 1, 2, and 3.
• Address
Comparison of the 32-bit address is maskable in 1-bit units.
One of the three address buses (F address bus (FAB), M address bus (MAB), and I address bus
(IAB)) can be selected.
• Bus master when I bus is selected
Selection of CPU cycles or DMAC cycles
• Bus cycle
Instruction fetch (only when C bus is selected) or data access
• Read/write
• Operand size
Byte, word, and longword
2. Exception handling routine for user-specified break conditions can be executed.
3. In an instruction fetch cycle, it can be selected whether PC breaks are set before or after an
instruction is executed.
4. When a break condition is satisfied, a trigger signal is output from the UBCTRG pin.

7.4 Operation
7.4.1 Flow of the User Break Operation
The flow from setting of break conditions to user break interrupt exception handling is described
below:
1. The break address is set in a break address register (BAR). The masked address bits are set in a
break address mask register (BAMR). The bus break conditions are set in the break bus cycle
register (BBR). Three control bit groups of BBR (C bus cycle/I bus cycle select, instruction
fetch/data access select, and read/write select) are each set. No user break will be generated if
even one of these groups is set to 00. The relevant break control conditions are set in the bits of
the break control register (BRCR). Make sure to set all registers related to breaks before setting
BBR, and branch after reading from the last written register. The newly written register values
become valid from the instruction at the branch destination.
2. In the case where the break conditions are satisfied, the UBC sends a user break interrupt
request to the CPU, sets the C bus condition match flag (SCMFC) or I bus condition match
flag (SCMFD) for the appropriate channel, and outputs a pulse to the UBCTRG pin with the
width set by the CKS1 and CKS0 bits. Setting the UBID bit in BBR to 1 enables external
monitoring of the trigger output without requesting user break interrupts.
3. On receiving a user break interrupt request signal, the INTC determines its priority. Since the
user break interrupt has a priority level of 15, it is accepted when the priority level set in the
interrupt mask level bits (I3 to I0) of the status register (SR) is 14 or lower. If the I3 to I0 bits
are set to a priority level of 15, the user break interrupt is not accepted, but the conditions are
checked, and condition match flags are set if the conditions match. For details on ascertaining
the priority, see section 6, Interrupt Controller (INTC).
4. Condition match flags (SCMFC and SCMFD) can be used to check which condition has been
satisfied. They are set when the conditions match, but are not reset. To use these flags again,
write 0 to the corresponding bit of the flags.
5. It is possible that the breaks set in channels 0 to 3 occur around the same time. In this case,
there will be only one user break request to the CPU, but these four break channel match flags
may be set at the same time.
6. When selecting the I bus as the break condition, note as follows:
⎯ Several bus masters, including the CPU and DMAC, are connected to the I bus. The UBC
monitors bus cycles generated by the bus master specified by BBR, and determines the
condition match.
Section 7 User Break Controller (UBC)
Rev. 3.00 Mar. 04, 2009 Page 167 of 1168
REJ09B0344-0300
⎯ I bus cycles (including read fill cycles) resulting from instruction fetches on the C bus by
the CPU are defined as instruction fetch cycles on the I bus, while other bus cycles are
defined as data access cycles.
⎯ The DMAC only issues data access cycles for I bus cycles.
⎯ If a break condition is specified for the I bus, even when the condition matches in an I bus
cycle resulting from an instruction executed by the CPU, at which instruction the user
break is to be accepted cannot be clearly defined.
7.4.2 Break on Instruction Fetch Cycle
1. When C bus/instruction fetch/read/word or longword is set in the break bus cycle register
(BBR), the break condition is the FAB bus instruction fetch cycle. Whether PC breaks are set
before or after the execution of the instruction can then be selected with the PCB0 or PCB1 bit
of the break control register (BRCR) for the appropriate channel. If an instruction fetch cycle is
set as a break condition, clear LSB in the break address register (BAR) to 0. A break cannot be
generated as long as this bit is set to 1.
2. A break for instruction fetch which is set as a break before instruction execution occurs when it
is confirmed that the instruction has been fetched and will be executed. This means a break
does not occur for instructions fetched by overrun (instructions fetched at a branch or during
an interrupt transition, but not to be executed). When this kind of break is set for the delay slot
of a delayed branch instruction, the break is not generated until the execution of the first
instruction at the branch destination.
Note: If a branch does not occur at a delayed branch instruction, the subsequent instruction is
not recognized as a delay slot.
3. When setting a break condition for break after instruction execution, the instruction set with
the break condition is executed and then the break is generated prior to execution of the next
instruction. As with pre-execution breaks, a break does not occur with overrun fetch
instructions. When this kind of break is set for a delayed branch instruction and its delay slot,
the break is not generated until the first instruction at the branch destination.
4. When an instruction fetch cycle is set, the break data register (BDR) is ignored. Therefore,
break data cannot be set for the break of the instruction fetch cycle.
5. If the I bus is set for a break of an instruction fetch cycle, the setting is invalidated.

Rev. 3.00 Mar. 04, 2009 Page 168 of 1168
REJ09B0344-0300
7.4.3 Break on Data Access Cycle
1. If the C bus is specified as a break condition for data access break, condition comparison is
performed for the virtual address accessed by the executed instructions, and a break occurs if
the condition is satisfied. If the I bus is specified as a break condition, condition comparison is
performed for the physical address of the data access cycles that are issued by the bus master
specified by the bits to select the bus master of the I bus, and a break occurs if the condition is
satisfied. For details on the CPU bus cycles issued on the I bus, see 6 in section 7.4.1, Flow of
the User Break Operation.
2. The relationship between the data access cycle address and the comparison condition for each
operand size is listed in table 7.3.
Table 7.3 Data Access Cycle Addresses and Operand Size Comparison Conditions
Access Size Address Compared
Longword Compares break address register bits 31 to 2 to address bus bits 31 to 2
Word Compares break address register bits 31 to 1 to address bus bits 31 to 1
Byte Compares break address register bits 31 to 0 to address bus bits 31 to 0
This means that when address H'00001003 is set in the break address register (BAR), for
example, the bus cycle in which the break condition is satisfied is as follows (where other
conditions are met).
Longword access at H'00001000
Word access at H'00001002
Byte access at H'00001003
3. If the data access cycle is selected, the instruction at which the break will occur cannot be
determined.

7.4.4 Value of Saved Program Counter
When a break occurs, the address of the instruction from where execution is to be resumed is
saved to the stack, and the exception handling state is entered. If the C bus (FAB)/instruction fetch
cycle is specified as a break condition, the instruction at which the break should occur can be
uniquely determined. If the C bus/data access cycle or I bus/data access cycle is specified as a
break condition, the instruction at which the break should occur cannot be uniquely determined.
1. When C bus (FAB)/instruction fetch (before instruction execution) is specified as a break
condition:
The address of the instruction that matched the break condition is saved to the stack. The
instruction that matched the condition is not executed, and the break occurs before it. However
when a delay slot instruction matches the condition, the instruction is executed, and the branch
destination address is saved to the stack.
2. When C bus (FAB)/instruction fetch (after instruction execution) is specified as a break
condition:
The address of the instruction following the instruction that matched the break condition is
saved to the stack. The instruction that matches the condition is executed, and the break occurs
before the next instruction is executed. However when a delayed branch instruction or delay
slot matches the condition, the instruction is executed, and the branch destination address is
saved to the stack.
3. When C bus/data access cycle or I bus/data access cycle is specified as a break condition:
The address after executing several instructions of the instruction that matched the break
condition is saved to the stack.

REJ09B0344-0300
7.5 Usage Notes
1. The CPU can read from or write to the UBC registers via the I bus. Accordingly, during the
period from executing an instruction to rewrite the UBC register till the new value is actually
rewritten, the desired break may not occur. In order to know the timing when the UBC register
is changed, read from the last written register. Instructions after then are valid for the newly
written register value.
2. The UBC cannot monitor access to the C bus and I bus cycles in the same channel.
3. When a user break interrupt request and another exception source occur at the same
instruction, which has higher priority is determined according to the priority levels defined in
table 5.1 in section 5, Exception Handling. If an exception source with higher priority occurs,
the user break interrupt request is not received.
4. Note the following when a break occurs in a delay slot.
If a pre-execution break is set at a delay slot instruction, the user break interrupt request is not
received immediately before execution of the branch destination.
5. User breaks are disabled during UBC module standby mode. Do not read from or write to the
UBC registers during UBC module standby mode; the values are not guaranteed.
6. Do not set an address within an interrupt exception handling routine whose interrupt priority
level is at least 15 (including user break interrupts) as a break address.
7. Do not set break after instruction execution for the SLEEP instruction or for the delayed
branch instruction where the SLEEP instruction is placed at its delay slot.
8. When setting a break for a 32-bit instruction, set the address where the upper 16 bits are
placed. If the address of the lower 16 bits is set and a break before instruction execution is set
as a break condition, the break is handled as a break after instruction execution.
9. Do not set a user break before instruction execution for the instruction following the DIVU or
DIVS instruction. If a user break before instruction execution is set for the instruction
following the DIVU or DIVS instruction and an exception or interrupt occurs during execution
of the DIVU or DIVS instruction, a user break occurs before instruction execution even though
execution of the DIVU or DIVS instruction is halted.
10. Do not set a user break both before instruction execution and after instruction execution for
instruction of the same address. If, for example, a user break before instruction execution on
channel 0 and a user break after instruction on channel 1 are set at the instruction of the same
address, the condition match flag for the channel 1 is set even though a user break on channel 0
occurs before instruction execution.

⎯ Controls insertion of wait cycles for each address space.
⎯ Controls insertion of wait cycles for each read access and write access.
⎯ Can set independent idle cycles during the continuous access for five cases: read-write (in
same space/different spaces), read-read (in same space/different spaces), the first cycle is a
write access.
2. Normal space interface
⎯ Supports the interface that can directly connect to the SRAM.
3. Burst ROM interface (clock asynchronous)
⎯ High-speed access to the ROM that has the page mode function.
4. MPX-I/O interface
⎯ Can directly connect to a peripheral LSI that needs an address/data multiplexing.
5. SDRAM interface
⎯ Can set the SDRAM in up to two areas.
⎯ Multiplex output for row address/column address.
⎯ Efficient access by single read/single write.
⎯ High-speed access in bank-active mode.
⎯ Supports an auto-refresh and self-refresh.
⎯ Supports low-frequency and power-down modes.
⎯ Issues MRS and EMRS commands.

Rev. 3.00 Mar. 04, 2009 Page 176 of 1168
REJ09B0344-0300
6. SRAM interface with byte selection
⎯ Can connect directly to a SRAM with byte selection.
7. Burst ROM interface (clock synchronous)
⎯ Can connect directly to a ROM of the clock-synchronous type.
8. Bus arbitration
⎯ Shares all of the resources with other CPU and outputs the bus enable after receiving the
bus request from external devices.
9. Refresh function
⎯ Supports the auto-refresh and self-refresh functions.
⎯ Specifies the refresh interval using the refresh counter and clock selection.
⎯ Can execute concentrated refresh by specifying the refresh counts (1, 2, 4, 6, or 8).
10. Usage as interval timer for refresh counter
⎯ Generates an interrupt request at compare match.

8.3.2 Setting Operating Modes
This LSI can set the following modes of operation at the time of power-on reset using the external
pins.
• Single-Chip Mode
In single-chip mode, no access is made to the external bus, and the LSI is activated by the on-
chip ROM program upon a power-on reset. The BSC module enters the module standby state
to reduce power consumption.
• On-Chip ROM-Enabled Mode/On-Chip ROM-Disabled Mode
In on-chip ROM-enabled mode, since the first half of area 0 is allocated to the on-chip ROM,
the LSI can be activated by the on-chip ROM program upon a power-on reset. The second half
of area 0 is the external memory space.
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 181 of 1168
REJ09B0344-0300
In on-chip ROM-disabled mode, the LSI is activated by the program stored in the external
memory allocated to area 0. The second half of area 0 is the external memory space. In this
case, a ROM is assumed for the external memory of area 0. Therefore, minimum functions are
provided for the pins including address bus, data bus, CS0, and RD. Although BS, RDWR,
WEn, and other pins are shown in the examples of access waveforms in this section, these are
examples when pin settings are performed by the pin function controller. For details, see
section 19, Pin Function Controller (PFC). Do not perform any operation except for area 0 read
access until the pin settings by the program is completed.
• Initial Settings of Data Bus Widths for Areas 0 to 7
The initial settings of data bus widths of areas 0 to 7 can be selected at a time as 8 or 16 bits.
In on-chip ROM-disabled mode, the data bus width of area 0 cannot be changed from its initial
setting after a power-on reset, but the data bus widths of areas 1 to 7 can be changed by
register settings in the program. In on-chip ROM-enabled mode, all the data bus widths of
areas 0 to 7 can be changed by register settings in the program. Note that data bus widths will
be restricted depending on memory types.
• Initial Settings of Endianness
The initial settings of byte-data alignment of areas 0 to 7 can be selected as big endian or little
endian. In on-chip ROM-disabled mode, the endianness of area 0 cannot be changed from its
initial setting after a power-on reset, but the endianness of areas 1 to 7 can be changed by
register settings in the program. In on-chip ROM-enabled mode, all the endianness of areas 0
to 7 can be changed by register settings in the program. Little endian cannot be selected in area
0. Since both 32-bit and 16-bit accesses are included in instruction fetches, no instructions can
be assigned in little endian area. Accordingly, instructions should be executed in big endian
area.
For details of mode settings, see section 3, MCU Operating Modes.

8.4.2 CSn Space Bus Control Register (CSnBCR) (n = 0 to 7)
CSnBCR is a 32-bit readable/writable register that specifies the type of memory connected to a
space, data bus width of an area, endian, and the number of waits between access cycles. This
register is initialized to H'36DB0x00 by a power-on reset and retains the value by a manual reset
and in software standby mode.
Do not access external memory other than area 0 until CSnBCR initial setting is completed.
Idle cycles may be inserted even when they are not specified. For details, see section 8.5.10, Wait
between Access Cycles.

RTCSR specifies various items about refresh for SDRAM. RTCSR is initialized to H'00000000 by
a power-on reset and retains the value by a manual reset and in software standby mode.
When RTCSR is written, the upper 16 bits of the write data must be H'A55A to cancel write
protection.
The phase of the clock for incrementing the count in the refresh timer counter (RTCNT) is
adjusted only by a power-on reset. Note that there is an error in the time until the compare match
flag is set for the first time after the timer is started with the CKS[2:0] bits being set to a value
other than B'000.

8.4.7 Refresh Time Constant Register (RTCOR)
RTCOR is an 8-bit register. When RTCOR matches RTCNT, the CMF bit in RTCSR is set to 1
and RTCNT is cleared to 0.
When the RFSH bit in SDCR is 1, a memory refresh request is issued by this matching signal.
This request is maintained until the refresh operation is performed. If the request is not processed
when the next matching occurs, the previous request is ignored.
The REFOUT signal can be asserted when a refresh request is generated while the bus is released.
For details, see the description of Relationship between Refresh Requests and Bus Cycles in
section 8.5.6 (9), Relationship between Refresh Requests and Bus Cycles, and section 8.5.11, Bus
Arbitration.
When the CMIE bit in RTCSR is set to 1, an interrupt request is issued by this matching signal.
The request continues to be output until the CMF bit in RTCSR is cleared. Clearing the CMF bit
only affects the interrupt request and does not clear the refresh request. Therefore, a combination
of refresh request and interval timer interrupt can be specified so that the number of refresh
requests are counted by using timer interrupts while refresh is performed periodically.
When RTCOR is written, the upper 16 bits of the write data must be H'A55A to cancel write
protection. This register is initialized to H'00000000 by a power-on reset and retains the value by a
manual reset and in software standby mode.

8.5 Operation
8.5.1 Endian/Access Size and Data Alignment
This LSI supports big endian in which the 0 address is the most significant byte (MSB), and little
endian in which the 0 address is the least significant byte (LSB) in the byte data. In a space of
areas 1 to 7, endian can be set by the CSnBCR setting while the target space is not accessed. In a
space of area 0, the CSnBCR setting is invalid in on-chip ROM-disabled mode. In on-chip ROM-
enabled mode, endian can be set by the CSnBCR setting in a space of areas 0 to 7.
Two data bus widths (8 bits and 16 bits) are available for normal memory and SRAM with byte
selection. Only 16-bit data bus width is available for SDRAM. For MPX-I/O, the data bus width is
fixed at 8 bits or 16 bits, or 8 bits or 16 bits can be selected by the access address. Data alignment
is performed in accordance with the data bus width of the device. This also means that when
longword data is read from a byte-width device, the read operation must be done four times. In
this LSI, data alignment and conversion of data length is performed automatically between the
respective interfaces.
Tables 8.5 to 8.8 show the relationship between device data width and access unit. Note that
addresses corresponding to the strobe signals for the 16-bit bus width differ between big endian
and little endian. WE1 indicates the 0 address in big-endian mode, but WE0 indicates the 0
address in little-endian mode.

8.5.2 Normal Space Interface
(1) Basic Timing
For access to a normal space, this LSI uses strobe signal output in consideration of the fact that
mainly static RAM will be directly connected. When using SRAM with a byte-selection pin, see
section 8.5.8, SRAM Interface with Byte Selection. Figure 8.2 shows the basic timings of normal
space access. A no-wait normal access is completed in two cycles. The BS signal is asserted for
one cycle to indicate the start of a bus cycle.

There is no access size specification when reading. The correct access start address is output in the
least significant bit of the address, but since there is no access size specification, 16 bits are always

read in case of a 16-bit device. When writing, only the WEn signal for the byte to be written is
asserted.
It is necessary to output the data that has been read using RD when a buffer is established in the
data bus. The RD/WR signal is in a read state (high output) when no access has been carried out.
Therefore, care must be taken when controlling the external data buffer, to avoid collision.
Figures 8.3 and 8.4 show the basic timings of normal space access. If the WM bit in CSnWCR is
cleared to 0, a Tnop cycle is inserted after the CSn space access to evaluate the external wait
(figure 8.3). If the WM bit in CSnWCR is set to 1, external waits are ignored and no Tnop cycle is
inserted (figure 8.4).

8.5.3 Access Wait Control
Wait cycle insertion on a normal space access can be controlled by the settings of bits WR3 to
WR0 in CSnWCR. It is possible for areas 1, 4, 5, and 7 to insert wait cycles independently in read
access and in write access. Areas 0, 2, 3, and 6 have common access wait for read cycle and write
cycle. The specified number of Tw cycles are inserted as wait cycles in a normal space access
shown in figure 8.7.

8.5.4 CSn Assert Period Expansion
The number of cycles from CSn assertion to RD, WEn assertion can be specified by setting bits
SW1 and SW0 in CSnWCR. The number of cycles from RD, WEn negation to CSn negation can
be specified by setting bits HW1 and HW0. Therefore, a flexible interface to an external device
can be obtained. Figure 8.9 shows an example. A Th cycle and a Tf cycle are added before and
after an ordinary cycle, respectively. In these cycles, RD and WEn are not asserted, while other
signals are asserted. The data output is prolonged to the Tf cycle, and this prolongation is useful
for devices with slow writing operations.

signals control the accessing. The basic access for the MPX space consists of 2 cycles of address
output followed by an access to a normal space. The bus width for the address output cycle or the
data input/output cycle is fixed to 8 bits or 16 bits. Alternatively, it can be 8 bits or 16 bits
depending on the address to be accessed.
Output of the addresses D15 to D0 or D7 to D0 is performed from cycle Ta2 to cycle Ta3.
Because cycle Ta1 has a high-impedance state, collisions of addresses and data can be avoided
without inserting idle cycles, even in continuous access cycles. Address output is increased to 3
cycles by setting the MPXW bit in CS5WCR to 1.
The RD/WR signal is output at the same time as the CS5 signal; it is high in the read cycle and
low in the write cycle.
The data cycle is the same as that in a normal space access.
Timing charts are shown in figures 8.10 to 8.12.

8.5.6 SDRAM Interface
(1) SDRAM Direct Connection
The SDRAM that can be connected to this LSI is a product that has 11/12/13 bits of row address,
8/9/10 bits of column address, 4 or less banks, and uses the A10 pin for setting precharge mode in
read and write command cycles.
The control signals for direct connection of SDRAM are RASL, CASL, RD/WR, DQMUL,
DQMLL, CKE, CS2, and CS3. All the signals other than CS2 and CS3 are common to all areas,
and signals other than CKE are valid when CS2 or CS3 is asserted. SDRAM can be connected to
up to 2 spaces. The data bus width of the area that is connected to SDRAM can be set to 16 bits
only.
Burst read/single write (burst length 1) and burst read/burst write (burst length 1) are supported as
SDRAM operating mode.
Commands for SDRAM can be specified by RASL, CASL, RD/WR, and specific address signals.
These commands supports:
• NOP
• Auto-refresh (REF)
• Self-refresh (SELF)
• All banks pre-charge (PALL)
• Specified bank pre-charge (PRE)
• Bank active (ACTV)
• Read (READ)
• Read with pre-charge (READA)
• Write (WRIT)
• Write with pre-charge (WRITA)
• Write mode register (MRS, EMRS)
The byte to be accessed is specified by DQMUL and DQMLL. Reading or writing is performed
for a byte whose corresponding DQMxx is low. For details on the relationship between DQMxx
and the byte to be accessed, see section 8.5.1, Endian/Access Size and Data Alignment.
Figure 8.13 shows an example of the connection of the SDRAM with the LSI.

(2) Address Multiplexing
An address multiplexing is specified so that SDRAM can be connected without external
multiplexing circuitry according to the setting of bits BSZ[1:0] in CSnBCR, bits A2ROW[1:0],
and A2COL[1:0], A3ROW[1:0], and A3COL[1:0] in SDCR. Tables 8.9 to 8.11 show the
relationship between the settings of bits BSZ[1:0], A2ROW[1:0], A2COL[1:0], A3ROW[1:0], and
A3COL[1:0] and the bits output at the address pins. Do not specify those bits in the manner other
than this table, otherwise the operation of this LSI is not guaranteed. A29 to A18 are not
multiplexed and the original values of address are always output at these pins.
The A0 pin of SDRAM specifies a word address. Therefore, connect the A0 pin of SDRAM to the
A1 pin of the LSI; then connect the A1 pin of SDRAM to the A2 pin of the LSI, and so on.

(3) Burst Read
A burst read occurs in the following cases with this LSI.
• Access size in reading is larger than data bus width.
• 16-byte transfer in DMAC
This LSI always accesses the SDRAM with burst length 1. For example, read access of burst
length 1 is performed consecutively 8 times to read 16-byte continuous data from the SDRAM that
is connected to a 16-bit data bus. This access is called the burst read with the burst number 8.
Table 8.12 shows the relationship between the access size and the number of bursts.
Table 8.12 Relationship between Access Size and Number of Bursts
Bus Width Access Size Number of Bursts
16 bits 8 bits 1
16 bits 1
32 bits 2
16 bits 8
Figures 8.14 and 8.15 show a timing chart in burst read. In burst read, an ACTV command is
output in the Tr cycle, the READ command is issued in the Tc1, Tc2, and Tc3 cycles, the READA
command is issued in the Tc4 cycle, and the read data is received at the rising edge of the external
clock (CK) in the Td1 to Td4 cycles. The Tap cycle is used to wait for the completion of an auto-
precharge induced by the READA command in the SDRAM. In the Tap cycle, a new command
will not be issued to the same bank. However, access to another CS space or another bank in the
same SDRAM space is enabled. The number of Tap cycles is specified by the WTRP1 and
WTRP0 bits in CS3WCR.
In this LSI, wait cycles can be inserted by specifying each bit in CS3WCR to connect the SDRAM
in variable frequencies. Figure 8.15 shows an example in which wait cycles are inserted. The
number of cycles from the Tr cycle where the ACTV command is output to the Tc1 cycle where
the READ command is output can be specified using the WTRCD1 and WTRCD0 bits in
CS3WCR. If the WTRCD1 and WTRCD0 bits specify one cycles or more, a Trw cycle where the
NOT command is issued is inserted between the Tr cycle and Tc1 cycle. The number of cycles
from the Tc1 cycle where the READ command is output to the Td1 cycle where the read data is
latched can be specified for the CS2 and CS3 spaces independently, using the A2CL1 and A2CL0
bits in CS2WCR or the A3CL1 and A3CL0 bits in CS3WCR and WTRCD0 bit in CS3WCR. The
number of cycles from Tc1 to Td1 corresponds to the SDRAM CAS latency. The CAS latency for
the SDRAM is normally defined as up to three cycles. However, the CAS latency in this LSI can
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 252 of 1168
REJ09B0344-0300
be specified as 1 to 4 cycles. This CAS latency can be achieved by connecting a latch circuit
between this LSI and the SDRAM.
A Tde cycle is an idle cycle required to transfer the read data into this LSI and occurs once for
every burst read or every single read.

(4) Single Read
A read access ends in one cycle when the data bus width is larger than or equal to the access size.
This, simply stated, is single read. As the SDRAM is set to the burst read with the burst length 1,
only the required data is output. A read access that ends in one cycle is called single read.

(5) Burst Write
A burst write occurs in the following cases in this LSI.
• Access size in writing is larger than data bus width.
• 16-byte transfer in DMAC
This LSI always accesses SDRAM with burst length 1. For example, write access of burst length 1
is performed continuously 8 times to write 16-byte continuous data to the SDRAM that is
connected to a 16-bit data bus. This access is called burst write with the burst number 8.
The relationship between the access size and the number of bursts is shown in table 8.12.
Figure 8.17 shows a timing chart for burst writes. In burst write, an ACTV command is output in
the Tr cycle, the WRIT command is issued in the Tc1, Tc2, and Tc3 cycles, and the WRITA
command is issued to execute an auto-precharge in the Tc4 cycle. In the write cycle, the write data
is output simultaneously with the write command. After the write command with the auto-
precharge is output, the Trw1 cycle that waits for the auto-precharge initiation is followed by the
Tap cycle that waits for completion of the auto-precharge induced by the WRITA command in the
SDRAM. Between the Trwl and the Tap cycle, a new command will not be issued to the same
bank. However, access to another CS space or another bank in the same SDRAM space is enabled.
The number of Trw1 cycles is specified by the TRWL1 and TRWL0 bits in CS3WCR. The
number of Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR.

(6) Single Write
A write access ends in one cycle when the data bus width is larger than or equal to access size. As
a single write or burst write with burst length 1 is set in SDRAM, only the required data is output.
The write access that ends in one cycle is called single write. Figure 8.18 shows the single write

(7) Bank Active
The SDRAM bank function can be used to support high-speed access to the same row address.
When the BACTV bit in SDCR is 1, access is performed using commands without auto-precharge
(READ or WRIT). This function is called bank-active function. This function is valid only for
either the upper or lower bits of area 3. When area 3 is set to bank-active mode, area 2 should be
set to normal space or SRAM with byte selection. When areas 2 and 3 are both set to SDRAM or
both the upper and lower bits of area 3 are connected to SDRAM, auto-precharge mode must be
set.
When the bank-active function is used, precharging is not performed when the access ends. When
accessing the same row address in the same bank, it is possible to issue the READ or WRIT
command immediately, without issuing an ACTV command. As SDRAM is internally divided
into several banks, it is possible to activate one row address in each bank. If the next access is to a
different row address, a PRE command is first issued to precharge the relevant bank, then when
precharging is completed, the access is performed by issuing an ACTV command followed by a
READ or WRIT command. If this is followed by an access to a different row address, the access
time will be longer because of the precharging performed after the access request is issued. The
number of cycles between issuance of the PRE command and the ACTV command is determined
by the WTRP1 and WTPR0 bits in CS3WCR.
In a write, when an auto-precharge is performed, a command cannot be issued to the same bank
for a period of Trwl + Tap cycles after issuance of the WRITA command. When bank active mode
is used, READ or WRIT commands can be issued successively if the row address is the same. The
number of cycles can thus be reduced by Trwl + Tap cycles for each write.
There is a limit on tRAS, the time for placing each bank in the active state. If there is no guarantee
that there will not be a cache hit and another row address will be accessed within the period in
which this value is maintained by program execution, it is necessary to set auto-refresh and set the
refresh cycle to no more than the maximum value of tRAS.
A burst read cycle without auto-precharge is shown in figure 8.19, a burst read cycle for the same
row address in figure 8.20, and a burst read cycle for different row addresses in figure 8.21.
Similarly, a burst write cycle without auto-precharge is shown in figure 8.22, a burst write cycle
for the same row address in figure 8.23, and a burst write cycle for different row addresses in
figure 8.24.
In figure 8.20, a Tnop cycle in which no operation is performed is inserted before the Tc cycle that
issues the READ command. The Tnop cycle is inserted to acquire two cycles of CAS latency for
the DQMxx signal that specifies the read byte in the data read from the SDRAM. If the CAS

REJ09B0344-0300
latency is specified as two cycles or more, the Tnop cycle is not inserted because the two cycles of
latency can be acquired even if the DQMxx signal is asserted after the Tc cycle.
When bank active mode is set, if only access cycles to the respective banks in the area 3 space are
considered, as long as access cycles to the same row address continue, the operation starts with the
cycle in figure 8.19 or 8.23, followed by repetition of the cycle in figure 8.20 or 8.23. An access to
a different area during this time has no effect. If there is an access to a different row address in the
bank active state, after this is detected the bus cycle in figure 8.20 or 8.23 is executed instead of
that in figure 8.21 or 8.24. In bank active mode, too, all banks become inactive after a refresh
cycle or after the bus is released as the result of bus arbitration.

(8) Refreshing
This LSI has a function for controlling SDRAM refreshing. Auto-refreshing can be performed by
clearing the RMODE bit to 0 and setting the RFSH bit to 1 in SDCR. A continuous refreshing can
be performed by setting the RRC2 to RRC0 bits in RTCSR. If SDRAM is not accessed for a long
period, self-refresh mode, in which the power consumption for data retention is low, can be
activated by setting both the RMODE bit and the RFSH bit to 1.
(a) Auto-refreshing
Refreshing is performed at intervals determined by the input clock selected by bits CKS2 to CKS0
in RTCSR, and the value set by in RTCOR. The value of bits CKS2 to CKS0 in RTCOR should
be set so as to satisfy the refresh interval stipulation for the SDRAM used. First make the settings
for RTCOR, RTCNT, and the RMODE and RFSH bits in SDCR, then make the CKS2 to CKS0
and RRC2 to RRC0 settings. When the clock is selected by bits CKS2 to CKS0, RTCNT starts
counting up from the value at that time. The RTCNT value is constantly compared with the
RTCOR value, and if the two values are the same, a refresh request is generated and an auto-
refresh is performed for the number of times specified by the RRC2 to RRC0. At the same time,
RTCNT is cleared to zero and the count-up is restarted.
Figure 8.25 shows the auto-refresh cycle timing. After starting, the auto refreshing, PALL
command is issued in the Tp cycle to make all the banks to pre-charged state from active state
when some bank is being pre-charged. Then REF command is issued in the Trr cycle after
inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR. A
new command is not issued for the duration of the number of cycles specified by the WTRC1 and
WTRC0 bits in CS3WCR after the Trr cycle. The WTRC1 and WTRC0 bits must be set so as to
satisfy the SDRAM refreshing cycle time stipulation (tRC). An idle cycle is inserted between the
Tp cycle and Trr cycle when the setting value of the WTRP1 and WTRP0 bits in CS3WCR is
longer than or equal to 1 cycle.

REJ09B0344-0300
(b) Self-refreshing
Self-refresh mode in which the refresh timing and refresh addresses are generated within the
SDRAM. Self-refreshing is activated by setting both the RMODE bit and the RFSH bit in SDCR
to 1. After starting the self-refreshing, PALL command is issued in Tp cycle after the completion
of the pre-charging bank. A SELF command is then issued after inserting idle cycles of which
number is specified by the WTRP1 and WTRP0 bits in CS3WSR. SDRAM cannot be accessed
while in the self-refresh state. Self-refresh mode is cleared by clearing the RMODE bit to 0. After
self-refresh mode has been cleared, command issuance is disabled for the number of cycles
specified by the WTRC1 and WTRC0 bits in CS3WCR.
Self-refresh timing is shown in figure 8.26. Settings must be made so that self-refresh clearing and
data retention are performed correctly, and auto-refreshing is performed at the correct intervals.
When self-refreshing is activated from the state in which auto-refreshing is set, or when exiting
standby mode other than through a power-on reset, auto-refreshing is restarted if the RFSH bit is
set to 1 and the RMODE bit is cleared to 0 when self-refresh mode is cleared. If the transition
from clearing of self-refresh mode to the start of auto-refreshing takes time, this time should be
taken into consideration when setting the initial value of RTCNT. Making the RTCNT value 1 less
than the RTCOR value will enable refreshing to be started immediately.
After self-refreshing has been set, the self-refresh state continues even if the chip standby state is
entered using the LSI standby function, and is maintained even after recovery from standby mode
due to an interrupt. Note that the necessary signals such as CKE must be driven even in standby
state by setting the HIZCNT bit in CMNCR to 1.
The self-refresh state is not cleared by a manual reset. In case of a power-on reset, the bus state
controller's registers are initialized, and therefore the self-refresh state is cleared.

(9) Relationship between Refresh Requests and Bus Cycles
If a refresh request occurs during bus cycle execution, the refresh cycle must wait for the bus cycle
to be completed. If a refresh request occurs while the bus is released by the bus arbitration
function, the refresh will not be executed until the bus mastership is acquired. This LSI has the
REFOUT pin to request the bus while waiting for refresh execution. For REFOUT pin function
selection, see section 19, Pin Function Controller (PFC). This LSI continues to assert REFOUT
(low level) until the bus is acquired.
On receiving the asserted REFOUT signal, the external device must negate the BREQ signal and
return the bus. If the external bus does not return the bus for a period longer than the specified
refresh interval, refresh cannot be executed and the SDRAM contents may be lost.
If a new refresh request occurs while waiting for the previous refresh request, the previous refresh
request is deleted. To refresh correctly, a bus cycle longer than the refresh interval or the bus
mastership occupation must be prevented from occurring.
If a bus mastership is requested during self-refresh, the bus will not be released until the refresh is
completed.

(10) Low-Frequency Mode
When the SLOW bit in SDCR is set to 1, output of commands, addresses, and write data, and
fetch of read data are performed at a timing suitable for operating SDRAM at a low frequency.
Figure 8.27 shows the access timing in low-frequency mode. In this mode, commands, addresses,
and write data are output in synchronization with the falling edge of CK, which is half a cycle
delayed than the normal timing. Read data is fetched at the rising edge of CK, which is half a
cycle faster than the normal timing. This timing allows the hold time of commands, addresses,
write data, and read data to be extended.
If SDRAM is operated at a high frequency with the SLOW bit set to 1, the setup time of
commands, addresses, write data, and read data are not guaranteed. Take the operating frequency
and timing design into consideration when making the SLOW bit setting.

(11) Power-Down Mode
If the PDOWN bit in SDCR is set to 1, the SDRAM is placed in power-down mode by bringing
the CKE signal to the low level in the non-access cycle. This power-down mode can effectively
lower the power consumption in the non-access cycle. However, please note that if an access
occurs in power-down mode, a cycle of overhead occurs because a cycle is needed to assert the
CKE in order to cancel power-down mode.

(12) Power-On Sequence
In order to use SDRAM, mode setting must first be made for SDRAM after waiting for 100 μs or
a longer period after powering on. This 100-μs or longer period should be obtained by a power-on
reset generating circuit or software.
To perform SDRAM initialization correctly, the bus state controller registers must first be set,
followed by a write to the SDRAM mode register. In SDRAM mode register setting, the address
signal value at that time is latched by a combination of the CSn, RASL, CASL, and RD/WR
signals. If the value to be set is X, the bus state controller provides for value X to be written to the
SDRAM mode register by performing a write to address H'FFFC4000 + X for area 2 SDRAM,
and to address H'FFFC5000 + X for area 3 SDRAM. In this operation the data is ignored, but the
mode write is performed as a byte-size access. To set burst read/single write, CAS latency 2 to 3,
wrap type = sequential, and burst length 1 supported by the LSI, arbitrary data is written in a byte-
size access to the addresses shown in table 8.13. In this time 0 is output at the external address
pins of A12 or later.

Mode register setting timing is shown in figure 8.29. A PALL command (all bank pre-charge
command) is firstly issued. A REF command (auto refresh command) is then issued 8 times. An
MRS command (mode register write command) is finally issued. Idle cycles, of which number is
specified by the WTRP1 and WTRP0 bits in CS3WCR, are inserted between the PALL and the
first REF. Idle cycles, of which number is specified by the WTRC1 and WTRC0 bits in CS3WCR,
are inserted between REF and REF, and between the 8th REF and MRS. Idle cycles, of which
number is one or more, are inserted between the MRS and a command to be issued next.
It is necessary to keep idle time of certain cycles for SDRAM before issuing PALL command after
power-on. Refer to the manual of the SDRAM for the idle time to be needed. When the pulse
width of the reset signal is longer than the idle time, mode register setting can be started
immediately after the reset, but care should be taken when the pulse width of the reset signal is
shorter than the idle time.

(13) Low-Power SDRAM
The low-power SDRAM can be accessed using the same protocol as the normal SDRAM.
The differences between the low-power SDRAM and normal SDRAM are that partial refresh
takes place that puts only a part of the SDRAM in the self-refresh state during the self-refresh
function, and that power consumption is low during refresh under user conditions such as the
operating temperature. The partial refresh is effective in systems in which there is data in a work
area other than the specific area can be lost without severe repercussions.
The low-power SDRAM supports the extension mode register (EMRS) in addition to the mode
registers as the normal SDRAM. This LSI supports issuing of the EMRS command.
The EMRS command is issued according to the conditions specified in table below. For example,
if data H'0YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued
to the CS3 space in the following sequence: PALL -> REF × 8 -> MRS -> EMRS. In this case, the
MRS and EMRS issue addresses are H'0000XX0 and H'YYYYYYY, respectively. If data
H'1YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the
CS3 space in the following sequence: PALL -> MRS -> EMRS.

• Deep power-down mode
The low-power SDRAM supports deep power-down mode as a low-power consumption mode.
In the partial self-refresh function, self-refresh is performed on a specific area. In deep power-
down mode, self-refresh will not be performed on any memory area. This mode is effective in
systems where all of the system memory areas are used as work areas.
If the RMODE bit in the SDCR is set to 1 while the DEEP and RFSH bits in the SDCR are set to
1, the low-power SDRAM enters deep power-down mode. If the RMODE bit is cleared to 0, the
CKE signal is pulled high to cancel deep power-down mode. Before executing an access after
returning from deep power-down mode, the power-up sequence must be re-executed.

8.5.7 Burst ROM (Clock Asynchronous) Interface
The burst ROM (clock asynchronous) interface is used to access a memory with a high-speed read
function using a method of address switching called burst mode or page mode. In a burst ROM
(clock asynchronous) interface, basically the same access as the normal space is performed, but
the 2nd and subsequent access cycles are performed only by changing the address, without
negating the RD signal at the end of the 1st cycle. In the 2nd and subsequent access cycles,
addresses are changed at the falling edge of the CK.
For the 1st access cycle, the number of wait cycles specified by the W3 to W0 bits in CSnWCR is
inserted. For the 2nd and subsequent access cycles, the number of wait cycles specified by the W1
to W0 bits in CSnWCR is inserted.
In the access to the burst ROM (clock asynchronous), the BS signal is asserted only to the first
access cycle. An external wait input is valid only to the first access cycle.
In the single access or write access that does not perform the burst operation in the burst ROM
(clock asynchronous) interface, access timing is same as a normal space. In addition, there are
some restrictions on 16-byte write access. For details, see section 8.6, Usage Notes.
Table 8.15 lists a relationship between bus width, access size, and the number of bursts. Figure
8.32 shows a timing chart.

8.5.8 SRAM Interface with Byte Selection
The SRAM interface with byte selection is for access to an SRAM which has a byte-selection pin
(WEn). This interface has 16-bit data pins and accesses SRAMs having upper and lower byte
selection pins, such as UB and LB.
When the BAS bit in CSnWCR is cleared to 0 (initial value), the write access timing of the SRAM
interface with byte selection is the same as that for the normal space interface. While in read
access of a byte-selection SRAM interface, the byte-selection signal is output from the WEn pin,
which is different from that for the normal space interface. The basic access timing is shown in
figure 8.33. In write access, data is written to the memory according to the timing of the byte-
selection pin (WEn). For details, please refer to the Data Sheet for the corresponding memory.
If the BAS bit in CSnWCR is set to 1, the WEn pin and RD/WR pin timings change. Figure 8.34
shows the basic access timing. In write access, data is written to the memory according to the
timing of the write enable pin (RD/WR). The data hold timing from RD/WR negation to data write
must be acquired by setting the HW1 and HW0 bits in CSnWCR. Figure 8.35 shows the access
timing when a software wait is specified.

8.5.9 Burst ROM (Clock Synchronous) Interface
The burst ROM (clock synchronous) interface is supported to access a ROM with a synchronous
burst function at high speed. The burst ROM interface accesses the burst ROM in the same way as
a normal space. This interface is valid only for area 0.
In the first access cycle, wait cycles are inserted. In this case, the number of wait cycles to be
inserted is specified by the W3 to W0 bits in CS0WCR. In the second and subsequent cycles, the
number of wait cycles to be inserted is specified by the BW1 and BW0 bits in CS0WCR.
While the burst ROM (clock synchronous) is accessed, the BS signal is asserted only for the first
access cycle and an external wait input is also valid for the first access cycle.
If the bus width is 16 bits, the burst length must be specified as 8. The burst ROM interface does
not support the 8-bit bus width for the burst ROM.
The burst ROM interface performs burst operations for all read access. For example, in a
longword access over a 16-bit bus, valid 16-bit data is read two times and invalid 16-bit data is
read six times. These invalid data read cycles increase the memory access time and degrade the
program execution speed and DMA transfer speed. To prevent this problem, using 16-byte read by
the DMA is recommended. The burst ROM interface performs write access in the same way as
normal space access.

8.5.10 Wait between Access Cycles
As the operating frequency of LSIs becomes higher, the off-operation of the data buffer often
collides with the next data access when the read operation from devices with slow access speed is
completed. As a result of these collisions, the reliability of the device is low and malfunctions may
occur. A function that avoids data collisions by inserting idle (wait) cycles between continuous
access cycles has been newly added.
The number of wait cycles between access cycles can be set by the WM bit in CSnWCR, bits
IWW2 to IWW0, IWRWD2 to IWRWD0, IWRWS2 to IWRWS0, IWRRD2 to IWRRD0, and
IWRRS2 to IWRRS 0 in CSnBCR, and bits DMAIW2 to DMAIW0 and DMAIWA in CMNCR.
The conditions for setting the idle cycles between access cycles are shown below.
1. Continuous access cycles are write-read or write-write
2. Continuous access cycles are read-write for different spaces
3. Continuous access cycles are read-write for the same space
4. Continuous access cycles are read-read for different spaces
5. Continuous access cycles are read-read for the same space
6. Data output from an external device caused by DMA single address transfer is followed by
data output from another device that includes this LSI (DMAIWA = 0)
7. Data output from an external device caused by DMA single address transfer is followed by any
type of access (DMAIWA = 1)
For the specification of the number of idle cycles between access cycles described above, refer to
the description of each register.
Besides the idle cycles between access cycles specified by the registers, idle cycles must be
inserted to interface with the internal bus or to obtain the minimum pulse width for a multiplexed
pin (WEn). The following gives detailed information about the idle cycles and describes how to
estimate the number of idle cycles.
The number of idle cycles on the external bus from CSn negation to CSn or CSm assertion is
described below.
There are eight conditions that determine the number of idle cycles on the external bus as shown
in table 8.16. The effects of these conditions are shown in figure 8.38.
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 287 of 1168
REJ09B0344-0300
Table 8.16 Conditions for Determining Number of Idle Cycles
No. Condition Description Range Note
(1) DMAIW[2:0] in
CMNCR
These bits specify the number of
idle cycles for DMA single address
transfer. This condition is effective
only for single address transfer and
generates idle cycles after the
access is completed.
0 to 12 When 0 is specified for the
number of idle cycles, the
DACK signal may be asserted
continuously. This causes a
discrepancy between the
number of cycles detected by
the device with DACK and the
DMAC transfer count,
resulting in a malfunction.
(2) IW***[2:0] in
CSnBCR
These bits specify the number of
idle cycles for access other than
single address transfer. The
number of idle cycles can be
specified independently for each
combination of the previous and
next cycles. For example, in the
case where reading CS1 space
followed by reading other CS
space, the bits IWRRD[2:0] in
CS1BCR should be set to B'100 to
specify six or more idle cycles. This
condition is effective only for access
cycles other than single address
transfer and generates idle cycles
after the access is completed.
0 to 12 Do not set 0 for the number of
idle cycles between memory
types which are not allowed
to be accessed successively.
(3) SDRAM-related
bits in
CSnWCR
These bits specify precharge
completion and startup wait cycles
and idle cycles between commands
for SDRAM access. This condition
is effective only for SDRAM access
and generates idle cycles after the
access is completed
0 to 3 Specify these bits in
accordance with the
specification of the target
SDRAM.
(4) WM in
CSnWCR
This bit enables or disables external
WAIT pin input for the memory
types other than SDRAM. When
this bit is cleared to 0 (external
WAIT enabled), one idle cycle is
inserted to check the external WAIT
pin input after the access is
completed. When this bit is set to 1
(disabled), no idle cycle is
generated.
0 or 1
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 288 of 1168
REJ09B0344-0300
No. Condition Description Range Note
(5) Read data
transfer cycle
One idle cycle is inserted after a
read access is completed. This idle
cycle is not generated for the first or
middle cycles in divided access
cycles. This is neither generated
when the HM[1:0] bits in CSnWCR
are not B'00.
0 or 1 One idle cycle is always
generated after a read cycle
with SDRAM interface.
(6) Internal bus
idle cycles, etc.
External bus access requests from
the CPU or DMAC and their results
are passed through the internal
bus. The external bus enters idle
state during internal bus idle cycles
or while a bus other than the
external bus is being accessed.
This condition is not effective for
divided access cycles, which are
generated by the BSC when the
access size is larger than the
external data bus width.
0 or
larger
The number of internal bus
idle cycles may not become 0
depending on the Iφ:Bφ clock
ratio. Tables 8.17 and 8.18
show the relationship
between the clock ratio and
the minimum number of
internal bus idle cycles.
(7) Write data wait
cycles
During write access, a write cycle is
executed on the external bus only
after the write data becomes ready.
This write data wait period
generates idle cycles before the
write cycle. Note that when the
previous cycle is a write cycle and
the internal bus idle cycles are
shorter than the previous write
cycle, write data can be prepared in
parallel with the previous write cycle
and therefore, no idle cycle is
generated (write buffer effect).
0 or 1 For write → write or write →
read access cycles,
successive access cycles
without idle cycles are
frequently available due to
the write buffer effect
described in the left column. If
successive access cycles
without idle cycles are not
allowed, specify the minimum
number of idle cycles
between access cycles
through CSnBCR.
(8) Idle cycles
between
different
memory types
To ensure the minimum pulse width
on the signal-multiplexed pins, idle
cycles may be inserted before
access after memory types are
switched. For some memory types,
idle cycles are inserted even when
memory types are not switched.
0 to 2.5 The number of idle cycles
depends on the target
memory types. See table
8.19.

In the above conditions, a total of four conditions, that is, condition (1) or (2) (either one is
effective), condition (3) or (4) (either one is effective), a set of conditions (5) to (7) (these are
generated successively, and therefore the sum of them should be taken as one set of idle cycles),
and condition (8) are generated at the same time. The maximum number of idle cycles among
these four conditions become the number of idle cycles on the external bus. To ensure the
minimum idle cycles, be sure to make register settings for condition (1) or (2).

Figure 8.39 shows sample estimation of idle cycles between access cycles. In the actual operation,
the idle cycles may become shorter than the estimated value due to the write buffer effect or may
become longer due to internal bus idle cycles caused by stalling in the pipeline due to CPU
instruction execution or CPU register conflicts. Please consider these errors when estimating the
idle cycles.

8.5.11 Bus Arbitration
The bus arbitration of this LSI has the bus mastership in the normal state and releases the bus
mastership after receiving a bus request from another device.
Bus mastership is transferred at the boundary of bus cycles. Namely, bus mastership is released
immediately after receiving a bus request when a bus cycle is not being performed. The release of
bus mastership is delayed until the bus cycle is complete when a bus cycle is in progress. Even
when from outside the LSI it looks like a bus cycle is not being performed, a bus cycle may be
performing internally, started by inserting wait cycles between access cycles. Therefore, it cannot
be immediately determined whether or not bus mastership has been released by looking at the CSn
signal or other bus control signals. The states that do not allow bus mastership release are shown
below.
1. Between the read and write cycles of a TAS instruction, or 64-bit transfer cycle of an FMOV
instruction
2. Multiple bus cycles generated when the data bus width is smaller than the access size (for
example, between bus cycles when longword access is made to a memory with a data bus
width of 8 bits)
3. 16-byte transfer by the DMAC
4. Setting the BLOCK bit in CMNCR to 1
Moreover, by using DPRTY bit in CMNCR, whether the bus mastership request is received or not
can be selected during DMAC burst transfer.
The LSI has the bus mastership until a bus request is received from another device. Upon
acknowledging the assertion (low level) of the external bus request signal BREQ, the LSI releases
the bus at the completion of the current bus cycle and asserts the BACK signal. After the LSI
acknowledges the negation (high level) of the BREQ signal that indicates the external device has
released the bus, it negates the BACK signal and resumes the bus usage.
With the SDRAM interface, all bank pre-charge commands (PALLs) are issued when active banks
exist and the bus is released after completion of a PALL command.
The bus sequence is as follows. The address bus and data bus are placed in a high-impedance state
synchronized with the rising edge of CK. The bus mastership enable signal is asserted 0.5 cycles
after the above timing, synchronized with the falling edge of CK. The bus control signals (BS,
CSn, RASL, CASL, CKE, DQMxx, WEn, RD, and RD/WR) are placed in the high-impedance
state at subsequent rising edges of CK. Bus request signals are sampled at the falling edge of
CKIO. Note that CKE, RASL, and CASL can continue to be driven at the previous value even in
the bus-released state by setting the HIZCNT bit in CMNCR.
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 294 of 1168
REJ09B0344-0300
The sequence for reclaiming the bus mastership from an external device is described below. 1.5
cycles after the negation of BREQ is detected at the falling edge of CK, the bus control signals are
driven high. The bus acknowledge signal is negated at the next falling edge of the clock. The
fastest timing at which actual bus cycles can be resumed after bus control signal assertion is at the
rising edge of the CK where address and data signals are driven. Figure 8.40 shows the bus
arbitration timing.
When it is necessary to refresh SDRAM while releasing the bus mastership, the bus mastership
should be returned using the REFOUT signal. For details on the selection of REFOUT, see section
19, Pin Function Controller (PFC). The REFOUT signal is kept asserting at low level until the bus
mastership is acquired. The BREQ signal is negated by asserting the REFOUT signal and the bus
mastership is returned from the external device. If the bus mastership is not returned for a
refreshing period or longer, the contents of SDRAM cannot be guaranteed because a refreshing
cannot be executed.
While releasing the bus mastership, the SLEEP instruction (to enter sleep mode or standby mode),
as well as a manual reset, cannot be executed until the LSI obtains the bus mastership.
The BREQ input signal is ignored in standby mode and the BACK output signal is placed in the
high impedance state. If the bus mastership request is required in this state, the bus mastership
must be released by pulling down the BACK pin to enter standby mode.
The bus mastership release (BREQ signal for high level negation) after the bus mastership request
(BREQ signal for low level assertion) must be performed after the bus usage permission (BACK
signal for low level assertion). If the BREQ signal is negated before the BACK signal is asserted,
only one cycle of the BACK signal is asserted depending on the timing of the BREQ signal to be
negated and this may cause a bus contention between the external device and the LSI.

8.5.12 Others
(1) Reset
The bus state controller (BSC) can be initialized completely only at power-on reset. At power-on
reset, all signals are negated and data output buffers are turned off regardless of the bus cycle state
after the internal reset is synchronized with the internal clock. All control registers are initialized.
In standby, sleep, and manual reset, control registers of the bus state controller are not initialized.
At manual reset, only the current bus cycle being executed is completed. Since the RTCNT
continues counting up during manual reset signal assertion, a refresh request occurs to initiate the
refresh cycle.
(2) Access from the Side of the LSI Internal Bus Master
Since the bus state controller (BSC) incorporates a one-stage write buffer, the BSC can execute an
access via the internal bus before the previous external bus cycle is completed in a write cycle. If
the on-chip module is read or written after the external low-speed memory is written, the on-chip
module can be accessed before the completion of the external low-speed memory write cycle.
In read cycles, the CPU is placed in the wait state until read operation has been completed. To
continue the process after the data write to the device has been completed, perform a dummy read
to the same address to check for completion of the write before the next process to be executed.
The write buffer of the BSC functions in the same way for an access by a bus master other than
the CPU such as the DMAC. Accordingly, to perform dual address DMA transfers, the next read
cycle is initiated before the previous write cycle is completed. Note, however, that if both the
DMA source and destination addresses exist in external memory space, the next write cycle will
not be initiated until the previous write cycle is completed.
Changing the registers in the BSC while the write buffer is operating may disrupt correct write
access. Therefore, do not change the registers in the BSC immediately after a write access. If this
change becomes necessary, do it after executing a dummy read of the write data.
(3) On-Chip Peripheral Module Access
Access to the on-chip peripheral module registers from the internal bus requires 2 or more cycles
of the peripheral module clock (Pφ). When the CPU writes to an on-chip peripheral register,
however, the CPU can execute the following instructions without waiting for the register write to
complete.
This section describes the case where the system switches to software standby mode to reduce
power consumption as an example. In this case, the code sets the STBCR register STBY bit to 1
Section 8 Bus State Controller (BSC)
Rev. 3.00 Mar. 04, 2009 Page 296 of 1168
REJ09B0344-0300
and then executes a SLEEP instruction. The code must, however, perform a dummy read of the
STBCR register before executing the SLEEP instruction. If the dummy read is not performed, the
CPU will execute the SLEEP instruction before the STBY bit is set to 1, and the system will not
switch to the intended software standby mode, but rather will switch to sleep mode. The dummy
read of the STBCR register is required to wait for the write to the STBY bit to complete.
In other cases as well, application code should perform a dummy read of the same register after a
register write instruction and only then execute the following instructions for the intended purpose
to assure that the changes due to internal register writes are reflected when the following
instructions are executed as in this example.
The table below lists the number of access cycles required for CPU accesses to the on-chip
peripheral module registers.
Table 8.20 On-Chip Peripheral Module Register Access Cycle Counts
Access Cycles
Write (2+n) × Iφ + (1+m) × Bφ + 2 × Pφ
Read (2+n) × Iφ + (1+m) × Bφ + 2 × Pφ + (2+I) × Iφ
Note: These are the numbers of cycles when the instruction is executed from internal ROM or
internal RAM.
When Iφ:Bφ is 1:1; n = 0, I = 0
When Iφ:Bφ is 2:1; n = 0 or 1, I = 1
When Iφ:Bφ is 4:1; n = 0 to 3, I = 2
When Iφ:Bφ is 8:1; n = 0 to 7, I = 2
When Bφ:Pφ is 1:1; m = 0
When Bφ:Pφ is 2:1; m = 0 or 1
When Bφ:Pφ is 4:1; m = 0 to 3
Note that n and m depend on the internal execution state.
This product adopts synchronized logic and has a hierarchical bus structure. Data input and output
for each of the busses is synchronized with the rising edge of the Iφ clock for the C bus, the Bφ
clock for the I bus, and the Pφ clock for the peripheral bus.
Figure 8.41 shows an example of the write timing to the peripheral bus when the relationship
between the clocks is Iφ:Bφ:Pφ = 4:4:1. Data is output in synchronization with Iφ to the C bus, to
which the CPU is connected. When Iφ:Bφ is 1:1, 2 × Iφ + Bφ periods are required for data
transfers from the C bus to the I bus. For transfers from the I bus to the peripheral bus when Bφ:Pφ
is 4:1, since there are four clock cycles during a single Pφ clock period, the timing with which the
data is placed on the peripheral bus is as follows: there are four timings for Pφ × 1, and up to 4 Bφ
periods are required for the Pφ rising edge, which is the timing for transfers from the I bus to the

REJ09B0344-0300
peripheral bus (the example in figure 8.41 is for 4 × Bφ). Therefore, when Bφ:Pφ is 4:1, data is
transferred from the I bus to the peripheral bus in time (1+m) × Bφ, where m = 0 to 3 periods.
Note that the relationship between the timing with which the data appears on the I bus and the Pφ
rising edge depends on the program execution state. In figure 8.41, since n = 0 and m = 3, the
access time will be 2 × Iφ + 4 × Bφ + 2 × Pφ.

Figure 8.42 shows an example of the write timing to the peripheral bus when the relationship
between the clocks is Iφ:Bφ:Pφ = 4:2:1. Although transfers from the C bus to the peripheral bus
are performed the same way for write, for read, the value read from the peripheral bus must be
transferred to the CPU. Although the transfers from the peripheral bus to the I bus and from the I
bus to the C bus are all performed on the corresponding bus clock rising edge, since Iφ ≥ Bφ ≥ Pφ,
(2 + 1) × Iφ periods are actually required. In the example in figure 8.42, since n = 1, m = 1, and i =
1, the access period will be 3 × Iφ + 2 × Bφ + 2 × Pφ + 3 × Iφ.

8.6 Usage Notes
8.6.1 Burst ROM Interface
When the burst ROM interface (clock asynchronous) is used and the following three conditions
are met, read/write access from the external bus space immediately after write access may be
invalid.
1. The 16-bit bus width is used for the burst ROM interface (clock asynchronous). (The
CSnBCR.TYPE[2:0] setting is B'001 and the CSnWCR.BSZ[1:0] setting is B'10)
2. The burst length is specified as 4. (The CSnWCR.BST[1:0] setting is B'10)
3. Write-back is performed with operand cache or 16-byte write access is performed with the
DMAC for the burst ROM interface set as above.

Section 9 Direct Memory Access Controller (DMAC)
The DMAC can be used in place of the CPU to perform high-speed transfers between external
devices that have DACK (transfer request acknowledge signal), external memory, on-chip
memory, memory-mapped external devices, and on-chip peripheral modules.
9.1 Features
• Number of channels: Eight channels (channels 0 to 7) selectable
Four channels (channels 0 to 3) can receive external requests.
• 4-Gbyte physical address space
• Transfer data length is selectable: Byte, word (two bytes), longword (four bytes), and 16 bytes
(longword × 4)
• Maximum transfer count: 16,777,216 transfers (24 bits)
• Address mode: Dual address mode and single address mode are supported.
• Transfer requests
⎯ External request
⎯ On-chip peripheral module request
⎯ Auto request
The following modules can issue on-chip peripheral module requests.
⎯ Eight SCIF sources, two IIC3 sources, one A/D converter source, five MTU2 sources, and
two CMT sources
• Selectable bus modes
⎯ Cycle steal mode (normal mode and intermittent mode)
⎯ Burst mode
• Selectable channel priority levels: The channel priority levels are selectable between fixed
mode and round-robin mode.
• Interrupt request: An interrupt request can be sent to the CPU on completion of half- or full-
data transfer. Through the HE and HIE bits in CHCR, an interrupt is specified to be issued to
the CPU when half of the initially specified DMA transfer is completed.
• External request detection: There are following four types of DREQ input detection.
⎯ Low level detection
⎯ High level detection
⎯ Rising edge detection
⎯ Falling edge detection
Section 9 Direct Memory Access Controller (DMAC)
Rev. 3.00 Mar. 04, 2009 Page 300 of 1168
REJ09B0344-0300
• Transfer request acknowledge and transfer end signals: Active levels for DACK and TEND
can be set independently.
• Support of reload functions in DMA transfer information registers: DMA transfer using the
same information as the current transfer can be repeated automatically without specifying the
information again. Modifying the reload registers during DMA transfer enables next DMA
transfer to be done using different transfer information. The reload function can be enabled or
disabled independently in each channel.

9.3.1 DMA Source Address Registers (SAR)
The DMA source address registers (SAR) are 32-bit readable/writable registers that specify the
source address of a DMA transfer. During a DMA transfer, these registers indicate the next source
address. When the data of an external device with DACK is transferred in single address mode,
SAR is ignored.
To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address
boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary.
SAR is initialized to H'00000000 by a reset and retains the value in software standby mode and
module standby mode.

9.3.2 DMA Destination Address Registers (DAR)
The DMA destination address registers (DAR) are 32-bit readable/writable registers that specify
the destination address of a DMA transfer. During a DMA transfer, these registers indicate the
next destination address. When the data of an external device with DACK is transferred in single
address mode, DAR is ignored.
To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address

9.3.3 DMA Transfer Count Registers (DMATCR)
The DMA transfer count registers (DMATCR) are 32-bit readable/writable registers that specify
the number of DMA transfers. The transfer count is 1 when the setting is H'00000001, 16,777,215
when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. During a DMA
transfer, these registers indicate the remaining transfer count.
The upper eight bits of DMATCR are always read as 0, and the write value should always be 0. To
transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one.
DMATCR is initialized to H'00000000 by a reset and retains the value in software standby mode
and module standby mode.

9.3.4 DMA Channel Control Registers (CHCR)
The DMA channel control registers (CHCR) are 32-bit readable/writable registers that control
DMA transfer mode.
The DO, AM, AL, DL, and DS bits which specify the DREQ and DACK external pin functions
can be read and written to in channels 0 to 3, but they are reserved in channels 4 to 7. The TL bit
which specifies the TEND external pin function can be read and written to in channels 0 and 1, but
it is reserved in channels 2 to 7.
CHCR is initialized to H'00000000 by a reset and retains the value in software standby mode and
module standby mode.

9.3.5 DMA Reload Source Address Registers (RSAR)
The DMA reload source address registers (RSAR) are 32-bit readable/writable registers.
When the reload function is enabled, the RSAR value is written to the source address register
(SAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer
can be preset in RSAR during the current DMA transfer. When the reload function is disabled,
RSAR is ignored.
To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address
boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary.
RSAR is initialized to H'00000000 by a reset and retains the value in software standby mode and
module standby mode.

9.3.6 DMA Reload Destination Address Registers (RDAR)
The DMA reload destination address registers (RDAR) are 32-bit readable/writable registers.
When the reload function is enabled, the RDAR value is written to the destination address register
(DAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer
can be preset in RDAR during the current DMA transfer. When the reload function is disabled,
RDAR is ignored.
To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address
boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary.
RDAR is initialized to H'00000000 by a reset and retains the value in software standby mode and

9.3.7 DMA Reload Transfer Count Registers (RDMATCR)
The DMA reload transfer count registers (RDMATCR) are 32-bit readable/writable registers.
When the reload function is enabled, the RDMATCR value is written to the transfer count register
(DMATCR) at the end of the current DMA transfer. In this case, a new value for the next DMA
transfer can be preset in RDMATCR during the current DMA transfer. When the reload function
is disabled, RDMATCR is ignored.
The upper eight bits of RDMATCR are always read as 0, and the write value should always be 0.
As in DMATCR, the transfer count is 1 when the setting is H'00000001, 16,777,215 when
H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. To transfer data in
16 bytes, one 16-byte transfer (128 bits) counts one.
RDMATCR is initialized to H'00000000 by a reset and retains the value in software standby mode
and module standby mode.

0 DME 0 R/W DMA Master Enable
Enables or disables DMA transfer on all channels. If
the DME bit and DE bit in CHCR are set to 1, DMA
transfer is enabled.
However, transfer is enabled only when the TE bit in
CHCR of the transfer corresponding channel, the NMIF
bit in DMAOR, and the AE bit are all cleared to 0.
Clearing the DME bit to 0 can terminate the DMA
transfer on all channels.
0: DMA transfer is disabled on all channels
1: DMA transfer is enabled on all channels
Note: * To clear flags, read the register and then write 0 only to the bits that were read as 1.
Write 1 to the bits that were read as 0.
If the priority mode bits are modified after a DMA transfer, the channel priority is initialized. If
fixed mode 2 is specified, the channel priority is specified as CH0 > CH4 > CH1 > CH5 > CH2 >
CH6 > CH3 > CH7. If fixed mode 1 is specified, the channel priority is specified as CH0 > CH1 >
CH2 > CH3 > CH4 > CH5 > CH6 > CH7. If round-robin mode is specified, the transfer end
channel is reset.
Table 9.3 show the priority change in each mode (modes 0 to 2) specified by the priority mode
bits. In each priority mode, the channel priority to accept the next transfer request may change in
up to three ways according to the transfer end channel.
Section 9 Direct Memory Access Controller (DMAC)
Rev. 3.00 Mar. 04, 2009 Page 324 of 1168

For example, when the transfer end channel is channel 1, the priority of the channel to accept the
next transfer request is specified as CH2 > CH3 > CH0 >CH1 > CH4 > CH5 > CH6 > CH7. When
the transfer end channel is any one of the channels 4 to 7, round-robin will not be applied and the
priority level is not changed at the end of transfer in the channels 4 to 7.
The DMAC internal operation for an address error is as follows:
• No address error: Read (source to DMAC) → Write (DMAC to destination)
• Address error in source address: Nop → Nop
• Address error in destination address: Read → Nop

When MID or RID other than the values listed in table 9.4 is set, the operation of this LSI is not
guaranteed. The transfer request from DMARS is valid only when the resource select bits
(RS[3:0]) in CHCR0 to CHCR7 have been set to B'1000. Otherwise, even if DMARS has been set,
the transfer request source is not accepted.

9.4 Operation
When there is a DMA transfer request, the DMAC starts the transfer according to the
predetermined channel priority order; when the transfer end conditions are satisfied, it ends the
transfer. Transfers can be requested in three modes: auto request, external request, and on-chip
peripheral module request. In bus mode, burst mode or cycle steal mode can be selected.
9.4.1 Transfer Flow
After the DMA source address registers (SAR), DMA destination address registers (DAR), DMA
transfer count registers (DMATCR), DMA channel control registers (CHCR), DMA operation
register (DMAOR), and DMA extension resource selector (DMARS) are set for the target transfer
conditions, the DMAC transfers data according to the following procedure:
1. Checks to see if transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0)
2. When a transfer request comes and transfer is enabled, the DMAC transfers one transfer unit of
data (depending on the TS0 and TS1 settings). For an auto request, the transfer begins
automatically when the DE bit and DME bit are set to 1. The DMATCR value will be
decremented by 1 for each transfer. The actual transfer flows vary by address mode and bus
mode.
3. When half of the specified transfer count is exceeded (when DMATCR reaches half of the
initial value), an HEI interrupt is sent to the CPU if the HIE bit in CHCR is set to 1.
4. When transfer has been completed for the specified count (when DMATCR reaches 0), the
transfer ends normally. If the IE bit in CHCR is set to 1 at this time, a DEI interrupt is sent to
the CPU.
5. When an address error in the DMAC or an NMI interrupt is generated, the transfer is
terminated. Transfers are also terminated when the DE bit in CHCR or the DME bit in
DMAOR is cleared to 0.
Figure 9.2 is a flowchart of this procedure.

9.4.2 DMA Transfer Requests
DMA transfer requests are basically generated in either the data transfer source or destination, but
they can also be generated in external devices and on-chip peripheral modules that are neither the
transfer source nor destination.
Transfers can be requested in three modes: auto request, external request, and on-chip peripheral
module request. The request mode is selected by the RS[3:0] bits in CHCR_0 to CHCR_7 and
DMARS0 to DMARS3.
(1) Auto-Request Mode
When there is no transfer request signal from an external source, as in a memory-to-memory
transfer or a transfer between memory and an on-chip peripheral module unable to request a
transfer, auto-request mode allows the DMAC to automatically generate a transfer request signal
internally. When the DE bits in CHCR_0 to CHCR_7 and the DME bit in DMAOR are set to 1,
the transfer begins so long as the TE bits in CHCR_0 to CHCR_7, and the AE and NMIF bits in
DMAOR are 0.
(2) External Request Mode
In this mode a transfer is performed at the request signals (DREQ0 to DREQ3) of an external
device. Choose one of the modes shown in table 9.5 according to the application system. When the
DMA transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0), DMA transfer is
performed upon a request at the DREQ input.

Choose to detect DREQ by either the edge or level of the signal input with the DL and DS bits in
CHCR_0 to CHCR_3 as shown in table 9.6. The source of the transfer request does not have to be
the data transfer source or destination.

1 Rising edge detection
When DREQ is accepted, the DREQ pin enters the request accept disabled state (non-sensitive
period). After issuing acknowledge DACK signal for the accepted DREQ, the DREQ pin again
enters the request accept enabled state.
When DREQ is used by level detection, there are following two cases by the timing to detect the
next DREQ after outputting DACK.
Overrun 0: Transfer is terminated after the same number of transfer has been performed as
requests.
Overrun 1: Transfer is terminated after transfers have been performed for (the number of requests
plus 1) times.
The DO bit in CHCR selects this overrun 0 or overrun 1.

REJ09B0344-0300
(3) On-Chip Peripheral Module Request
In this mode, the transfer is performed in response to the DMA transfer request signal from an on-
chip peripheral module.
DMA transfer request signals from on-chip peripheral modules to the DMAC include transmit
data empty and receive data full requests from the SCIF, A/D conversion end request from the
A/D converter, compare match request from the CMT, and data transfer requests from the IIC3
and MTU2.
When a transfer request signal is sent in on-chip peripheral module request mode while DMA
transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, and NMIF = 0), DMA transfer is
performed.
When the transmit data empty from the SCIF is selected, specify the transfer destination as the
corresponding SCIF transmit data register. Likewise, when the receive data full from the SCIF is
selected, specify the transfer source as the corresponding SCIF receive data register. When a
transfer request is made by the A/D converter, the transfer source must be the A/D data register
(ADDR). When the IIC3 transmit is selected as the transfer request, the transfer destination must
be ICDRT; when the IIC3 reception is selected as the transfer request, the transfer source must be
ICDRR. Any address can be specified for data transfer source and destination when a transfer
request is sent from the CMT or MTU2.

9.4.3 Channel Priority
When the DMAC receives simultaneous transfer requests on two or more channels, it selects a
channel according to a predetermined priority order. Three modes (fixed mode 1, fixed mode 2,
and round-robin mode) are selected using the PR1 and PR0 bits in DMAOR.
(1) Fixed Mode
In fixed modes, the priority levels among the channels remain fixed. There are two kinds of fixed
modes as follows:
Fixed mode 1: CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7
Fixed mode 2: CH0 > CH4 > CH1 > CH5 > CH2 > CH6 > CH3 > CH7
These are selected by the PR1 and PR0 bits in the DMA operation register (DMAOR).
(2) Round-Robin Mode
Each time one unit of word, byte, longword, or 16 bytes is transferred on one channel, the priority
order is rotated. The channel on which the transfer was just finished is rotated to the lowest of the
priority order among the four round-robin channels (channels 0 to 4). The priority of the channels
other than the round-robin channels (channels 0 to 4) does not change even in round-robin mode.
The round-robin mode operation is shown in figure 9.3. The priority in round-robin mode is CH0
> CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 immediately after a reset.
When round-robin mode has been specified, do not concurrently specify cycle steal mode and
burst mode as the bus modes of any two or more channels.
Section 9 Direct Memory Access Controller (DMAC)
Rev. 3.00 Mar. 04, 2009 Page 334 of 1168
REJ09B0344-0300
Channel 2 is given the lowest priority
among the round-robin channels. The
priority of channels 0 and 1, which were
higher than channel 2, is also shifted. If
there is a transfer request only to
channel 5 immediately after that, the
priority does not change because
channel 5 is not a round-robin channel.
Channel 1 is given the lowest priority
among the round-robin channels. The
priority of channel 0, which was higher
than channel 1, is also shifted.
Channel 0 is given the lowest priority
among the round-robin channels.

Figure 9.4 shows how the priority order changes when channel 0 and channel 3 transfers are
requested simultaneously and a channel 1 transfer is requested during the channel 0 transfer. The
DMAC operates as follows:
1. Transfer requests are generated simultaneously to channels 0 and 3.
2. Channel 0 has a higher priority, so the channel 0 transfer begins first (channel 3 waits for
transfer).
3. A channel 1 transfer request occurs during the channel 0 transfer (channels 1 and 3 are both
waiting)
4. When the channel 0 transfer ends, channel 0 is given the lowest priority among the round-robin
channels.
5. At this point, channel 1 has a higher priority than channel 3, so the channel 1 transfer begins
(channel 3 waits for transfer).
6. When the channel 1 transfer ends, channel 1 is given the lowest priority among the round-robin
channels.
7. The channel 3 transfer begins.
8. When the channel 3 transfer ends, channels 3 and 2 are lowered in priority so that channel 3 is
given the lowest priority among the round-robin channels.

9.4.4 DMA Transfer Types
DMA transfer has two types; single address mode transfer and dual address mode transfer. They
depend on the number of bus cycles of access to the transfer source and destination. A data
transfer timing depends on the bus mode, which is cycle steal mode or burst mode. The DMAC
supports the transfers shown in table 9.9.

(1) Address Modes
(a) Dual Address Mode
In dual address mode, both the transfer source and destination are accessed (selected) by an
address. The transfer source and destination can be located externally or internally.
DMA transfer requires two bus cycles because data is read from the transfer source in a data read
cycle and written to the transfer destination in a data write cycle. At this time, transfer data is
temporarily stored in the DMAC. In the transfer between external memories as shown in figure
9.5, data is read to the DMAC from one external memory in a data read cycle, and then that data is
written to the other external memory in a data write cycle.

Auto request, external request, and on-chip peripheral module request are available for the transfer

cycle.

(b) Single Address Mode
In single address mode, both the transfer source and destination are external devices, either of
them is accessed (selected) by the DACK signal, and the other device is accessed by an address. In
this mode, the DMAC performs one DMA transfer in one bus cycle, accessing one of the external
devices by outputting the DACK transfer request acknowledge signal to it, and at the same time
outputting an address to the other device involved in the transfer. For example, in the case of
transfer between external memory and an external device with DACK shown in figure 9.7, when
the external device outputs data to the data bus, that data is written to the external memory in the
same bus cycle.

Two kinds of transfer are possible in single address mode: (1) transfer between an external device

with DACK and external memory. In both cases, only the external request signal (DREQ) is used
for transfer requests.

(2) Bus Modes
There are two bus modes; cycle steal and burst. Select the mode by the TB bits in the channel
control registers (CHCR).
(a) Cycle Steal Mode
• Normal mode
In normal mode of cycle steal, the bus mastership is given to another bus master after a one-
transfer-unit (byte, word, longword, or 16-byte unit) DMA transfer. When another transfer
request occurs, the bus mastership is obtained from another bus master and a transfer is
performed for one transfer unit. When that transfer ends, the bus mastership is passed to
another bus master. This is repeated until the transfer end conditions are satisfied.
The cycle-steal normal mode can be used for any transfer section; transfer request source,
transfer source, and transfer destination.
Figure 9.9 shows an example of DMA transfer timing in cycle-steal normal mode. Transfer
conditions shown in the figure are;
⎯ Dual address mode
⎯ DREQ low level detection

• Intermittent Mode 16 and Intermittent Mode 64
In intermittent mode of cycle steal, DMAC returns the bus mastership to other bus master
whenever a unit of transfer (byte, word, longword, or 16 bytes) is completed. If the next
transfer request occurs after that, DMAC obtains the bus mastership from other bus master
after waiting for 16 or 64 cycles of Bφ clock. DMAC then transfers data of one unit and returns
the bus mastership to other bus master. These operations are repeated until the transfer end
condition is satisfied. It is thus possible to make lower the ratio of bus occupation by DMA
transfer than normal mode of cycle steal.
The cycle-steal intermittent mode can be used for any transfer section; transfer request source,
transfer source, and transfer destination. The bus modes, however, must be cycle steal mode in
all channels.
Figure 9.10 shows an example of DMA transfer timing in cycle-steal intermittent mode.

(b) Burst Mode
In burst mode, once the DMAC obtains the bus mastership, it does not release the bus mastership
and continues to perform transfer until the transfer end condition is satisfied. In external request
mode with low level detection of the DREQ pin, however, when the DREQ pin is driven high, the
bus mastership is passed to another bus master after the DMAC transfer request that has already
been accepted ends, even if the transfer end conditions have not been satisfied.

Notes: 1. External requests, auto requests, and on-chip peripheral module requests are all
available. However, along with the exception of CMT and MTU2 as the transfer request
source, the requesting module must be designated as the transfer source or the
transfer destination.
2. Access size permitted for the on-chip peripheral module register functioning as the
transfer source or transfer destination.
3. If the transfer request is an external request, channels 0 to 3 are only available.
4. External requests, auto requests, and on-chip peripheral module requests are all
available. In the case of on-chip peripheral module requests, however, the CMT and
MTU2 are only available.
5. Only cycle steal except for the MTU2 and CMT as the transfer request source.

(4) Bus Mode and Channel Priority
In priority fixed mode (CH0 > CH1), when channel 1 is transferring data in burst mode and a
request arrives for transfer on channel 0, which has higher-priority, the data transfer on channel 0
will begin immediately. In this case, if the transfer on channel 0 is also in burst mode, the transfer
on channel 1 will only resume on completion of the transfer on channel 0.
When channel 0 is in cycle steal mode, one transfer-unit of data on this channel, which has the
higher priority, is transferred. Data is then transferred continuously to channel 1 without releasing
the bus. The bus mastership will then switch between the two in this order: channel 0, channel 1,
channel 0, channel 1, etc. That is, the CPU cycle after the data transfer in cycle steal mode is
replaced with a burst-mode transfer cycle (priority execution of burst-mode cycle). An example of
this is shown in figure 9.12.
When multiple channels are in burst mode, data transfer on the channel that has the highest
priority is given precedence. When DMA transfer is being performed on multiple channels, the
bus mastership is not released to another bus-master device until all of the competing burst-mode
transfers have been completed.

9.4.5 Number of Bus Cycles and DREQ Pin Sampling Timing
(1) Number of Bus Cycles
When the DMAC is the bus master, the number of bus cycles is controlled by the bus state
controller (BSC) in the same way as when the CPU is the bus master. For details, see section 8,
Bus State Controller (BSC).
(2) DREQ Pin Sampling Timing
Figures 9.13 to 9.16 show the DREQ input sampling timings in each bus mode.

Figure 9.17 Example of DMA Transfer End Signal Timing
(Cycle Steal Mode Level Detection)
The unit of the DMA transfer is divided into multiple bus cycles when 16-byte transfer is
performed for an 8-bit or 16-bit external device, when longword access is performed for an 8-bit
or 16-bit external device, or when word access is performed for an 8-bit external device. When a
setting is made so that the DMA transfer size is divided into multiple bus cycles and the CS signal
is negated between bus cycles, note that DACK and TEND are divided like the CS signal for data
alignment. Also, if the DREQ detection is set to level-detection mode (DS bit in CHCR = 0), the
DREQ sampling may not be detected correctly with divided DACK, and one extra overrun may
occur at maximum.
Use a setting that does not divide DACK or specify a transfer size smaller than the external device
bus width if DACK is divided. Figure 9.18 shows this example.

9.5 Usage Note
9.5.1 Half-End Flag Setting and Half-End Interrupt
When monitoring the half-end flag status in CHCR or using the half-end interrupt together with
the reload function, the following precautions must be observed.
For the reload transfer count in RDMATCR, always set a value equal to the initial transfer count
(the value in DMATCR).
If the first setting of DMATCR differs from the RDMATCR setting used in the second and
following DMA transfer, the half-end flag setting timing may be earlier than half of the transfer
count or the half-end flag may not be set. The same is true for the half-end interrupt.

10.3.1 Timer Control Register (TCR)
The TCR registers are 8-bit readable/writable registers that control the TCNT operation for each
channel. The MTU2 has a total of eight TCR registers, one each for channels 0 to 4 and three
(TCRU_5, TCRV_5, and TCRW_5) for channel 5. TCR register settings should be conducted
only when TCNT operation is stopped.

See tables 10.4 and 10.5 for details.
4, 3 CKEG[1:0] 00 R/W Clock Edge 0 and 1
These bits select the input clock edge. When the input
clock is counted using both edges, the input clock
period is halved (e.g. Pφ/4 both edges = Pφ/2 rising
edge). If phase counting mode is used on channels 1
and 2, this setting is ignored and the phase counting
mode setting has priority. Internal clock edge selection
is valid when the input clock is Pφ/4 or slower. When
Pφ/1 or the overflow/underflow of another channel is
selected for the input clock, although values can be
written, counter operation compiles with the initial value.
00: Count at rising edge
01: Count at falling edge
1x: Count at both edges
2 to 0 TPSC[2:0] 000 R/W Time Prescaler 0 to 2
These bits select the TCNT counter clock. The clock
source can be selected independently for each channel.

5 BFB 0 R/W Buffer Operation B
Specifies whether TGRB is to operate in the normal
way, or TGRB and TGRD are to be used together for
buffer operation. When TGRD is used as a buffer
register, TGRD input capture/output compare is not
generated in a mode other than complementary PWM.
TGRD compare match is generated in complementary
PWM mode. When compare match occurs during the
Tb period in complementary PWM mode, TGFD is set.
Therefore, set the TGIED bit in the timer interrupt
enable register 3/4 (TIER_3/4) to 0.
In channels 1 and 2, which have no TGRD, bit 5 is
reserved. It is always read as 0 and cannot be modified.
0: TGRB and TGRD operate normally
1: TGRB and TGRD used together for buffer operation
4 BFA 0 R/W Buffer Operation A
Specifies whether TGRA is to operate in the normal
way, or TGRA and TGRC are to be used together for
buffer operation. When TGRC is used as a buffer
register, TGRC input capture/output compare is not
generated in a mode other than complementary PWM.
TGRC compare match is generated when in
complementary PWM mode. When compare match for
channel 4 occurs during the Tb period in
complementary PWM mode, TGFC is set. Therefore,
set the TGIEC bit in the timer interrupt enable register 4
(TIER_4) to 0.
In channels 1 and 2, which have no TGRC, bit 4 is
reserved. It is always read as 0 and cannot be modified.
0: TGRA and TGRC operate normally
1: TGRA and TGRC used together for buffer operation

Notes: 1. PWM mode 2 cannot be set for channels 3 and 4.
2. Phase counting mode cannot be set for channels 0, 3, and 4.
3. Reset synchronous PWM mode, complementary PWM mode can only be set for
channel 3. When channel 3 is set to reset synchronous PWM mode or complementary
PWM mode, the channel 4 settings become ineffective and automatically conform to the
channel 3 settings. However, do not set channel 4 to reset synchronous PWM mode or
complementary PWM mode. Reset synchronous PWM mode and complementary PWM
mode cannot be set for channels 0, 1, and 2.

10.3.3 Timer I/O Control Register (TIOR)
The TIOR registers are 8-bit readable/writable registers that control the TGR registers. The MTU2
has a total of eleven TIOR registers, two each for channels 0, 3, and 4, one each for channels 1 and
2, and three (TIORU_5, TIORV_5, and TIORW_5) for channel 5.
TIOR should be set while TMDR is set in normal operation, PWM mode, or phase counting mode.
The initial output specified by TIOR is valid when the counter is stopped (the CST bit in TSTR is
cleared to 0). Note also that, in PWM mode 2, the output at the point at which the counter is
cleared to 0 is specified.
When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register
operates as a buffer register.

10.3.14 Timer General Register (TGR)
The TGR registers are 16-bit readable/writable registers. The MTU2 has 21 TGR registers, six for
channel 0, two each for channels 1 and 2, four each for channels 3 and 4, and three for channel 5.
TGRA, TGRB, TGRC, and TGRD function as either output compare or input capture registers.
TGRC and TGRD for channels 0, 3, and 4 can also be designated for operation as buffer registers.
TGR buffer register combinations are TGRA and TGRC, and TGRB and TGRD.
TGRE_0 and TGRF_0 function as compare registers. When the TCNT_0 count matches the
TGRE_0 value, an A/D converter start request can be issued. TGRF can also be designated for
operation as a buffer register. TGR buffer register combination is TGRE and TGRF.
TGRU_5, TGRV_5, and TGRW_5 function as compare match, input capture, or external pulse
width measurement registers.

timer A/D converter start request control register (TADCR), timer A/D converter start request
cycle set registers (TADCOR), and timer A/D converter start request cycle set buffer registers
(TADCOBR) are 16-bit registers. A 16-bit data bus to the bus master enables 16-bit read/writes. 8-
bit read/write is not possible. Always access in 16-bit units.
All registers other than the above registers are 8-bit registers. These are connected to the CPU by a
16-bit data bus, so 16-bit read/writes and 8-bit read/writes are both possible.

10.4 Operation
10.4.1 Basic Functions
Each channel has a TCNT and TGR register. TCNT performs up-counting, and is also capable of
free-running operation, cycle counting, and external event counting.
Each TGR can be used as an input capture register or output compare register.
Always select MTU2 external pins set function using the pin function controller (PFC).
(1) Counter Operation
When one of bits CST0 to CST4 in TSTR or bits CSTU5, CSTV5, and CSTW5 in TSTR_5 is set
to 1, the TCNT counter for the corresponding channel begins counting. TCNT can operate as a
free-running counter, periodic counter, for example.

(b) Free-Running Count Operation and Periodic Count Operation:
Immediately after a reset, the MTU2’s TCNT counters are all designated as free-running counters.
When the relevant bit in TSTR is set to 1 the corresponding TCNT counter starts up-count
operation as a free-running counter. When TCNT overflows (from H'FFFF to H'0000), the TCFV
bit in TSR is set to 1. If the value of the corresponding TCIEV bit in TIER is 1 at this point, the
MTU2 requests an interrupt. After overflow, TCNT starts counting up again from H'0000.
Figure 10.5 illustrates free-running counter operation.

Figure 10.5 Free-Running Counter Operation
When compare match is selected as the TCNT clearing source, the TCNT counter for the relevant
channel performs periodic count operation. The TGR register for setting the period is designated
as an output compare register, and counter clearing by compare match is selected by means of bits
CCLR0 to CCLR2 in TCR. After the settings have been made, TCNT starts up-count operation as
a periodic counter when the corresponding bit in TSTR is set to 1. When the count value matches
the value in TGR, the TGF bit in TSR is set to 1 and TCNT is cleared to H'0000.
If the value of the corresponding TGIE bit in TIER is 1 at this point, the MTU2 requests an
interrupt. After a compare match, TCNT starts counting up again from H'0000.

(3) Input Capture Function
The TCNT value can be transferred to TGR on detection of the TIOC pin input edge.
Rising edge, falling edge, or both edges can be selected as the detected edge. For channels 0 and 1,
it is also possible to specify another channel's counter input clock or compare match signal as the
input capture source.
Note: When another channel's counter input clock is used as the input capture input for channels
0 and 1, Pφ/1 should not be selected as the counter input clock used for input capture
input. Input capture will not be generated if Pφ/1 is selected.

10.4.2 Synchronous Operation
In synchronous operation, the values in a number of TCNT counters can be rewritten
simultaneously (synchronous presetting). Also, a number of TCNT counters can be cleared
simultaneously by making the appropriate setting in TCR (synchronous clearing).
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 4 can all be designated for synchronous operation. Channel 5 cannot be used for
synchronous operation.

In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to

synchronous clearing has been set for the channel 1 and 2 counter clearing source.
Three-phase PWM waveforms are output from pins TIOC0A, TIOC1A, and TIOC2A. At this
time, synchronous presetting, and synchronous clearing by TGRB_0 compare match, are
performed for channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM
cycle.

10.4.3 Buffer Operation
Buffer operation, provided for channels 0, 3, and 4, enables TGRC and TGRD to be used as buffer
registers. In channel 0, TGRF can also be used as a buffer register.
Buffer operation differs depending on whether TGR has been designated as an input capture
register or as a compare match register.
Note: TGRE_0 cannot be designated as an input capture register and can only operate as a
compare match register.
Table 10.43 shows the register combinations used in buffer operation.

• When TGR is an output compare register
When a compare match occurs, the value in the buffer register for the corresponding channel is
transferred to the timer general register.
This operation is illustrated in figure 10.14.

Figure 10.17 shows an operation example in which PWM mode 1 has been designated for channel
0, and buffer operation has been designated for TGRA and TGRC. The settings used in this
example are TCNT clearing by compare match B, 1 output at compare match A, and 0 output at
compare match B. In this example, the TTSA bit in TBTM is cleared to 0.
As buffer operation has been set, when compare match A occurs the output changes and the value
in buffer register TGRC is simultaneously transferred to timer general register TGRA. This
operation is repeated each time that compare match A occurs.
For details of PWM modes, see section 10.4.5, PWM Modes.

(3) Selecting Timing for Transfer from Buffer Registers to Timer General Registers in
Buffer Operation
The timing for transfer from buffer registers to timer general registers can be selected in PWM
mode 1 or 2 for channel 0 or in PWM mode 1 for channels 3 and 4 by setting the buffer operation
transfer mode registers (TBTM_0, TBTM_3, and TBTM_4). Either compare match (initial
setting) or TCNT clearing can be selected for the transfer timing. TCNT clearing as transfer
timing is one of the following cases.
• When TCNT overflows (H'FFFF to H'0000)
• When H'0000 is written to TCNT during counting
• When TCNT is cleared to H'0000 under the condition specified in the CCLR2 to CCLR0 bits
in TCR
Note: TBTM must be modified only while TCNT stops.
Figure 10.19 shows an operation example in which PWM mode 1 is designated for channel 0 and
buffer operation is designated for TGRA_0 and TGRC_0. The settings used in this example are
TCNT_0 clearing by compare match B, 1 output at compare match A, and 0 output at compare
match B. The TTSA bit in TBTM_0 is set to 1.

10.4.4 Cascaded Operation
In cascaded operation, two 16-bit counters for different channels are used together as a 32-bit
counter.
This function works by counting the channel 1 counter clock upon overflow/underflow of
TCNT_2 as set in bits TPSC0 to TPSC2 in TCR.
Underflow occurs only when the lower 16-bit TCNT is in phase counting mode.
Table 10.44 shows the register combinations used in cascaded operation.
Note: When phase counting mode is set for channel 1, the counter clock setting is invalid and the
counters operates independently in phase counting mode.
Table 10.44 Cascaded Combinations
Combination Upper 16 Bits Lower 16 Bits
Channels 1 and 2 TCNT_1 TCNT_2
For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional
input capture input pins can be specified by the input capture control register (TICCR). For input
capture in cascade connection, refer to section 10.7.22, Simultaneous Capture of TCNT_1 and
TCNT_2 in Cascade Connection.

edge for the input capture timing while the IOA0 to IOA3 bits in TIOR_2 have selected the
TIOC2A rising edge for the input capture timing.
Under these conditions, the rising edge of both TIOC1A and TIOC2A is used for the TGRA_1
input capture condition. For the TGRA_2 input capture condition, the TIOC2A rising edge is used.

TIOR_2 have selected the TIOC2A rising edge for the input capture timing.
Under these conditions, as TIOR_1 has selected TGRA_0 compare match or input capture
occurrence for the input capture timing, the TIOC2A edge is not used for TGRA_1 input capture
condition although the I2AE bit in TICCR has been set to 1.

10.4.5 PWM Modes
In PWM mode, PWM waveforms are output from the output pins. The output level can be selected
as 0, 1, or toggle output in response to a compare match of each TGR.
TGR registers settings can be used to output a PWM waveform in the range of 0% to 100% duty.
Designating TGR compare match as the counter clearing source enables the period to be set in that
register. All channels can be designated for PWM mode independently. Synchronous operation is
also possible.
There are two PWM modes, as described below.
• PWM mode 1
PWM output is generated from the TIOCA and TIOCC pins by pairing TGRA with TGRB and
TGRC with TGRD. The output specified by bits IOA0 to IOA3 and IOC0 to IOC3 in TIOR is
output from the TIOCA and TIOCC pins at compare matches A and C, and the output
specified by bits IOB0 to IOB3 and IOD0 to IOD3 in TIOR is output at compare matches B
and D. The initial output value is the value set in TGRA or TGRC. If the set values of paired
TGRs are identical, the output value does not change when a compare match occurs.
In PWM mode 1, a maximum 8-phase PWM output is possible.
• PWM mode 2
PWM output is generated using one TGR as the cycle register and the others as duty registers.
The output specified in TIOR is performed by means of compare matches. Upon counter
clearing by a synchronization register compare match, the output value of each pin is the initial
value set in TIOR. If the set values of the cycle and duty registers are identical, the output
value does not change when a compare match occurs.
In PWM mode 2, a maximum 8-phase PWM output is possible in combination use with
synchronous operation.
The correspondence between PWM output pins and registers is shown in table 10.46.

10.4.6 Phase Counting Mode
In phase counting mode, the phase difference between two external clock inputs is detected and
TCNT is incremented/decremented accordingly. This mode can be set for channels 1 and 2.
When phase counting mode is set, an external clock is selected as the counter input clock and
TCNT operates as an up/down-counter regardless of the setting of bits TPSC0 to TPSC2 and bits
CKEG0 and CKEG1 in TCR. However, the functions of bits CCLR0 and CCLR1 in TCR, and of
TIOR, TIER, and TGR, are valid, and input capture/compare match and interrupt functions can be
used.
This can be used for two-phase encoder pulse input.
If overflow occurs when TCNT is counting up, the TCFV flag in TSR is set; if underflow occurs
when TCNT is counting down, the TCFU flag is set.
The TCFD bit in TSR is the count direction flag. Reading the TCFD flag reveals whether TCNT is
counting up or down.

(3) Phase Counting Mode Application Example
Figure 10.34 shows an example in which channel 1 is in phase counting mode, and channel 1 is
coupled with channel 0 to input servo motor 2-phase encoder pulses in order to detect position or
speed.
Channel 1 is set to phase counting mode 1, and the encoder pulse A-phase and B-phase are input
to TCLKA and TCLKB.
Channel 0 operates with TCNT counter clearing by TGRC_0 compare match; TGRA_0 and
TGRC_0 are used for the compare match function and are set with the speed control period and
position control period. TGRB_0 is used for input capture, with TGRB_0 and TGRD_0 operating
in buffer mode. The channel 1 counter input clock is designated as the TGRB_0 input capture
source, and the pulse widths of 2-phase encoder 4-multiplication pulses are detected.
TGRA_1 and TGRB_1 for channel 1 are designated for input capture, and channel 0 TGRA_0 and
TGRC_0 compare matches are selected as the input capture source and store the up/down-counter
values for the control periods.
This procedure enables the accurate detection of position and speed.

10.4.7 Reset-Synchronized PWM Mode
In reset-synchronized PWM mode, three-phase output of positive and negative PWM waveforms
that share a common wave transition point can be obtained by combining channels 3 and 4.
When set for reset-synchronized PWM mode, the TIOC3B, TIOC3D, TIOC4A, TIOC4C,
TIOC4B, and TIOC4D pins function as PWM output pins and TCNT3 functions as an upcounter.
Table 10.52 shows the PWM output pins used. Table 10.53 shows the settings of the registers.

10.4.8 Complementary PWM Mode
In complementary PWM mode, three-phase output of non-overlapping positive and negative
PWM waveforms can be obtained by combining channels 3 and 4. PWM waveforms without non-
overlapping interval are also available.
In complementary PWM mode, TIOC3B, TIOC3D, TIOC4A, TIOC4B, TIOC4C, and TIOC4D
pins function as PWM output pins, the TIOC3A pin can be set for toggle output synchronized with
the PWM period. TCNT_3 and TCNT_4 function as up/down counters.
Table 10.54 shows the PWM output pins used. Table 10.55 shows the settings of the registers
used.
A function to directly cut off the PWM output by using an external signal is supported as a port
function.

(2) Outline of Complementary PWM Mode Operation
In complementary PWM mode, 6-phase PWM output is possible. Figure 10.39 illustrates counter
operation in complementary PWM mode, and figure 10.40 shows an example of complementary
PWM mode operation.
(a) Counter Operation
In complementary PWM mode, three counters—TCNT_3, TCNT_4, and TCNTS—perform
up/down-count operations.
TCNT_3 is automatically initialized to the value set in TDDR when complementary PWM mode
is selected and the CST bit in TSTR is 0.
When the CST bit is set to 1, TCNT_3 counts up to the value set in TGRA_3, then switches to
down-counting when it matches TGRA_3. When the TCNT3 value matches TDDR, the counter
switches to up-counting, and the operation is repeated in this way.
TCNT_4 is initialized to H'0000.
When the CST bit is set to 1, TCNT4 counts up in synchronization with TCNT_3, and switches to
down-counting when it matches TCDR. On reaching H'0000, TCNT4 switches to up-counting,
and the operation is repeated in this way.
TCNTS is a read-only counter. It need not be initialized.
When TCNT_3 matches TCDR during TCNT_3 and TCNT_4 up/down-counting, down-counting
is started, and when TCNTS matches TCDR, the operation switches to up-counting. When
TCNTS matches TGRA_3, it is cleared to H'0000.
When TCNT_4 matches TDDR during TCNT_3 and TCNT_4 down-counting, up-counting is
started, and when TCNTS matches TDDR, the operation switches to down-counting. When
TCNTS reaches H'0000, it is set with the value in TGRA_3.
TCNTS is compared with the compare register and temporary register in which the PWM duty is
set during the count operation only.

Figure 10.39 Complementary PWM Mode Counter Operation
(b) Register Operation
In complementary PWM mode, nine registers are used, comprising compare registers, buffer
registers, and temporary registers. Figure 10.40 shows an example of complementary PWM mode
operation.
The registers which are constantly compared with the counters to perform PWM output are
TGRB_3, TGRA_4, and TGRB_4. When these registers match the counter, the value set in bits
OLSN and OLSP in the timer output control register (TOCR) is output.
The buffer registers for these compare registers are TGRD_3, TGRC_4, and TGRD_4.
Between a buffer register and compare register there is a temporary register. The temporary
registers cannot be accessed by the CPU.
Data in a compare register is changed by writing the new data to the corresponding buffer register.
The buffer registers can be read or written at any time.
The data written to a buffer register is constantly transferred to the temporary register in the Ta
interval. Data is not transferred to the temporary register in the Tb interval. Data written to a
buffer register in this interval is transferred to the temporary register at the end of the Tb interval.
The value transferred to a temporary register is transferred to the compare register when TCNTS
for which the Tb interval ends matches TGRA_3 when counting up, or H'0000 when counting
down. The timing for transfer from the temporary register to the compare register can be selected
with bits MD3 to MD0 in the timer mode register (TMDR). Figure 10.40 shows an example in
which the mode is selected in which the change is made in the trough.
In the tb interval (tb1 in figure 10.40) in which data transfer to the temporary register is not
performed, the temporary register has the same function as the compare register, and is compared

with the counter. In this interval, therefore, there are two compare match registers for one-phase
output, with the compare register containing the pre-change data, and the temporary register
containing the new data. In this interval, the three counters—TCNT_3, TCNT_4, and TCNTS—
and two registers—compare register and temporary register—are compared, and PWM output
controlled accordingly.

(c) Initialization
In complementary PWM mode, there are six registers that must be initialized. In addition, there is
a register that specifies whether to generate dead time (it should be used only when dead time
generation should be disabled).
Before setting complementary PWM mode with bits MD3 to MD0 in the timer mode register
(TMDR), the following initial register values must be set.
TGRC_3 operates as the buffer register for TGRA_3, and should be set with 1/2 the PWM carrier
cycle + dead time Td. The timer cycle buffer register (TCBR) operates as the buffer register for
the timer cycle data register (TCDR), and should be set with 1/2 the PWM carrier cycle. Set dead
time Td in the timer dead time data register (TDDR).
When dead time is not needed, the TDER bit in the timer dead time enable register (TDER) should
be cleared to 0, TGRC_3 and TGRA_3 should be set to 1/2 the PWM carrier cycle + 1, and TDDR
should be set to 1.
Set the respective initial PWM duty values in buffer registers TGRD_3, TGRC_4, and TGRD_4.
The values set in the five buffer registers excluding TDDR are transferred simultaneously to the
corresponding compare registers when complementary PWM mode is set.
Set TCNT_4 to H'0000 before setting complementary PWM mode.
Table 10.56 Registers and Counters Requiring Initialization
Register/Counter Set Value
TGRC_3 1/2 PWM carrier cycle + dead time Td
(1/2 PWM carrier cycle + 1 when dead time generation
is disabled by TDER)
TDDR Dead time Td (1 when dead time generation is
disabled by TDER)
TCBR 1/2 PWM carrier cycle
TGRD_3, TGRC_4, TGRD_4 Initial PWM duty value for each phase
TCNT_4 H'0000
Note: The TGRC_3 set value must be the sum of 1/2 the PWM carrier cycle set in TCBR and

must be set to 1/2 the PWM carrier cycle + 1.

(d) PWM Output Level Setting
In complementary PWM mode, the PWM pulse output level is set with bits OLSN and OLSP in
timer output control register 1 (TOCR1) or bits OLS1P to OLS3P and OLS1N to OLS3N in timer
output control register 2 (TOCR2).
The output level can be set for each of the three positive phases and three negative phases of 6-
phase output.
Complementary PWM mode should be cleared before setting or changing output levels.
(e) Dead Time Setting
In complementary PWM mode, PWM pulses are output with a non-overlapping relationship
between the positive and negative phases. This non-overlap time is called the dead time.
The non-overlap time is set in the timer dead time data register (TDDR). The value set in TDDR is
used as the TCNT_3 counter start value, and creates non-overlap between TCNT_3 and TCNT_4.
Complementary PWM mode should be cleared before changing the contents of TDDR.
(f) Dead Time Suppressing
Dead time generation is suppressed by clearing the TDER bit in the timer dead time enable
register (TDER) to 0. TDER can be cleared to 0 only when 0 is written to it after reading TDER =
1.
TGRA_3 and TGRC_3 should be set to 1/2 PWM carrier cycle + 1 and the timer dead time data
register (TDDR) should be set to 1.
By the above settings, PWM waveforms without dead time can be obtained. Figure 10.41 shows
an example of operation without dead time.

(g) PWM Cycle Setting
In complementary PWM mode, the PWM pulse cycle is set in two registers—TGRA_3, in which
the TCNT_3 upper limit value is set, and TCDR, in which the TCNT_4 upper limit value is set.
The settings should be made so as to achieve the following relationship between these two
registers:
With dead time: TGRA_3 set value = TCDR set value + TDDR set value
Without dead time: TGRA_3 set value = TCDR set value + 1
The TGRA_3 and TCDR settings are made by setting the values in buffer registers TGRC_3 and
TCBR. The values set in TGRC_3 and TCBR are transferred simultaneously to TGRA_3 and
TCDR in accordance with the transfer timing selected with bits MD3 to MD0 in the timer mode
register (TMDR).
The updated PWM cycle is reflected from the next cycle when the data update is performed at the
crest, and from the current cycle when performed in the trough. Figure 10.42 illustrates the
operation when the PWM cycle is updated at the crest.
See the following section, Register Data Updating, for the method of updating the data in each
buffer register.

(h) Register Data Updating
In complementary PWM mode, the buffer register is used to update the data in a compare register.
The update data can be written to the buffer register at any time. There are five PWM duty and
carrier cycle registers that have buffer registers and can be updated during operation.
There is a temporary register between each of these registers and its buffer register. When
subcounter TCNTS is not counting, if buffer register data is updated, the temporary register value
is also rewritten. Transfer is not performed from buffer registers to temporary registers when
TCNTS is counting; in this case, the value written to a buffer register is transferred after TCNTS
halts.
The temporary register value is transferred to the compare register at the data update timing set
with bits MD3 to MD0 in the timer mode register (TMDR). Figure 10.43 shows an example of
data updating in complementary PWM mode. This example shows the mode in which data
updating is performed at both the counter crest and trough.
When rewriting buffer register data, a write to TGRD_4 must be performed at the end of the
update. Data transfer from the buffer registers to the temporary registers is performed
simultaneously for all five registers after the write to TGRD_4.
A write to TGRD_4 must be performed after writing data to the registers to be updated, even when
not updating all five registers, or when updating the TGRD_4 data. In this case, the data written to
TGRD_4 should be the same as the data prior to the write operation.

(i) Initial Output in Complementary PWM Mode
In complementary PWM mode, the initial output is determined by the setting of bits OLSN and
OLSP in timer output control register 1 (TOCR1) or bits OLS1N to OLS3N and OLS1P to OLS3P
in timer output control register 2 (TOCR2).
This initial output is the PWM pulse non-active level, and is output from when complementary
PWM mode is set with the timer mode register (TMDR) until TCNT_4 exceeds the value set in
the dead time register (TDDR). Figure 10.44 shows an example of the initial output in
complementary PWM mode.
An example of the waveform when the initial PWM duty value is smaller than the TDDR value is
shown in figure 10.45.

(j) Complementary PWM Mode PWM Output Generation Method
In complementary PWM mode, 3-phase output is performed of PWM waveforms with a non-
overlap time between the positive and negative phases. This non-overlap time is called the dead
time.
A PWM waveform is generated by output of the output level selected in the timer output control
register in the event of a compare-match between a counter and data register. While TCNTS is
counting, data register and temporary register values are simultaneously compared to create
consecutive PWM pulses from 0 to 100%. The relative timing of on and off compare-match
occurrence may vary, but the compare-match that turns off each phase takes precedence to secure
the dead time and ensure that the positive phase and negative phase on times do not overlap.
Figures 10.46 to 10.48 show examples of waveform generation in complementary PWM mode.
The positive phase/negative phase off timing is generated by a compare-match with the solid-line
counter, and the on timing by a compare-match with the dotted-line counter operating with a delay
of the dead time behind the solid-line counter. In the T1 period, compare-match a that turns off the
negative phase has the highest priority, and compare-matches occurring prior to a are ignored. In
the T2 period, compare-match c that turns off the positive phase has the highest priority, and
compare-matches occurring prior to c are ignored.
In normal cases, compare-matches occur in the order a → b → c → d (or c → d → a' → b'), as
shown in figure 10.46.
If compare-matches deviate from the a → b → c → d order, since the time for which the negative
phase is off is less than twice the dead time, the figure shows the positive phase is not being turned
on. If compare-matches deviate from the c → d → a' → b' order, since the time for which the
positive phase is off is less than twice the dead time, the figure shows the negative phase is not
being turned on.
If compare-match c occurs first following compare-match a, as shown in figure 10.47, compare-
match b is ignored, and the negative phase is turned off by compare-match d. This is because
turning off of the positive phase has priority due to the occurrence of compare-match c (positive
phase off timing) before compare-match b (positive phase on timing) (consequently, the waveform
does not change since the positive phase goes from off to off).
Similarly, in the example in figure 10.48, compare-match a' with the new data in the temporary
register occurs before compare-match c, but other compare-matches occurring up to c, which turns
off the positive phase, are ignored. As a result, the negative phase is not turned on.
Thus, in complementary PWM mode, compare-matches at turn-off timings take precedence, and
turn-on timing compare-matches that occur before a turn-off timing compare-match are ignored.

(k) Complementary PWM Mode 0% and 100% Duty Output
In complementary PWM mode, 0% and 100% duty cycles can be output as required. Figures
10.49 to 10.53 show output examples.
100% duty output is performed when the data register value is set to H'0000. The waveform in this
case has a positive phase with a 100% on-state. 0% duty output is performed when the data
register value is set to the same value as TGRA_3. The waveform in this case has a positive phase
with a 100% off-state.
On and off compare-matches occur simultaneously, but if a turn-on compare-match and turn-off
compare-match for the same phase occur simultaneously, both compare-matches are ignored and
the waveform does not change.
(l) Toggle Output Synchronized with PWM Cycle
In complementary PWM mode, toggle output can be performed in synchronization with the PWM
carrier cycle by setting the PSYE bit to 1 in the timer output control register (TOCR). An example
of a toggle output waveform is shown in figure 10.54.
This output is toggled by a compare-match between TCNT_3 and TGRA_3 and a compare-match
between TCNT4 and H'0000.
The output pin for this toggle output is the TIOC3A pin. The initial output is 1.

(m) Counter Clearing by Another Channel
In complementary PWM mode, by setting a mode for synchronization with another channel by
means of the timer synchronous register (TSYR), and selecting synchronous clearing with bits
CCLR2 to CCLR0 in the timer control register (TCR), it is possible to have TCNT_3, TCNT_4,
and TCNTS cleared by another channel.
Figure 10.55 illustrates the operation.
Use of this function enables counter clearing and restarting to be performed by means of an
external signal.

(n) Output Waveform Control at Synchronous Counter Clearing in Complementary PWM
Mode
Setting the WRE bit in TWCR to 1 suppresses initial output when synchronous counter clearing
occurs in the Tb interval at the trough in complementary PWM mode and controls abrupt change
in duty cycle at synchronous counter clearing.
Initial output suppression is applicable only when synchronous clearing occurs in the Tb interval
at the trough as indicated by (10) or (11) in figure 10.56. When synchronous clearing occurs
outside that interval, the initial value specified by the OLS bits in TOCR is output. Even in the Tb
interval at the trough, if synchronous clearing occurs in the initial value output period (indicated
by (1) in figure 10.56) immediately after the counters start operation, initial value output is not
suppressed.
This function can be used in both the MTU2 and MTU2S. In the MTU2, synchronous clearing
generated in channels 0 to 2 in the MTU2 can cause counter clearing in complementary PWM
mode; in the MTU2S, compare match or input capture flag setting in channels 0 to 2 in the MTU2
can cause counter clearing.

by the MTU2.
Synchronous counter clearing is suppressed only within the interval shown in figure 10.62. When
using this function, the MTU2S should be set to complementary PWM mode.

when bit SCC is modified from 0 to 1, the synchronous

synchronous clearing may be suppressed.

(p) Counter Clearing by TGRA_3 Compare Match
In complementary PWM mode, by setting the CCE bit in the timer waveform control register
(TWCR), it is possible to have TCNT_3, TCNT_4, and TCNTS cleared by TGRA_3 compare
match.
Figure 10.68 illustrates an operation example.

(q) Example of AC Synchronous Motor (Brushless DC Motor) Drive Waveform Output
In complementary PWM mode, a brushless DC motor can easily be controlled using the timer gate
control register (TGCR). Figures 10.69 to 10.72 show examples of brushless DC motor drive
waveforms created using TGCR.
When output phase switching for a 3-phase brushless DC motor is performed by means of external
signals detected with a Hall element, etc., clear the FB bit in TGCR to 0. In this case, the external
signals indicating the polarity position are input to channel 0 timer input pins TIOC0A, TIOC0B,
and TIOC0C (set with PFC). When an edge is detected at pin TIOC0A, TIOC0B, or TIOC0C, the
output on/off state is switched automatically.
When the FB bit is 1, the output on/off state is switched when the UF, VF, or WF bit in TGCR is
cleared to 0 or set to 1.
The drive waveforms are output from the complementary PWM mode 6-phase output pins. With
this 6-phase output, in the case of on output, it is possible to use complementary PWM mode
output and perform chopping output by setting the N bit or P bit to 1. When the N bit or P bit is 0,
level output is selected.
The 6-phase output active level (on output level) can be set with the OLSN and OLSP bits in the
timer output control register (TOCR) regardless of the setting of the N and P bits.

(r) A/D Converter Start Request Setting
In complementary PWM mode, an A/D converter start request can be issued using a TGRA_3
compare-match, TCNT_4 underflow (trough), or compare-match on a channel other than channels
3 and 4.
When start requests using a TGRA_3 compare-match are specified, A/D conversion can be started
at the crest of the TCNT_3 count.
A/D converter start requests can be set by setting the TTGE bit to 1 in the timer interrupt enable
register (TIER). To issue an A/D converter start request at a TCNT_4 underflow (trough), set the
TTGE2 bit in TIER_4 to 1.

(3) Interrupt Skipping in Complementary PWM Mode
Interrupts TGIA_3 (at the crest) and TCIV_4 (at the trough) in channels 3 and 4 can be skipped up
to seven times by making settings in the timer interrupt skipping set register (TITCR).
Transfers from a buffer register to a temporary register or a compare register can be skipped in
coordination with interrupt skipping by making settings in the timer buffer transfer register
(TBTER). For the linkage with buffer registers, refer to description (c), Buffer Transfer Control
Linked with Interrupt Skipping, below.
A/D converter start requests generated by the A/D converter start request delaying function can
also be skipped in coordination with interrupt skipping by making settings in the timer A/D
converter request control register (TADCR). For the linkage with the A/D converter start request
delaying function, refer to section 10.4.9, A/D Converter Start Request Delaying Function.
The setting of the timer interrupt skipping setting register (TITCR) must be done while the
TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along
with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never
occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to
clear the skipping counter.
(a) Example of Interrupt Skipping Operation Setting Procedure
Figure 10.73 shows an example of the interrupt skipping operation setting procedure. Figure 10.74
shows the periods during which interrupt skipping count can be changed.

Note: The setting of TITCR must be done while the
TGIA_3 and TCIV_4 interrupt requests are
disabled by the settings of TIER_3
and TIER_4 along with under the conditions in
which TGFA_3 and TCFV_4 flag settings by

(c) Buffer Transfer Control Linked with Interrupt Skipping
In complementary PWM mode, whether to transfer data from a buffer register to a temporary
register and whether to link the transfer with interrupt skipping can be specified with the BTE1
and BTE0 bits in the timer buffer transfer set register (TBTER).
Figure 10.76 shows an example of operation when buffer transfer is suppressed (BTE1 = 0 and
BTE0 = 1). While this setting is valid, data is not transferred from the buffer register to the
temporary register.
Figure 10.77 shows an example of operation when buffer transfer is linked with interrupt skipping
(BTE1 = 1 and BET0 = 0). While this setting is valid, data is not transferred from the buffer
register outside the buffer transfer-enabled period.
There are two types of timing in which data is transferred from the buffer register to the temporary
register or to general register, depending on the buffer register modification timing after an
interrupt occurrence.
Note that the buffer transfer-enabled period depends on the T3AEN and T4VEN bit settings in the
timer interrupt skipping set register (TITCR). Figure 10.78 shows the relationship between the
T3AEN and T4VEN bit settings in TITCR and buffer transfer-enabled period.
Note: This function must always be used in combination with interrupt skipping.
When interrupt skipping is disabled (the T3AEN and T4VEN bits in the timer interrupt
skipping set register (TITCR) are cleared to 0 or the skipping count set bits (3ACOR and
4VCOR) in TITCR are cleared to 0), make sure that buffer transfer is not linked with
interrupt skipping (clear the BTE1 bit in the timer buffer transfer set register (TBTER) to
0). If buffer transfer is linked with interrupt skipping while interrupt skipping is disabled,
buffer transfer is never performed.

(4) Complementary PWM Mode Output Protection Function
Complementary PWM mode output has the following protection functions.
(a) Register and counter miswrite prevention function
With the exception of the buffer registers, which can be rewritten at any time, access by the CPU
can be enabled or disabled for the mode registers, control registers, compare registers, and
counters used in complementary PWM mode by means of the RWE bit in the timer read/write
enable register (TRWER). The applicable registers are some (21 in total) of the registers in
channels 3 and 4 shown in the following:
• TCR_3 and TCR_4, TMDR_3 and TMDR_4, TIORH_3 and TIORH_4, TIORL_3 and
TIORL_4, TIER_3 and TIER_4, TCNT_3 and TCNT_4, TGRA_3 and TGRA_4, TGRB_3
and TGRB_4, TOER, TOCR, TGCR, TCDR, and TDDR.
This function enables miswriting due to CPU runaway to be prevented by disabling CPU access to
the mode registers, control registers, and counters. When the applicable registers are read in the
access-disabled state, undefined values are returned. Writing to these registers is ignored.
(b) Halting of PWM output by external signal
The 6-phase PWM output pins can be set automatically to the high-impedance state by inputting
specified external signals. There are four external signal input pins.
See section 12, Port Output Enable 2 (POE2), for details.

10.4.9 A/D Converter Start Request Delaying Function
A/D converter start requests can be issued in channel 4 by making settings in the timer A/D
converter start request control register (TADCR), timer A/D converter start request cycle set
registers (TADCORA_4 and TADCORB_4), and timer A/D converter start request cycle set
buffer registers (TADCOBRA_4 and TADCOBRB_4).
The A/D converter start request delaying function compares TCNT_4 with TADCORA_4 or
TADCORB_4, and when their values match, the function issues a respective A/D converter start
request (TRG4AN or TRG4BN).
A/D converter start requests (TRG4AN and TRG4BN) can be skipped in coordination with
interrupt skipping by making settings in the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in
TADCR.

Notes: 1. Perform TADCR setting while TCNT_4 is stopped.
2. Do not set BF1 to 1 when complementary PWM mode
is not selected.
3. Do not set ITA3AE, ITA4VE, ITB3AE, ITB4VE,

buffer registers (TADCOBRA_4 and TADCOBRB_4). Data is transferred from the buffer
registers to the respective cycle set registers at the timing selected with the BF1 and BF0 bits
in the timer A/D converter start request control register (TADCR_4).

the counter, clear the corresponding bit in TSTR to 0
directly.
2. To start channels 3 and 4 in reset-synchronized PWM

[4] When the capture condition specified in TIOR is satisfied,
the TCNT_5 value is captured in TGR_5.
[5] For U-phase dead time compensation, when an interrupt is
generated at the crest (TGIA_3) or trough (TCIV_4) in
complementary PWM mode, read the TGRU_5 value,
calculate the difference in time in TGRB_3, and write the
corrected value to TGRD_3 in the interrupt processing.
For the V phase and W phase, read the TGRV_5 and
TGRW_5 values and write the corrected values to TGRC_4
and TGRD_4, respectively, in the same way as for U-phase
compensation.
The TCNT_5 value should be cleared through the
TCNTCMPCLR setting or by software.
Notes: The PFC settings must be completed in advance.
* As an interrupt flag is set under the capture condition
specified in TIOR, do not enable interrupt requests in
TIER_5.

10.4.13 TCNT Capture at Crest and/or Trough in Complementary PWM Operation
The TCNT value is captured in TGR at either the crest or trough or at both the crest and trough
during complementary PWM operation. The timing for capturing in TGR can be selected by
TIOR.
Figure 10.92 shows an example in which TCNT is used as a free-running counter without being
cleared, and the TCNT value is captured in TGR at the specified timing (either crest or trough, or
both crest and trough).

10.5 Interrupt Sources
10.5.1 Interrupt Sources and Priorities
There are three kinds of MTU2 interrupt source; TGR input capture/compare match, TCNT
overflow, and TCNT underflow. Each interrupt source has its own status flag and enable/disabled
bit, allowing the generation of interrupt request signals to be enabled or disabled individually.
When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the
corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The
interrupt request is cleared by clearing the status flag to 0.
Relative channel priorities can be changed by the interrupt controller, however the priority order
within a channel is fixed. For details, see section 6, Interrupt Controller (INTC).
Table 10.57 lists the MTU2 interrupt sources.

REJ09B0344-0300
(1) Input Capture/Compare Match Interrupt
An interrupt is requested if the TGIE bit in TIER is set to 1 when the TGF flag in TSR is set to 1
by the occurrence of a TGR input capture/compare match on a particular channel. The interrupt
request is cleared by clearing the TGF flag to 0. The MTU2 has 21 input capture/compare match
interrupts, six for channel 0, four each for channels 3 and 4, two each for channels 1 and 2, and
three for channel 5. The TGFE_0 and TGFF_0 flags in channel 0 are not set by the occurrence of
an input capture.
(2) Overflow Interrupt
An interrupt is requested if the TCIEV bit in TIER is set to 1 when the TCFV flag in TSR is set to
1 by the occurrence of TCNT overflow on a channel. The interrupt request is cleared by clearing
the TCFV flag to 0. The MTU2 has five overflow interrupts, one for each channel.
(3) Underflow Interrupt
An interrupt is requested if the TCIEU bit in TIER is set to 1 when the TCFU flag in TSR is set to
1 by the occurrence of TCNT underflow on a channel. The interrupt request is cleared by clearing
the TCFU flag to 0. The MTU2 has two underflow interrupts, one each for channels 1 and 2.
10.5.2 DMAC Activation
The DMAC can be activated by the TGRA input capture/compare match interrupt in each channel.
For details, see section 9, Direct Memory Access Controller (DMAC).
In the MTU2, a total of five TGRA input capture/compare match interrupts can be used as DMAC
activation sources, one each for channels 0 to 4.

REJ09B0344-0300
10.5.3 A/D Converter Activation
The A/D converter can be activated by one of the following three methods in the MTU2. Table
10.58 shows the relationship between interrupt sources and A/D converter start request signals.
(1) A/D Converter Activation by TGRA Input Capture/Compare Match or at TCNT_4
Trough in Complementary PWM Mode
The A/D converter can be activated by the occurrence of a TGRA input capture/compare match in
each channel. In addition, if complementary PWM operation is performed while the TTGE2 bit in
TIER_4 is set to 1, the A/D converter can be activated at the trough of TCNT_4 count (TCNT_4 =
H'0000).
A/D converter start request signal TRGAN is issued to the A/D converter under either one of the
following conditions.
• When the TGFA flag in TSR is set to 1 by the occurrence of a TGRA input capture/compare
match on a particular channel while the TTGE bit in TIER is set to 1
• When the TCNT_4 count reaches the trough (TCNT_4 = H'0000) during complementary
PWM operation while the TTGE2 bit in TIER_4 is set to 1
When either condition is satisfied, if A/D converter start signal TRGAN from the MTU2 is
selected as the trigger in the A/D converter, A/D conversion will start.
(2) A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0
The A/D converter can be activated by generating A/D converter start request signal TRG0N
when a compare match occurs between TCNT_0 and TGRE_0 in channel 0.
When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between
TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter
start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from the
MTU2 is selected as the trigger in the A/D converter, A/D conversion will start.
Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
Rev. 3.00 Mar. 04, 2009 Page 537 of 1168
REJ09B0344-0300
(3) A/D Converter Activation by A/D Converter Start Request Delaying Function
The A/D converter can be activated by generating A/D converter start request signal TRG4AN or
TRG4BN when the TCNT_4 count matches the TADCORA or TADCORB value if the TAD4AE
or TAD4BE bit in the A/D converter start request control register (TADCR) is set to 1. For details,
refer to section 10.4.9, A/D Converter Start Request Delaying Function.
A/D conversion will start if A/D converter start signal TRG4AN from the MTU2 is selected as the
trigger in the A/D converter when TRG4AN is generated or if TRG4BN from the MTU2 is
selected as the trigger in the A/D converter when TRG4BN is generated.

(2) Output Compare Output Timing
A compare match signal is generated in the final state in which TCNT and TGR match (the point
at which the count value matched by TCNT is updated). When a compare match signal is
generated, the output value set in TIOR is output at the output compare output pin (TIOC pin).
After a match between TCNT and TGR, the compare match signal is not generated until the
TCNT input clock is generated.
Figure 10.97 shows output compare output timing (normal mode and PWM mode) and figure

10.7 Usage Notes
10.7.1 Module Standby Mode Setting
MTU2 operation can be disabled or enabled using the standby control register. The initial setting
is for MTU2 operation to be halted. Register access is enabled by clearing module standby mode.
For details, refer to section 23, Power-Down Modes.
10.7.2 Input Clock Restrictions
The input clock pulse width must be at least 1.5 states in the case of single-edge detection, and at
least 2.5 states in the case of both-edge detection. The MTU2 will not operate properly at narrower
pulse widths.
In phase counting mode, the phase difference and overlap between the two input clocks must be at
least 1.5 states, and the pulse width must be at least 2.5 states. Figure 10.118 shows the input clock
conditions in phase counting mode.

10.7.3 Caution on Period Setting
When counter clearing on compare match is set, TCNT is cleared in the final state in which it
matches the TGR value (the point at which the count value matched by TCNT is updated).
Consequently, the actual counter frequency is given by the following formula:
• Channel 0 to 4
f =
Pφ
(N + 1)
• Channel 5
f =
Pφ
N
Where f: Counter frequency
Pφ: Peripheral clock operating frequency
N: TGR set value
10.7.4 Contention between TCNT Write and Clear Operations
If the counter clear signal is generated in the T2 state of a TCNT write cycle, TCNT clearing takes
precedence and the TCNT write is not performed.

10.7.12 TCNT2 Write and Overflow/Underflow Contention in Cascade Connection
With timer counters TCNT1 and TCNT2 in a cascade connection, when a contention occurs
during TCNT_1 count (during a TCNT_2 overflow/underflow) in the T2 state of the TCNT_2
write cycle, the write to TCNT_2 is conducted, and the TCNT_1 count signal is disabled. At this
point, if there is match with TGRA_1 and the TCNT_1 value, a compare signal is issued.
Furthermore, when the TCNT_1 count clock is selected as the input capture source of channel 0,
TGRA_0 to D_0 carry out the input capture operation. In addition, when the compare match/input
capture is selected as the input capture source of TGRB_1, TGRB_1 carries out input capture
operation. The timing is shown in figure 10.129.
For cascade connections, be sure to synchronize settings for channels 1 and 2 when setting TCNT
clearing.

10.7.13 Counter Value during Complementary PWM Mode Stop
When counting operation is suspended with TCNT_3 and TCNT_4 in complementary PWM
mode, TCNT_3 has the timer dead time register (TDDR) value, and TCNT_4 is held at H'0000.
When restarting complementary PWM mode, counting begins automatically from the initialized
state. This explanatory diagram is shown in figure 10.130.
When counting begins in another operating mode, be sure that TCNT_3 and TCNT_4 are set to
the initial values.

In complementary PWM mode, conduct rewrites by buffer operation for the PWM cycle setting
register (TGRA_3), timer cycle data register (TCDR), and duty setting registers (TGRB_3,
TGRA_4, and TGRB_4).
In complementary PWM mode, channel 3 and channel 4 buffers operate in accordance with bit
settings BFA and BFB of TMDR_3. When TMDR_3's BFA bit is set to 1, TGRC_3 functions as a
buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for
TGRA_4, and TCBR functions as the TCDR's buffer register.

10.7.15 Reset Sync PWM Mode Buffer Operation and Compare Match Flag
When setting buffer operation for reset sync PWM mode, set the BFA and BFB bits of TMDR_4
to 0. The TIOC4C pin will be unable to produce its waveform output if the BFA bit of TMDR_4 is
set to 1.
In reset sync PWM mode, the channel 3 and channel 4 buffers operate in accordance with the BFA
and BFB bit settings of TMDR_3. For example, if the BFA bit of TMDR_3 is set to 1, TGRC_3
functions as the buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer
register for TGRA_4.
The TGFC bit and TGFD bit of TSR_3 and TSR_4 are not set when TGRC_3 and TGRD_3 are
operating as buffer registers.
Figure 10.131 shows an example of operations for TGR_3, TGR_4, TIOC3, and TIOC4, with
TMDR_3's BFA and BFB bits set to 1, and TMDR_4's BFA and BFB bits set to 0.

10.7.16 Overflow Flags in Reset Synchronous PWM Mode
When set to reset synchronous PWM mode, TCNT_3 and TCNT_4 start counting when the CST3
bit of TSTR is set to 1. At this point, TCNT_4's count clock source and count edge obey the
TCR_3 setting.
In reset synchronous PWM mode, with cycle register TGRA_3's set value at H'FFFF, when
specifying TGR3A compare-match for the counter clear source, TCNT_3 and TCNT_4 count up
to H'FFFF, then a compare-match occurs with TGRA_3, and TCNT_3 and TCNT_4 are both
cleared. At this point, TSR's overflow flag TCFV bit is not set.
Figure 10.132 shows a TCFV bit operation example in reset synchronous PWM mode with a set
value for cycle register TGRA_3 of H'FFFF, when a TGRA_3 compare-match has been specified
without synchronous setting for the counter clear source.

10.7.19 Cautions on Transition from Normal Operation or PWM Mode 1 to Reset-
Synchronized PWM Mode
When making a transition from channel 3 or 4 normal operation or PWM mode 1 to reset-
synchronized PWM mode, if the counter is halted with the output pins (TIOC3B, TIOC3D,
TIOC4A, TIOC4C, TIOC4B, TIOC4D) in the high-level state, followed by the transition to reset-
synchronized PWM mode and operation in that mode, the initial pin output will not be correct.
When making a transition from normal operation to reset-synchronized PWM mode, write H'11 to
registers TIORH_3, TIORL_3, TIORH_4, and TIORL_4 to initialize the output pins to low level
output, then set an initial register value of H'00 before making the mode transition.
When making a transition from PWM mode 1 to reset-synchronized PWM mode, first switch to
normal operation, then initialize the output pins to low level output and set an initial register value
of H'00 before making the transition to reset-synchronized PWM mode.
Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
Rev. 3.00 Mar. 04, 2009 Page 565 of 1168
REJ09B0344-0300
10.7.20 Output Level in Complementary PWM Mode and Reset-Synchronized PWM Mode
When channels 3 and 4 are in complementary PWM mode or reset-synchronized PWM mode, the
PWM waveform output level is set with the OLSP and OLSN bits in the timer output control
register (TOCR). In the case of complementary PWM mode or reset-synchronized PWM mode,
TIOR should be set to H'00.
10.7.21 Interrupts in Module Standby Mode
If module standby mode is entered when an interrupt has been requested, it will not be possible to
clear the CPU interrupt source or the DMAC activation source. Interrupts should therefore be
disabled before entering module standby mode.
10.7.22 Simultaneous Capture of TCNT_1 and TCNT_2 in Cascade Connection
When timer counters 1 and 2 (TCNT_1 and TCNT_2) are operated as a 32-bit counter in cascade
connection, the cascade counter value cannot be captured successfully even if input-capture input
is simultaneously done to TIOC1A and TIOC2A or to TIOC1B and TIOC2B. This is because the
input timing of TIOC1A and TIOC2A or of TIOC1B and TIOC2B may not be the same when
external input-capture signals to be input into TCNT_1 and TCNT_2 are taken in synchronization
with the internal clock. For example, TCNT_1 (the counter for upper 16 bits) does not capture the
count-up value by overflow from TCNT_2 (the counter for lower 16 bits) but captures the count
value before the count-up. In this case, the values of TCNT_1 = H'FFF1 and TCNT_2 = H'0000
should be transferred to TGRA_1 and TGRA_2 or to TGRB_1 and TGRB_2, but the values of
TCNT_1 = H'FFF0 and TCNT_2 = H'0000 are erroneously transferred.
The MTU2 additionally supports the function that can capture TCNT_1 and TCNT_2
simultaneously via a single input capture input. This function allows 32-bit counter fetches
without TCNT_1 and TCNT_2 capture timing deviation. For details, see section 10.3.8, Timer
Input Capture Control Register (TICCR).

10.8 MTU2 Output Pin Initialization
10.8.1 Operating Modes
The MTU2 has the following six operating modes. Waveform output is possible in all of these
modes.
• Normal mode (channels 0 to 4)
• PWM mode 1 (channels 0 to 4)
• PWM mode 2 (channels 0 to 2)
• Phase counting modes 1 to 4 (channels 1 and 2)
• Complementary PWM mode (channels 3 and 4)
• Reset-synchronized PWM mode (channels 3 and 4)
The MTU2 output pin initialization method for each of these modes is described in this section.
10.8.2 Reset Start Operation
The MTU2 output pins (TIOC*) are initialized low by a reset and in standby mode. Since MTU2
pin function selection is performed by the pin function controller (PFC), when the PFC is set, the
MTU2 pin states at that point are output to the ports. When MTU2 output is selected by the PFC
immediately after a reset, the MTU2 output initial level, low, is output directly at the port. When
the active level is low, the system will operate at this point, and therefore the PFC setting should
be made after initialization of the MTU2 output pins is completed.
Note: Channel number and port notation are substituted for *.

REJ09B0344-0300
10.8.3 Operation in Case of Re-Setting Due to Error During Operation, etc.
If an error occurs during MTU2 operation, MTU2 output should be cut by the system. Cutoff is
performed by switching the pin output to port output with the PFC and outputting the inverse of
the active level. For large-current pins, output can also be cut by hardware, using port output
enable (POE). The pin initialization procedures for re-setting due to an error during operation, etc.,
and the procedures for restarting in a different mode after re-setting, are shown below.
The MTU2 has six operating modes, as stated above. There are thus 36 mode transition
combinations, but some transitions are not available with certain channel and mode combinations.
Possible mode transition combinations are shown in table 10.59.

10.8.4 Overview of Initialization Procedures and Mode Transitions in Case of Error
during Operation, etc.
• When making a transition to a mode (Normal, PWM1, PWM2, PCM) in which the pin output
level is selected by the timer I/O control register (TIOR) setting, initialize the pins by means of
a TIOR setting.
• In PWM mode 1, since a waveform is not output to the TIOC*B (TIOC*D) pin, setting TIOR
will not initialize the pins. If initialization is required, carry it out in normal mode, then switch
to PWM mode 1.
• In PWM mode 2, since a waveform is not output to the cycle register pin, setting TIOR will
not initialize the pins. If initialization is required, carry it out in normal mode, then switch to
PWM mode 2.
• In normal mode or PWM mode 2, if TGRC and TGRD operate as buffer registers, setting
TIOR will not initialize the buffer register pins. If initialization is required, clear buffer mode,
carry out initialization, then set buffer mode again.
• In PWM mode 1, if either TGRC or TGRD operates as a buffer register, setting TIOR will not
initialize the TGRC pin. To initialize the TGRC pin, clear buffer mode, carry out initialization,
then set buffer mode again.
• When making a transition to a mode (CPWM, RPWM) in which the pin output level is
selected by the timer output control register (TOCR) setting, switch to normal mode and
perform initialization with TIOR, then restore TIOR to its initial value, and temporarily disable
channel 3 and 4 output with the timer output master enable register (TOER). Then operate the
unit in accordance with the mode setting procedure (TOCR setting, TMDR setting, TOER
setting).
Note: Channel number is substituted for * indicated in this article.
Pin initialization procedures are described below for the numbered combinations in table 10.59.
The active level is assumed to be low.

Section 11 Multi-Function Timer Pulse Unit 2S (MTU2S)
This LSI has an on-chip multi-function timer pulse unit 2S (MTU2S) that comprises three 16-bit
timer channels. The MTU2S includes channels 3 to 5 of the MTU2. For details, refer to section 10,
Multi-Function Timer Pulse Unit 2 (MTU2). The MTU2S operates on Mφ clock (MTU clock)
while the MTU2 operates on Pφ clock (peripheral clock) thus the term Pφ in the MTU2
corresponds to Mφ in the MTU2S. To distinguish from the MTU2, "S" is added to the end of the
MTU2S input/output pin and register names. For example, TIOC3A is called TIOC3AS and
TGRA_3 is called TGRA_3S in this section.
The MTU2S can operate at 80 MHz max. for complementary PWM output functions or at 40 MHz
max. for the other functions.

Section 12 Port Output Enable 2 (POE2)
The port output enable 2 (POE2) can be used to place the high-current pins (PB18/TIOC3B,
PB19/TIOC3D, PB4/TIOC4A, PB5/TIOC4B, PB6/TIOC4C, PB7/TIOC4D, PB12/TIOC4AS,
PB13/TIOC4BS, PB10/TIOC4CS, PB11/TIOC4DS, PB21/TIOC3BS, and PB20/TIOC3DS) and
the pins for channel 0 of the MTU2 (PA22/TIOC0A, PA23/TIOC0B, PA24/TIOC0C, and
PA25/TIOC0D) in high-impedance state, depending on the change on the POE0, POE1, POE3,
POE4, POE7, and POE8 input pins and the output status of the high-current pins, or by modifying
register settings. It can also simultaneously generate interrupt requests.
Section 12 Port Output Enable 2 (POE2)
Rev. 3.00 Mar. 04, 2009 Page 608 of 1168
REJ09B0344-0300
12.1 Features
• Each of the POE0, POE1, POE3, POE4, POE7, and POE8 input pins can be set for falling
edge, Pφ/8 × 16, Pφ/16 × 16, or Pφ/128 × 16 low-level sampling.
• High-current pins and the pins for channel 0 of the MTU2 can be placed in high-impedance
state by POE0, POE1, POE3, POE4, POE7, and POE8 pin falling-edge or low-level sampling.
• High-current pins can be placed in high-impedance state when the high-current pin output
levels are compared and simultaneous active-level output continues for one cycle or more.
• High-current pins and the pins for channel 0 of the MTU2 can be placed in high-impedance
state by modifying the POE2 register settings.
• Interrupts can be generated by input-level sampling or output-level comparison results.
The POE2 has input level detection circuits, output level comparison circuits, and a high-
impedance request/interrupt request generating circuit as shown in the block diagram of figure
12.1.

Output The high-current pins for the MTU2 are placed in
high-impedance state when the pins
simultaneously output an active level for one or
more cycles of the peripheral clock (Pφ). (In the
case of TOCS = 0 in timer output control register 1
(TOCR1) in the MTU2, low level when the output
level select P (OLSP) bit is 0, or high level when
the OLSP bit is 1. In the case of TOCS = 1, low
level when the OLS3N, OLS3P, OLS2N, OLS2P,
OLS1N, and OLS1P bits are 0 in TOCR2, or high
level when these bits are 1.)
This active level comparison is done when the
MTU2 output function or general output function is
selected in the pin function controller. If another
function is selected, the output level is not
checked.
Pin combinations for output comparison and high-
impedance control can be selected by POE2
registers.

12.4.1 Input Level Detection Operation
If the input conditions set by ICSR1 to ICSR3 occur on the POE0, POE1, POE3, POE4, POE7,
and POE8 pins, the high-current pins and the pins for channel 0 of the MTU2 are placed in high-
impedance state. Note however, that these high-current and MTU2 pins enter high-impedance
state only when general input/output function, MTU2 function, or MTU2S function is selected for
these pins.
(1) Falling Edge Detection
When a change from a high to low level is input to the POE0, POE1, POE3, POE4, POE7, and
POE8 pins, the high-current pins and the pins for channel 0 of the MTU2 are placed in high-
impedance state.
Figure 12.2 shows the sample timing after the level changes in input to the POE0, POE1, POE3,
POE4, POE7, and POE8 pins until the respective pins enter high-impedance state.

(2) Low-Level Detection
Figure 12.3 shows the low-level detection operation. Sixteen continuous low levels are sampled
with the sampling clock selected by ICSR1 to ICSR3. If even one high level is detected during this
interval, the low level is not accepted.
The timing when the high-current pins enter the high-impedance state after the sampling clock is
input is the same in both falling-edge detection and in low-level detection.

12.4.3 Release from High-Impedance State
High-current pins that have entered high-impedance state due to input-level detection can be
released either by returning them to their initial state with a power-on reset, or by clearing all of
the flags in bits 15 to 12 (POE8F, POE7F, POE4F, POE3F, POE1F, and POE0F) of ICSR1 to
ICSR3. However, note that when low-level sampling is selected by bits 7 to 0 in ICSR1 to ICSR3,
just writing 0 to a flag is ignored (the flag is not cleared); flags can be cleared by writing 0 to it
only after a high level is input to one of the POE0, POE1, POE3, POE4, POE7, and POE8 pins
and is sampled.
High-current pins that have entered high-impedance state due to output-level detection can be
released either by returning them to their initial state with a power-on reset, or by clearing the flag
in bit 15 (OCF1 and OCF2) in OCSR1 and OCSR2. However, note that just writing 0 to a flag is
ignored (the flag is not cleared); flags can be cleared only after an inactive level is output from the
high-current pins. Inactive-level outputs can be achieved by setting the MTU2 and MTU2S
internal registers.

12.6 Usage Note
12.6.1 Pin Status When the WDT Issues a Power-On Reset
When a power-on reset is issued by the WDT, the pin function controller (PFC) is initialized and
the I/O ports function as general inputs (initial value).
If a power-on reset is issued by the WDT during high-impedance processing by the port output
enable (POE) signal, the I/O port pins are placed in output state for a time period of one cycle of
the peripheral clock, Pφ, until the pin functions switch to general inputs.
If a power-on reset is issued by the WDT during high-impedance processing by MTU2 or MTU2S
short detection, the I/O port pins are placed in the same status as described above.
Figure 12.5 shows the I/O port pin status when a power-on reset is issued by the WDT during
high-impedance processing by the POE input while the timer output is selected.

13.3 Operation
13.3.1 Interval Count Operation
When an internal clock is selected with the CKS[1:0] bits in CMCSR and the STR bit in CMSTR
is set to 1, CMCNT starts incrementing using the selected clock. When the values in CMCNT and
CMCOR match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. When the
CMIE bit in CMCSR is set to 1 at this time, a compare match interrupt (CMI) is requested.
CMCNT then starts counting up again from H'0000.
Figure 13.2 shows the operation of the compare match counter.

13.4 Interrupts
13.4.1 Interrupt Sources and DMA Transfer Requests
The CMT has channels and each of them to which a different vector address is allocated has a
compare match interrupt. When both the interrupt request flag (CMF) and the interrupt enable bit
(CMIE) are set to 1, the corresponding interrupt request is output. When the interrupt is used to
activate a CPU interrupt, the priority of channels can be changed by the interrupt controller
settings. For details, see section 6, Interrupt Controller (INTC).
Clear the CMF bit to 0 by the user exception handling routine. If this operation is not carried out,
another interrupt will be generated. The direct memory access controller (DMAC) can be set to be
activated when a compare match interrupt is requested. In this case, an interrupt is not issued to
the CPU. If the setting to activate the DMAC has not been made, an interrupt request is sent to the
CPU. The CMF bit is automatically cleared to 0 when data is transferred by the DMAC.
13.4.2 Timing of Compare Match Flag Setting
When CMCOR and CMCNT match, a compare match signal is generated at the last state in which
the values match (the timing when the CMCNT value is updated to H'0000) and the CMF bit in
CMCSR is set to 1. That is, after a match between CMCOR and CMCNT, the compare match
signal is not generated until the next CMCNT counter clock input. Figure 13.4 shows the timing of
CMF bit setting.

Section 14 Watchdog Timer (WDT)
This LSI includes the watchdog timer (WDT), which externally outputs an overflow signal
(WDTOVF) on overflow of the counter when the value of the counter has not been updated
because of a system malfunction. The WDT can simultaneously generate an internal reset signal
for the entire LSI.
The WDT is a single channel timer that counts up the clock oscillation settling period when the
system leaves software standby mode or the temporary standby periods that occur when the clock
frequency is changed. It can also be used as a general watchdog timer or interval timer.
14.1 Features
• Can be used to ensure the clock oscillation settling time
The WDT is used in leaving software standby mode or the temporary standby periods that
occur when the clock frequency is changed.
• Can switch between watchdog timer mode and interval timer mode.
• Outputs WDTOVF signal in watchdog timer mode
When the counter overflows in watchdog timer mode, the WDTOVF signal is output
externally. It is possible to select whether to reset the LSI internally when this happens. Either
the power-on reset or manual reset signal can be selected as the internal reset type.
• Interrupt generation in interval timer mode
An interval timer interrupt is generated when the counter overflows.
• Choice of eight counter input clocks
Eight clocks (Pφ × 1 to Pφ × 1/16384) that are obtained by dividing the peripheral clock can be
selected.

14.3.1 Watchdog Timer Counter (WTCNT)
WTCNT is an 8-bit readable/writable register that is incremented by cycles of the selected clock
signal. When an overflow occurs, it generates a watchdog timer overflow signal (WDTOVF) in
watchdog timer mode and an interrupt in interval timer mode. WTCNT is initialized to H'00 by a
power-on reset caused by the RES pin or in software standby mode.
Use word access to write to WTCNT, writing H'5A in the upper byte. Use byte access to read
from WTCNT.
Note: The method for writing to WTCNT differs from that for other registers to prevent
erroneous writes. See section 14.3.4, Notes on Register Access, for details.

WTCSR is initialized to H'18 by a power-on reset caused by the RES pin or in software standby
mode. When used to count the clock oscillation settling time for canceling software standby mode,
it retains its value after counter overflow.
Use word access to write to WTCSR, writing H'A5 in the upper byte. Use byte access to read from

14.3.3 Watchdog Reset Control/Status Register (WRCSR)
WRCSR is an 8-bit readable/writable register that controls output of the internal reset signal
generated by watchdog timer counter (WTCNT) overflow.
WRCSR is initialized to H'1F by input of a reset signal from the RES pin, but is not initialized by
the internal reset signal generated by overflow of the WDT. WRCSR is initialized to H'1F in
software standby mode.
Note: The method for writing to WRCSR differs from that for other registers to prevent
erroneous writes. See section 14.3.4, Notes on Register Access, for details.

14.3.4 Notes on Register Access
The watchdog timer counter (WTCNT), watchdog timer control/status register (WTCSR), and
watchdog reset control/status register (WRCSR) are more difficult to write to than other registers.
The procedures for reading or writing to these registers are given below.
(1) Writing to WTCNT and WTCSR
These registers must be written by a word transfer instruction. They cannot be written by a byte or
longword transfer instruction.
When writing to WTCNT, set the upper byte to H'5A and transfer the lower byte as the write data,
as shown in figure 14.2. When writing to WTCSR, set the upper byte to H'A5 and transfer the
lower byte as the write data. This transfer procedure writes the lower byte data to WTCNT or
WTCSR.

Rev. 3.00 Mar. 04, 2009 Page 657 of 1168
REJ09B0344-0300
(2) Writing to WRCSR
WRCSR must be written by a word access to address H'FFFE0004. It cannot be written by byte
transfer or longword transfer instructions.
Procedures for writing 0 to WOVF (bit 7) and for writing to RSTE (bit 6) and RSTS (bit 5) are
different, as shown in figure 14.3.
To write 0 to the WOVF bit, the write data must be H'A5 in the upper byte and H'00 in the lower
byte. This clears the WOVF bit to 0. The RSTE and RSTS bits are not affected. To write to the
RSTE and RSTS bits, the upper byte must be H'5A and the lower byte must be the write data. The
values of bits 6 and 5 of the lower byte are transferred to the RSTE and RSTS bits, respectively.
The WOVF bit is not affected.

(3) Reading from WTCNT, WTCSR, and WRCSR
WTCNT, WTCSR, and WRCSR are read in a method similar to other registers. WTCSR is
allocated to address H'FFFE0000, WTCNT to address H'FFFE0002, and WRCSR to address
H'FFFE0004. Byte transfer instructions must be used for reading from these registers.

14.4 WDT Usage
14.4.1 Canceling Software Standby Mode
The WDT can be used to cancel software standby mode with an interrupt such as an NMI
interrupt. The procedure is described below. (The WDT does not operate when resets are used for
canceling, so keep the RES or MRES pin low until clock oscillation settles.)
1. Before making a transition to software standby mode, always clear the TME bit in WTCSR
to 0. When the TME bit is 1, an erroneous reset or interval timer interrupt may be generated
when the count overflows.
2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the
counter in WTCNT. These values should ensure that the time till count overflow is longer than
the clock oscillation settling time.
3. After setting the STBY bit of the standby control register (STBCR: see section 23, Power-
Down Modes) to 1, the execution of a SLEEP instruction puts the system in software standby
mode and clock operation then stops.
4. The WDT starts counting by detecting the edge change of the NMI signal.
5. When the WDT count overflows, the CPG starts supplying the clock and this LSI resumes
operation. The WOVF flag in WRCSR is not set when this happens.

Rev. 3.00 Mar. 04, 2009 Page 659 of 1168
REJ09B0344-0300
14.4.2 Changing the Frequency
To change the frequency used by the PLL, use the WDT. When changing the frequency only by
switching the divider, do not use the WDT.
1. Before changing the frequency, always clear the TME bit in WTCSR to 0. When the TME bit
is 1, an erroneous reset or interval timer interrupt may be generated when the count overflows.
2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the
counter in WTCNT. These values should ensure that the time till count overflow is longer than
the clock oscillation settling time.
3. When the frequency control register (FRQCR) is written to, this LSI stops temporarily. The
WDT starts counting.
4. When the WDT count overflows, the CPG resumes supplying the clock and this LSI resumes
operation. The WOVF flag in WRCSR is not set when this happens.
5. The counter stops at the value of H'00.
6. Before changing WTCNT after execution of the frequency change instruction, always confirm
that the value of WTCNT is H'00 by reading from WTCNT.

Rev. 3.00 Mar. 04, 2009 Page 660 of 1168
REJ09B0344-0300
14.4.3 Using Watchdog Timer Mode
1. Set the WT/IT bit in WTCSR to 1, the type of count clock in the CKS[2:0] bits in WTCSR,
whether this LSI is to be reset internally or not in the RSTE bit in WRCSR, the reset type if it
is generated in the RSTS bit in WRCSR, and the initial value of the counter in WTCNT.
2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode.
3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent
the counter from overflowing.
4. When the counter overflows, the WDT sets the WOVF flag in WRCSR to 1, and the
WDTOVF signal is output externally (figure 14.4). The WDTOVF signal can be used to reset
the system. The WDTOVF signal is output for 64 × Pφ clock cycles.
5. If the RSTE bit in WRCSR is set to 1, a signal to reset the inside of this LSI can be generated
simultaneously with the WDTOVF signal. Either power-on reset or manual reset can be
selected for this interrupt by the RSTS bit in WRCSR. The internal reset signal is output for
128 × Pφ clock cycles.
6. When a WDT overflow reset is generated simultaneously with a reset input on the RES pin,
the RES pin reset takes priority, and the WOVF bit in WRCSR is cleared to 0.

14.4.4 Using Interval Timer Mode
When operating in interval timer mode, interval timer interrupts are generated at every overflow of
the counter. This enables interrupts to be generated at set periods.
1. Clear the WT/IT bit in WTCSR to 0, set the type of count clock in the CKS[2:0] bits in
WTCSR, and set the initial value of the counter in WTCNT.
2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode.
3. When the counter overflows, the WDT sets the IOVF bit in WTCSR to 1 and an interval timer
interrupt request is sent to the INTC. The counter then resumes counting.

14.5 Usage Notes
Pay attention to the following points when using the WDT in either the interval timer or watchdog
timer mode.
14.5.1 Timer Variation
After timer operation has started, the period from the power-on reset point to the first count up
timing of WTCNT varies depending on the time period that is set by the TME bit of WTCSR. The
shortest such time period is thus one cycle of the peripheral clock, Pφ, while the longest is the
result of frequency division according to the value in the CKS[2:0] bits. The timing of subsequent
incrementation is in accord with the selected frequency division ratio. Accordingly, this time
difference is referred to as timer variation.
This also applies to the timing of the first incrementation after WTCNT has been written to during
timer operation.
14.5.2 Prohibition against Setting H'FF to WTCNT
When the value in WTCNT reaches H'FF, the WDT assumes that an overflow has occurred.
Accordingly, when H'FF is set in WTCNT, an interval timer interrupt or WDT reset will occur
immediately, regardless of the current clock selection by the CKS[2:0] bits.
14.5.3 System Reset by WDTOVF Signal
If the WDTOVF signal is input to the RES pin of this LSI, this LSI cannot be initialized correctly.
Avoid input of the WDTOVF signal to the RES pin of this LSI through glue logic circuits. To
reset the entire system with the WDTOVF signal, use the circuit shown in figure 14.6.

REJ09B0344-0300
14.5.4 Manual Reset in Watchdog Timer Mode
When a manual reset occurs in watchdog timer mode, the bus cycle is continued. If a manual reset
occurs while the bus is released or during DMAC burst transfer, manual reset exception handling
will be pended until the CPU acquires the bus mastership.
However, if the duration from generation of the manual reset to the bus cycle end is equal to or
longer than the duration of the internal manual reset activated, the occurrence of the internal
manual reset source is ignored instead of being pended, and the manual reset exception handling is
not executed.

Section 15 Serial Communication Interface with FIFO
(SCIF)
This LSI has a four-channel serial communication interface with FIFO (SCIF) that supports both
asynchronous and clocked synchronous serial communication. It also has 16-stage FIFO registers
for both transmission and reception independently for each channel that enable this LSI to perform
efficient high-speed continuous communication.
15.1 Features
• Asynchronous serial communication:
⎯ Serial data communication is performed by start-stop in character units. The SCIF can
communicate with a universal asynchronous receiver/transmitter (UART), an asynchronous
communication interface adapter (ACIA), or any other communications chip that employs
a standard asynchronous serial system. There are eight selectable serial data
communication formats.
⎯ Data length: 7 or 8 bits
⎯ Stop bit length: 1 or 2 bits
⎯ Parity: Even, odd, or none
⎯ Receive error detection: Parity, framing, and overrun errors
⎯ Break detection: Break is detected when a framing error is followed by at least one frame at
the space 0 level (low level). It is also detected by reading the RXD level directly from the
serial port register when a framing error occurs.
• Clocked synchronous serial communication:
⎯ Serial data communication is synchronized with a clock signal. The SCIF can communicate
with other chips having a clocked synchronous communication function. There is one serial
data communication format.
⎯ Data length: 8 bits
⎯ Receive error detection: Overrun errors
• Full duplex communication: The transmitting and receiving sections are independent, so the
SCIF can transmit and receive simultaneously. Both sections use 16-stage FIFO buffering, so
high-speed continuous data transfer is possible in both the transmit and receive directions.
• On-chip baud rate generator with selectable bit rates
• Internal or external transmit/receive clock source: From either baud rate generator (internal) or
SCK pin (external)
Section 15 Serial Communication Interface with FIFO (SCIF)
Rev. 3.00 Mar. 04, 2009 Page 666 of 1168
REJ09B0344-0300
• Four types of interrupts: Transmit-FIFO-data-empty interrupt, break interrupt, receive-FIFO-
data-full interrupt, and receive-error interrupts are requested independently.
• When the SCIF is not in use, it can be stopped by halting the clock supplied to it, saving
power.
• The quantity of data in the transmit and receive FIFO data registers and the number of receive
errors of the receive data in the receive FIFO data register can be ascertained.
• A time-out error (DR) can be detected when receiving in asynchronous mode.
Figure 15.1 shows a block diagram of the SCIF.

15.3.1 Receive Shift Register (SCRSR)
SCRSR receives serial data. Data input at the RXD pin is loaded into SCRSR in the order
received, LSB (bit 0) first, converting the data to parallel form. When one byte has been received,
it is automatically transferred to the receive FIFO data register (SCFRDR).
The CPU cannot read or write to SCRSR directly.

15.3.2 Receive FIFO Data Register (SCFRDR)
SCFRDR is a register that stores serial receive data. The SCIF completes the reception of one byte
of serial data by moving the received data from the receive shift register (SCRSR) into SCFRDR
for storage. Continuous reception is possible until 16 bytes are stored. The CPU can read but not
write to SCFRDR. If data is read when there is no receive data in the SCFRDR, the value is
undefined.
When SCFRDR is full of receive data, subsequent serial data is lost.
SCFRDR is initialized to an undefined value by a power-on reset.

15.3.3 Transmit Shift Register (SCTSR)
SCTSR transmits serial data. The SCIF loads transmit data from the transmit FIFO data register
(SCFTDR) into SCTSR, then transmits the data serially from the TXD pin, LSB (bit 0) first. After
transmitting one data byte, the SCIF automatically loads the next transmit data from SCFTDR into
SCTSR and starts transmitting again.
The CPU cannot read or write to SCTSR directly.

15.3.4 Transmit FIFO Data Register (SCFTDR)
SCFTDR is a 16-byte FIFO register that stores data for serial transmission. When the SCIF detects
that the transmit shift register (SCTSR) is empty, it moves transmit data written in the SCFTDR
into SCTSR and starts serial transmission. Continuous serial transmission is performed until there
is no transmit data left in SCFTDR. The CPU can write to SCFTDR at all times.
When SCFTDR is full of transmit data (16 bytes), no more data can be written. If writing of new
data is attempted, the data is ignored.
SCFTDR is initialized to an undefined value by a power-on reset.

5 PE 0 R/W Parity Enable
Selects whether to add a parity bit to transmit data and
to check the parity of receive data, in asynchronous
mode. In clocked synchronous mode, a parity bit is
neither added nor checked, regardless of the PE setting.
0: Parity bit not added or checked
1: Parity bit added and checked*
Note: * When PE is set to 1, an even or odd parity bit is
added to transmit data, depending on the parity
mode (O/E) setting. Receive data parity is
checked according to the even/odd (O/E) mode
setting.
4 O/E 0 R/W Parity mode
Selects even or odd parity when parity bits are added
and checked. The O/E setting is used only in
asynchronous mode and only when the parity enable bit
(PE) is set to 1 to enable parity addition and checking.
The O/E setting is ignored in clocked synchronous
mode, or in asynchronous mode when parity addition
and checking is disabled.
0: Even parity*1
1: Odd parity*2
Notes: 1. If even parity is selected, the parity bit is
added to transmit data to make an even
number of 1s in the transmitted character and
parity bit combined. Receive data is checked
to see if it has an even number of 1s in the
received character and parity bit combined.
2. If odd parity is selected, the parity bit is added
to transmit data to make an odd number of 1s
in the transmitted character and parity bit
combined. Receive data is checked to see if it
has an odd number of 1s in the received
character and parity bit combined.

3 STOP 0 R/W Stop Bit Length
Selects one or two bits as the stop bit length in
asynchronous mode. This setting is used only in
asynchronous mode. It is ignored in clocked
synchronous mode because no stop bits are added.
When receiving, only the first stop bit is checked,
regardless of the STOP bit setting. If the second stop
bit is 1, it is treated as a stop bit, but if the second stop
bit is 0, it is treated as the start bit of the next incoming
character.
0: One stop bit
When transmitting, a single 1-bit is added at the end
of each transmitted character.

15.3.7 Serial Status Register (SCFSR)
SCFSR is a 16-bit register. The upper 8 bits indicate the number of receive errors in the receive
FIFO data register, and the lower 8 bits indicate the status flag indicating SCIF operating state.
The CPU can always read and write to SCFSR, but cannot write 1 to the status flags (ER, TEND,
TDFE, BRK, RDF, and DR). These flags can be cleared to 0 only if they have first been read
(after being set to 1). Bits 3 (FER) and 2 (PER) are read-only bits that cannot be written.

0: Receiving is in progress or has ended normally
[Clearing conditions]
• ER is cleared to 0 a power-on reset
• ER is cleared to 0 when the chip is when 0 is
written after 1 is read from ER
1: A framing error or parity error has occurred.
[Setting conditions]
• ER is set to 1 when the stop bit is 0 after checking
whether or not the last stop bit of the received
data is 1 at the end of one data receive
operation*2
• ER is set to 1 when the total number of 1s in the
receive data plus parity bit does not match the
even/odd parity specified by the O/E bit in SCSMR
Notes: 1. Clearing the RE bit to 0 in SCSCR does
not affect the ER bit, which retains its
previous value. Even if a receive error
occurs, the receive data is transferred to
SCFRDR and the receive operation is
continued. Whether or not the data read
from SCFRDR includes a receive error
can be detected by the FER and PER bits
in SCFSR.

the maximum quantity of data that can be
written when TDFE is 1 is "16 minus the
specified transmission trigger number". If an
attempt is made to write additional data, the
data is ignored. The quantity of data in
SCFTDR is indicated by the upper 8 bits of

15.3.8 Bit Rate Register (SCBRR)
SCBRR is an 8-bit register that, together with the baud rate generator clock source selected by the
CKS[1:0] bits in the serial mode register (SCSMR), determines the serial transmit/receive bit rate.
The CPU can always read and write to SCBRR. SCBRR is initialized to H'FF by a power-on reset.
Each channel has independent baud rate generator control, so different values can be set in four
channels.

15.4 Operation
15.4.1 Overview
For serial communication, the SCIF has an asynchronous mode in which characters are
synchronized individually, and a clocked synchronous mode in which communication is
synchronized with clock pulses.
The SCIF has a 16-stage FIFO buffer for both transmission and receptions, reducing the overhead
of the CPU, and enabling continuous high-speed communication.
The transmission format is selected in the serial mode register (SCSMR), as shown in table 15.9.
The SCIF clock source is selected by the combination of the CKE1 and CKE0 bits in the serial
control register (SCSCR), as shown in table 15.10.
(1) Asynchronous Mode
• Data length is selectable: 7 or 8 bits
• Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding
selections constitutes the communication format and character length.
• In receiving, it is possible to detect framing errors, parity errors, receive FIFO data full,
overrun errors, receive data ready, and breaks.
• The number of stored data bytes is indicated for both the transmit and receive FIFO registers.
• An internal or external clock can be selected as the SCIF clock source.
⎯ When an internal clock is selected, the SCIF operates using the clock of on-chip baud rate
generator.
⎯ When an external clock is selected, the external clock input must have a frequency 16 times
the bit rate. (The on-chip baud rate generator is not used.)
(2) Clocked Synchronous Mode
• The transmission/reception format has a fixed 8-bit data length.
• In receiving, it is possible to detect overrun errors (ORER).
• An internal or external clock can be selected as the SCIF clock source.
⎯ When an internal clock is selected, the SCIF operates using the clock of the on-chip baud
rate generator, and outputs this clock to external devices as the synchronous clock.
⎯ When an external clock is selected, the SCIF operates on the input synchronous clock not
using the on-chip baud rate generator.

15.4.2 Operation in Asynchronous Mode
In asynchronous mode, each transmitted or received character begins with a start bit and ends with
a stop bit. Serial communication is synchronized one character at a time.
The transmitting and receiving sections of the SCIF are independent, so full duplex
communication is possible. The transmitter and receiver are 16-byte FIFO buffered, so data can be
written and read while transmitting and receiving are in progress, enabling continuous transmitting
and receiving.
Figure 15.2 shows the general format of asynchronous serial communication.
In asynchronous serial communication, the communication line is normally held in the mark
(high) state. The SCIF monitors the line and starts serial communication when the line goes to the
space (low) state, indicating a start bit. One serial character consists of a start bit (low), data (LSB
first), parity bit (high or low), and stop bit (high), in that order.
When receiving in asynchronous mode, the SCIF synchronizes at the falling edge of the start bit.
The SCIF samples each data bit on the eighth pulse of a clock with a frequency 16 times* the bit
rate. Receive data is latched at the center of each bit.

times the bit rate becomes the basic clock, and receive data is sampled at the fourth
rising edge of the basic clock.

(2) Clock
An internal clock generated by the on-chip baud rate generator or an external clock input from the
SCK pin can be selected as the SCIF transmit/receive clock. The clock source is selected by the
C/A bit in the serial mode register (SCSMR) and bits CKE[1:0] in the serial control register
(SCSCR). For clock source selection, refer to table 15.10, SCSMR and SCSCR Settings and SCIF
Clock Source Selection.
When an external clock is input at the SCK pin, it must have a frequency equal to 16 times the
desired bit rate.
When the SCIF operates on an internal clock, it can output a clock signal on the SCK pin. The
frequency of this output clock is 16 times the desired bit rate.

(3) Transmitting and Receiving Data
• SCIF Initialization (Asynchronous Mode)
Before transmitting or receiving, clear the TE and RE bits to 0 in the serial control register
(SCSCR), then initialize the SCIF as follows.
When changing the operating mode or the communication format, always clear the TE and RE bits
to 0 before following the procedure given below. Clearing TE to 0 initializes the transmit shift
register (SCTSR). Clearing TE and RE to 0, however, does not initialize the serial status register
(SCFSR), transmit FIFO data register (SCFTDR), or receive FIFO data register (SCFRDR), which
retain their previous contents. Clear TE to 0 after all transmit data has been transmitted and the
TEND flag in the SCFSR is set. The TE bit can be cleared to 0 during transmission, but the
transmit data goes to the Mark state after the bit is cleared to 0. Set the TFRST bit in SCFCR to 1
and reset SCFTDR before TE is set again to start transmission.
When an external clock is used, the clock should not be stopped during initialization or subsequent
operation. SCIF operation becomes unreliable if the clock is stopped.

Set data transfer format in SCSMR
Set value in SCBRR
Set ABCS in SCSEMR
Set RTRG[1:0] and TTRG[1:0] in SCFCR,
and clear TFRST and RFRST
Set TE and RE bits in SCSCR to 1,
and set TIE, RIE, and REIE bits
End of initialization
Set the clock selection in SCSCR.
Be sure to clear bits TIE, RIE, TE,
and RE to 0.
Set the data transfer format in
SCSMR.
Write a value corresponding to the
bit rate into SCBRR. (Not
necessary if an external clock is
used.)
Set the TE bit or RE bit in SCSCR
to 1. Also set the RIE, REIE, and
TIE bits. Setting the TE and RE bits
enables the TxD and RxD pins to be
used.
When transmitting, the SCIF will go
to the mark state; when receiving,
it will go to the idle state, waiting for
a start bit.

REJ09B0344-0300
In serial transmission, the SCIF operates as described below.
1. When data is written into the transmit FIFO data register (SCFTDR), the SCIF transfers the
data from SCFTDR to the transmit shift register (SCTSR) and starts transmitting. Confirm that
the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to
SCFTDR. The number of data bytes that can be written is (16 – transmit trigger setting).
2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive
transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the
FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register
(SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is
generated.
The serial transmit data is sent from the TXD pin in the following order.
A. Start bit: One-bit 0 is output.
B. Transmit data: 8-bit or 7-bit data is output in LSB-first order.
C. Parity bit: One parity bit (even or odd parity) is output. (A format in which a parity bit is
not output can also be selected.)
D. Stop bit(s): One or two 1 bits (stop bits) are output.
E. Mark state: 1 is output continuously until the start bit that starts the next transmission is
sent.
3. The SCIF checks the SCFTDR transmit data at the timing for sending the stop bit. If data is
present, the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial
transmission of the next frame is started.

Error handling
[1] Receive error handling and

Read the DR, ER, and BRK
flags in SCFSR, and the
ORER flag in SCLSR, to
identify any error, perform the
appropriate error handling,
then clear the DR, ER, BRK,
and ORER flags to 0. In the
case of a framing error, a
break can also be detected by
reading the value of the RxD
pin.
[2] SCIF status check and receive
data read:
Read SCFSR and check that
RDF flag = 1, then read the
receive data in SCFRDR, read
1 from the RDF flag, and then
clear the RDF flag to 0. The
transition of the RDF flag from
0 to 1 can be identified by an
RXI interrupt.
[3] Serial reception continuation
procedure:
To continue serial reception,
read at least the receive
trigger set number of receive
data bytes from SCFRDR,
read 1 from the RDF flag, then
clear the RDF flag to 0. The
number of receive data bytes
in SCFRDR can be
ascertained by reading from
SCRFDR.

Whether a framing error or parity error
has occurred in the receive data that
is to be read from the receive FIFO
data register (SCFRDR) can be
ascertained from the FER and PER
bits in the serial status register
(SCFSR).
•
When a break signal is received,
receive data is not transferred to
SCFRDR while the BRK flag is set.
However, note that the last data in
SCFRDR is H'00, and the break data
in which a framing error occurred is
stored.

In serial reception, the SCIF operates as described below.
1. The SCIF monitors the transmission line, and if a 0 start bit is detected, performs internal
synchronization and starts reception.
2. The received data is stored in SCRSR in LSB-to-MSB order.
3. The parity bit and stop bit are received.
After receiving these bits, the SCIF carries out the following checks.
A. Stop bit check: The SCIF checks whether the stop bit is 1. If there are two stop bits, only
the first is checked.
B. The SCIF checks whether receive data can be transferred from the receive shift register
(SCRSR) to SCFRDR.
C. Overrun check: The SCIF checks that the ORER flag is 0, indicating that the overrun error
has not occurred.
D. Break check: The SCIF checks that the BRK flag is 0, indicating that the break state is not
set.
If all the above checks are passed, the receive data is stored in SCFRDR.
Note: When a parity error or a framing error occurs, reception is not suspended.
4. If the RIE bit in SCSCR is set to 1 when the RDF or DR flag changes to 1, a receive-FIFO-
data-full interrupt (RXI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to
1 when the ER flag changes to 1, a receive-error interrupt (ERI) request is generated. If the
RIE bit or the REIE bit in SCSCR is set to 1 when the BRK or ORER flag changes to 1, a
break reception interrupt (BRI) request is generated.
Figure 15.8 shows an example of the operation for reception.

15.4.3 Operation in Clocked Synchronous Mode
In clocked synchronous mode, the SCIF transmits and receives data in synchronization with clock
pulses. This mode is suitable for high-speed serial communication.
The SCIF transmitter and receiver are independent, so full-duplex communication is possible
while sharing the same clock. The transmitter and receiver are also 16-byte FIFO buffered, so
continuous transmitting or receiving is possible by reading or writing data while transmitting or
receiving is in progress.
Figure 15.9 shows the general format in clocked synchronous serial communication.

REJ09B0344-0300
In clocked synchronous serial communication, each data bit is output on the communication line
from one falling edge of the serial clock to the next. Data is guaranteed valid at the rising edge of
the serial clock.
In each character, the serial data bits are transmitted in order from the LSB (first) to the MSB
(last). After output of the MSB, the communication line remains in the state of the MSB.
In clocked synchronous mode, the SCIF receives data by synchronizing with the rising edge of the
serial clock.
(1) Transmit/Receive Formats
The data length is fixed at eight bits. No parity bit can be added.
(2) Clock
An internal clock generated by the on-chip baud rate generator by the setting of the C/A bit in
SCSMR and CKE[1:0] in SCSCR, or an external clock input from the SCK pin can be selected as
the SCIF transmit/receive clock.
When the SCIF operates on an internal clock, it outputs the clock signal at the SCK pin. Eight
clock pulses are output per transmitted or received character. When the SCIF is not transmitting or
receiving, the clock signal remains in the high state. When only receiving, the clock signal outputs
while the RE bit of SCSCR is 1 and the number of data in receive FIFO is more than the receive
FIFO data trigger number.
(3) Transmitting and Receiving Data
• SCIF Initialization (Clocked Synchronous Mode)
Before transmitting, receiving, or changing the mode or communication format, the software must
clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize the SCIF.
Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing RE to 0, however, does
not initialize the RDF, PER, FER, and ORER flags and receive data register (SCRDR), which
retain their previous contents.

RIE, TE, and RE bits to 0.
Set the data transfer format in
SCSMR.
Set CKE[1:0].
Write a value corresponding to
the bit rate into SCBRR. This
is not necessary if an external
clock is used.
Set the TE or RE bit in SCSCR
to 1. Also set the TIE, RIE, and
REIE bits to enable the TXD,
RXD, and SCK pins to be used.
When transmitting, the TXD pin
will go to the mark state.
When receiving in clocked
synchronous mode with the
synchronization clock output (clock
master) selected, a clock starts to
be output from the SCK pin at this
point.

REJ09B0344-0300
In serial transmission, the SCIF operates as described below.
1. When data is written into the transmit FIFO data register (SCFTDR), the SCIF transfers the
data from SCFTDR to the transmit shift register (SCTSR) and starts transmitting. Confirm that
the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to
SCFTDR. The number of data bytes that can be written is (16 – transmit trigger setting).
2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive
transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the
FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register
(SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is
generated.
If clock output mode is selected, the SCIF outputs eight synchronous clock pulses. If an
external clock source is selected, the SCIF outputs data in synchronization with the input
clock. Data is output from the TXD pin in order from the LSB (bit 0) to the MSB (bit 7).
3. The SCIF checks the SCFTDR transmit data at the timing for sending the MSB (bit 7). If data
is present, the data is transferred from SCFTDR to SCTSR, and then serial transmission of the
next frame is started. If there is no data, the TXD pin holds the state after the TEND flag in
SCFSR is set to 1 and the MSB (bit 7) is sent.
4. After the end of serial transmission, the SCK pin is held in the high state.
Figure 15.12 shows an example of SCIF transmit operation.

In serial reception, the SCIF operates as described below.
1. The SCIF synchronizes with serial clock input or output and starts the reception.
2. Receive data is shifted into SCRSR in order from the LSB to the MSB. After receiving the
data, the SCIF checks the receive data can be loaded from SCRSR into SCFRDR or not. If this
check is passed, the RDF flag is set to 1 and the SCIF stores the received data in SCFRDR. If
the check is not passed (overrun error is detected), further reception is prevented.
3. After setting RDF to 1, if the receive FIFO data full interrupt enable bit (RIE) is set to 1 in
SCSCR, the SCIF requests a receive-data-full interrupt (RXI). If the ORER bit is set to 1 and
the receive-data-full interrupt enable bit (RIE) or the receive error interrupt enable bit (REIE)
in SCSCR is also set to 1, the SCIF requests a break interrupt (BRI).

15.5 SCIF Interrupts
The SCIF has four interrupt sources: transmit-FIFO-data-empty (TXI), receive-error (ERI),
receive FIFO data full (RXI), and break (BRI).
Table 15.12 shows the interrupt sources and their order of priority. The interrupt sources are
enabled or disabled by means of the TIE, RIE, and REIE bits in SCSCR. A separate interrupt
request is sent to the interrupt controller for each of these interrupt sources.
When a TXI request is enabled by the TIE bit and the TDFE flag in the serial status register
(SCFSR) is set to 1, a TXI interrupt request is generated. The DMAC can be activated and data
transfer performed by this TXI interrupt request. At this time, an interrupt request is not sent to the
CPU.
When an RXI request is enabled by the RIE bit and the RDFE flag or the DR flag in SCFSR is set
to 1, an RXI interrupt request is generated. The DMAC can be activated and data transfer
performed by this RXI interrupt request. At this time, an interrupt request is not sent to the CPU.
The RXI interrupt request caused by the DR flag is generated only in asynchronous mode.
When the RIE bit is set to 0 and the REIE bit is set to 1, the SCIF requests only an ERI interrupt
without requesting an RXI interrupt.
The TXI interrupt indicates that transmit data can be written, and the RXI interrupt indicates that
there is receive data in SCFRDR.

15.6 Usage Notes
Note the following when using the SCIF.
15.6.1 SCFTDR Writing and TDFE Flag
The TDFE flag in the serial status register (SCFSR) is set when the number of transmit data bytes
written in the transmit FIFO data register (SCFTDR) has fallen below the transmit trigger number
set by bits TTRG[1:0] in the FIFO control register (SCFCR). After the TDFE flag is set, transmit
data up to the number of empty bytes in SCFTDR can be written, allowing efficient continuous
transmission.
However, if the number of data bytes written in SCFTDR is equal to or less than the transmit
trigger number, the TDFE flag will be set to 1 again after being read as 1 and cleared to 0. TDFE
flag clearing should therefore be carried out when SCFTDR contains more than the transmit
trigger number of transmit data bytes.
The number of transmit data bytes in SCFTDR can be found from the upper 8 bits of the FIFO
data count register (SCFDR).
15.6.2 SCFRDR Reading and RDF Flag
The RDF flag in the serial status register (SCFSR) is set when the number of receive data bytes in
the receive FIFO data register (SCFRDR) has become equal to or greater than the receive trigger
number set by bits RTRG[1:0] in the FIFO control register (SCFCR). After RDF flag is set,
receive data equivalent to the trigger number can be read from SCFRDR, allowing efficient
continuous reception.
However, if the number of data bytes in SCFRDR exceeds the trigger number, the RDF flag will
be set to 1 again if it is cleared to 0. The RDF flag should therefore be cleared to 0 after being read
as 1 after reading the number of the received data in the receive FIFO data register (SCFRDR)
which is less than the trigger number.
The number of receive data bytes in SCFRDR can be found from the lower 8 bits of the FIFO data
count register (SCFDR).
Section 15 Serial Communication Interface with FIFO (SCIF)
Rev. 3.00 Mar. 04, 2009 Page 722 of 1168
REJ09B0344-0300
15.6.3 Restriction on DMAC Usage
When the DMAC writes data to SCFTDR due to a TXI interrupt request, the state of the TEND
flag becomes undefined. Therefore, the TEND flag should not be used as the transfer end flag in
such a case.
15.6.4 Break Detection and Processing
Break signals can be detected by reading the RXD pin directly when a framing error (FER) is
detected. In the break state the input from the RXD pin consists of all 0s, so the FER flag is set
and the parity error flag (PER) may also be set.
Note that, although transfer of receive data to SCFRDR is halted in the break state, the SCIF
receiver continues to operate.
15.6.5 Sending a Break Signal
The I/O condition and level of the TXD pin are determined by the SPB2IO and SPB2DT bits in
the serial port register (SCSPTR). This feature can be used to send a break signal.
Until TE bit is set to 1 (enabling transmission) after initializing, the TXD pin does not work.
During the period, mark status is performed by the SPB2DT bit. Therefore, the SPB2IO and
SPB2DT bits should be set to 1 (high level output).
To send a break signal during serial transmission, clear the SPB2DT bit to 0 (designating low
level), then clear the TE bit to 0 (halting transmission). When the TE bit is cleared to 0, the
transmitter is initialized regardless of the current transmission state, and 0 is output from the TXD
pin.

15.6.6 Receive Data Sampling Timing and Receive Margin (Asynchronous Mode)
The SCIF operates on a base clock with a frequency of 16 times the transfer rate. In reception, the
SCIF synchronizes internally with the fall of the start bit, which it samples on the base clock.
Receive data is latched at the rising edge of the eighth base clock pulse.* The timing is shown in
figure 15.17.

The receive margin in asynchronous mode can therefore be expressed as shown in equation 1.

M = (0.5 − ) − (L − 0.5) F −(1 + F) × 100 %

2N
D − 0.5

Where: M: Receive margin (%)
N: Ratio of clock frequency to bit rate
(N = 16 when ABCS = 0, and N = 8 when ABCS = 1)
D: Clock duty (D = 0 to 1.0)
L: Frame length (L = 9 to 12)
F: Absolute deviation of clock frequency
From equation 1, if F = 0, D = 0.5, and N = 16, the receive margin is 46.875%, as given by
equation 2.
Equation 2:
When D = 0.5 and F = 0:
M = (0.5 − 1/(2 × 16)) × 100%
= 46.875%
This is a theoretical value. A reasonable margin to allow in system designs is 20% to 30%.
15.6.7 FER and PER Flags in the Serial Status Register (SCFSR)
The FER (framing error) and PER (parity error) flags in the serial status register (SCFSR) are
status flags of the receive FIFO data register (SCFRDR) to be read next. If the CPU or DMAC
reads the receive FIFO data register, the FER (framing error) and PER (parity error) flags of the
current receive data will be lost. To check the framing error and parity error status of the current
receive data correctly, the serial status register (SCFSR) should be read before the receive FIFO
data register is read.

Section 16 I2C Bus Interface 3 (IIC3)
The I2C bus interface 3 conforms to and provides a subset of the Philips I2C (Inter-IC) bus
interface functions. However, the configuration of the registers that control the I2C bus differs
partly from the Philips register configuration.
16.1 Features
• Selection of I2C format or clocked synchronous serial format
• Continuous transmission/reception
Since the shift register, transmit data register, and receive data register are independent from
each other, the continuous transmission/reception can be performed.
I2C bus format:
• Start and stop conditions generated automatically in master mode
• Selection of acknowledge output levels when receiving
• Automatic loading of acknowledge bit when transmitting
• Bit synchronization/wait function
In master mode, the state of SCL is monitored per bit, and the timing is synchronized
automatically. If transmission/reception is not yet possible, set the SCL to low until
preparations are completed.
• Six interrupt sources
Transmit data empty (including slave-address match), transmit end, receive data full (including
slave-address match), arbitration lost, NACK detection, and stop condition detection
• The direct memory access controller (DMAC) can be activated by a transmit-data-empty
request or receive-data-full request to transfer data.
• Direct bus drive
Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive
function is selected.
Clocked synchronous serial format:
• Four interrupt sources
Transmit-data-empty, transmit-end, receive-data-full, and overrun error
• The direct memory access controller (DMAC) can be activated by a transmit-data-empty
request or receive-data-full request to transfer data.

16.3.8 I2C Bus Receive Data Register (ICDRR)
ICDRR is an 8-bit register that stores the receive data. When data of one byte is received, ICDRR
transfers the receive data from ICDRS to ICDRR and the next data can be received. ICDRR is a
receive-only register, therefore the CPU cannot write to this register.
ICDRR is initialized to H'FF by a power-on reset.

16.3.9 I2C Bus Shift Register (ICDRS)
ICDRS is a register that is used to transfer/receive data. In transmission, data is transferred from
ICDRT to ICDRS and the data is sent from the SDA pin. In reception, data is transferred from
ICDRS to ICDRR after data of one byte is received. This register cannot be read directly from the
CPU.

16.4.2 Master Transmit Operation
In master transmit mode, the master device outputs the transmit clock and transmit data, and the
slave device returns an acknowledge signal. For master transmit mode operation timing, refer to
figures 16.5 and 16.6. The transmission procedure and operations in master transmit mode are
described below.
1. Set the ICE bit in ICCR1 to 1. Also, set the bits CKS[3:0] in ICCR1. (Initial setting)
2. Read the BBSY flag in ICCR2 to confirm that the bus is released. Set the MST and TRS bits in
ICCR1 to select master transmit mode. Then, write 1 to BBSY and 0 to SCP. (Start condition
issued) This generates the start condition.
3. After confirming that TDRE in ICSR has been set, write the transmit data (the first byte data
show the slave address and R/W) to ICDRT. At this time, TDRE is automatically cleared to 0,
and data is transferred from ICDRT to ICDRS. TDRE is set again.
4. When transmission of one byte data is completed while TDRE is 1, TEND in ICSR is set to 1
at the rise of the 9th transmit clock pulse. Read the ACKBR bit in ICIER, and confirm that the
slave device has been selected. Then, write second byte data to ICDRT. When ACKBR is 1,
the slave device has not been acknowledged, so issue the stop condition. To issue the stop
condition, write 0 to BBSY and SCP. SCL is fixed low until the transmit data is prepared or
the stop condition is issued.
5. The transmit data after the second byte is written to ICDRT every time TDRE is set.
6. Write the number of bytes to be transmitted to ICDRT. Wait until TEND is set (the end of last
byte data transmission) while TDRE is 1, or wait for NACK (NACKF in ICSR = 1) from the
receive device while ACKE in ICIER is 1. Then, issue the stop condition to clear TEND or
NACKF.
7. When the STOP bit in ICSR is set to 1, the operation returns to slave receive mode.

16.4.3 Master Receive Operation
In master receive mode, the master device outputs the receive clock, receives data from the slave
device, and returns an acknowledge signal. For master receive mode operation timing, refer to
figures 16.7 and 16.8. The reception procedure and operations in master receive mode are shown
below.
1. Clear the TEND bit in ICSR to 0, then clear the TRS bit in ICCR1 to 0 to switch from master
transmit mode to master receive mode. Then, clear the TDRE bit to 0.
2. When ICDRR is read (dummy data read), reception is started, and the receive clock is output,
and data received, in synchronization with the internal clock. The master device outputs the
level specified by ACKBT in ICIER to SDA, at the 9th receive clock pulse.
3. After the reception of first frame data is completed, the RDRF bit in ICSR is set to 1 at the rise
of 9th receive clock pulse. At this time, the receive data is read by reading ICDRR, and RDRF
is cleared to 0.
4. The continuous reception is performed by reading ICDRR every time RDRF is set. If 8th
receive clock pulse falls after reading ICDRR by the other processing while RDRF is 1, SCL is
fixed low until ICDRR is read.
5. If next frame is the last receive data, set the RCVD bit in ICCR1 to 1 before reading ICDRR.
This enables the issuance of the stop condition after the next reception.
6. When the RDRF bit is set to 1 at rise of the 9th receive clock pulse, issue the stage condition.
7. When the STOP bit in ICSR is set to 1, read ICDRR. Then clear the RCVD bit to 0.
8. The operation returns to slave receive mode.
Note: If only one byte is received, read ICDRR (dummy-read) after the RCVD bit in ICCR1 is
set.

16.4.4 Slave Transmit Operation
In slave transmit mode, the slave device outputs the transmit data, while the master device outputs
the receive clock and returns an acknowledge signal. For slave transmit mode operation timing,
refer to figures 16.9 and 16.10.
The transmission procedure and operations in slave transmit mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and
TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches.
2. When the slave address matches in the first frame following detection of the start condition,
the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th
clock pulse. At this time, if the 8th bit data (R/W) is 1, the TRS bit in ICCR1 and the TDRE bit
in ICSR are set to 1, and the mode changes to slave transmit mode automatically. The
continuous transmission is performed by writing transmit data to ICDRT every time TDRE is
set.
3. If TDRE is set after writing last transmit data to ICDRT, wait until TEND in ICSR is set to 1,
with TDRE = 1. When TEND is set, clear TEND.
4. Clear TRS for the end processing, and read ICDRR (dummy read). SCL is opened.
5. Clear TDRE.

16.4.5 Slave Receive Operation
In slave receive mode, the master device outputs the transmit clock and transmit data, and the
slave device returns an acknowledge signal. For slave receive mode operation timing, refer to
figures 16.11 and 16.12. The reception procedure and operations in slave receive mode are
described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and
TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches.
2. When the slave address matches in the first frame following detection of the start condition,
the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th
clock pulse. At the same time, RDRF in ICSR is set to read ICDRR (dummy read). (Since the
read data show the slave address and R/W, it is not used.)
3. Read ICDRR every time RDRF is set. If 8th receive clock pulse falls while RDRF is 1, SCL is
fixed low until ICDRR is read. The change of the acknowledge before reading ICDRR, to be
returned to the master device, is reflected to the next transmit frame.
4. The last byte data is read by reading ICDRR.

16.4.6 Clocked Synchronous Serial Format
This module can be operated with the clocked synchronous serial format, by setting the FS bit in
SAR to 1. When the MST bit in ICCR1 is 1, the transfer clock output from SCL is selected. When
MST is 0, the external clock input is selected.
(1) Data Transfer Format
Figure 16.13 shows the clocked synchronous serial transfer format.
The transfer data is output from the fall to the fall of the SCL clock, and the data at the rising edge
of the SCL clock is guaranteed. The MLS bit in ICMR sets the order of data transfer, in either the
MSB first or LSB first. The output level of SDA can be changed during the transfer wait, by the
SDAO bit in ICCR2.

(2) Transmit Operation
In transmit mode, transmit data is output from SDA, in synchronization with the fall of the transfer
clock. The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For
transmit mode operation timing, refer to figure 16.14. The transmission procedure and operations
in transmit mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set the MST and CKS[3:0] bits in ICCR1. (Initial setting)
2. Set the TRS bit in ICCR1 to select transmit mode. Then, TDRE in ICSR is set.
3. Confirm that TDRE has been set. Then, write the transmit data to ICDRT. The data is
transferred from ICDRT to ICDRS, and TDRE is set automatically. The continuous
transmission is performed by writing data to ICDRT every time TDRE is set. When changing
from transmit mode to receive mode, clear TRS while TDRE is 1.

(3) Receive Operation
In receive mode, data is latched at the rise of the transfer clock. The transfer clock is output when
MST in ICCR1 is 1, and is input when MST is 0. For receive mode operation timing, refer to
figure 16.15. The reception procedure and operations in receive mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. When the transfer clock is output, set MST to 1 to start outputting the receive clock.
3. When the receive operation is completed, data is transferred from ICDRS to ICDRR and
RDRF in ICSR is set. When MST = 1, the next byte can be received, so the clock is
continually output. The continuous reception is performed by reading ICDRR every time
RDRF is set. When the 8th clock is risen while RDRF is 1, the overrun is detected and
AL/OVE in ICSR is set. At this time, the previous reception data is retained in ICDRR.
4. To stop receiving when MST = 1, set RCVD in ICCR1 to 1, then read ICDRR. Then, SCL is
fixed high after receiving the next byte data.

REJ09B0344-0300
Notes: Follow the steps below to receive only one byte with MST = 1 specified. See figure 16.16
for the operation timing.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. Set MST = 1 while the RCVD bit in ICCR1 is 0. This causes the receive clock to be
output.
3. Check if the BC2 bit in ICMR is set to 1 and then set the RCVD bit in ICCR1 to 1.
This causes the SCL to be fixed to the high level after outputting one byte of the
receive clock.

16.4.7 Noise Filter
The logic levels at the SCL and SDA pins are routed through noise filters before being latched
internally. Figure 16.17 shows a block diagram of the noise filter circuit.
The noise filter consists of three cascaded latches and a match detector. The SCL (or SDA) input
signal is sampled on the peripheral clock. When NF2CYC is set to 0, this signal is not passed
forward to the next circuit unless the outputs of both latches agree. When NF2CYC is set to 1, this
signal is not passed forward to the next circuit unless the outputs of three latches agree. If they do
not agree, the previous value is held.

16.5 Interrupt Requests
There are six interrupt requests in this module; transmit data empty, transmit end, receive data full,
NACK detection, STOP recognition, and arbitration lost/overrun error. Table 16.4 shows the
contents of each interrupt request.
Table 16.4 Interrupt Requests
Interrupt Request Abbreviation Interrupt Condition
I2C Bus

Clocked Synchronous
Serial Format
Transmit data Empty TXI (TDRE = 1) • (TIE = 1) √ √
Transmit end TEI (TEND = 1) • (TEIE = 1) √ √
Receive data full RXI (RDRF = 1) • (RIE = 1) √ √
STOP recognition STPI (STOP = 1) • (STIE = 1) √ ⎯
NACK detection √ ⎯
Arbitration lost/

NAKI {(NACKF = 1) + (AL = 1)} •
(NAKIE = 1) √ √
When the interrupt condition described in table 16.4 is 1, the CPU executes an interrupt exception
handling. Note that a TXI or RXI interrupt can activate the DMAC if the setting for DMAC
activation has been made. In such a case, an interrupt request is not sent to the CPU. Interrupt
sources should be cleared in the exception handling. The TDRE and TEND bits are automatically
cleared to 0 by writing the transmit data to ICDRT. The RDRF bit is automatically cleared to 0 by
reading ICDRR. The TDRE bit is set to 1 again at the same time when the transmit data is written
to ICDRT. Therefore, when the TDRE bit is cleared to 0, then an excessive data of one byte may
be transmitted.

16.6 Bit Synchronous Circuit
In master mode, this module has a possibility that high level period may be short in the two states
described below.
• When SCL is driven to low by the slave device
• When the rising speed of SCL is lowered by the load of the SCL line (load capacitance or pull-
up resistance)
Therefore, it monitors SCL and communicates by bit with synchronization.
Figure 16.22 shows the timing of the bit synchronous circuit and table 16.5 shows the time when
the SCL output changes from low to Hi-Z then SCL is monitored.

16.7 Usage Notes
16.7.1 Note on Multiple Master Usage
With multi-master used, if the transfer rate setting (CKS[3:0] in ICCR1) of I2C in this LSI is
slower than the other masters, the SCL with unexpected width may be output in rare cases.
To prevent this problem, the transfer rate of I2C should be specified as equal to or higher than
1/1.8 of the highest transfer rate among the other masters.
16.7.2 Note on Master Receive Mode
If ICDRR is read near the falling edge of 8th clock, the receive data will not be received in some
cases. In addition, if RCVD is set to 1 near the falling edge of 8th clock, a stop condition cannot
be issued in some cases. To prevent these errors, one of the following two methods should be
selected.
1. In master receive mode, ICDRR should be read before the falling edge of 8th clock.
2. In master receive mode, RCVD should be set to 1 and the processing should be performed in
byte units.
16.7.3 Note on Master Receive Mode with ACKBT Setting
In master receive mode operation, ACKBT should be set before the 8th falling edge of SCL in the
final data transfer during continuous data transfer. Otherwise, the slave device may overrun.
16.7.4 Note on MST and TRS Bit Status When an Arbitration was Lost
If the master transmission is set according to the MST and TRS bit settings while multiple masters
are used, the conflicting status in which the AL bit in ICSR is set to 1 in master transmit mode
(MST and TRS are set to 1) depending on the arbitration lost generation timing during TRS bit
handling instruction execution.
This problem can be avoided by the following methods.
• When multiple masters are used, the MST and TRS bits should be set by a MOV instruction.
• When an arbitration lost occurs, check if both MST and TRS bits are cleared to 0. If either or
both of MST and TRS bits are not cleared to 0, both the bits should be cleared to 0.

Section 17 A/D Converter (ADC)
This LSI includes a successive approximation type 12-bit A/D converter.
17.1 Features
• 12-bit resolution
• Input channels
Eight channels
• High-speed conversion
When Aφ = 40 MHz: Minimum 1.25 μs per channel
AD clock = 40 MHz, 50 conversion states
• Two operating modes
⎯ Single-cycle scan mode: Continuous A/D conversion on one to eight channels
⎯ Continuous scan mode: Repetitive A/D conversion on one to eight channels
• A/D data registers
Eight A/D data registers (ADDR) are provided. A/D conversion results are stored in A/D data
registers (ADDR) that correspond to the input channels.
• Sample-and-hold function
A sample-and-hold circuit is built into the A/D converter of this LSI, simplifying the
configuration of the external analog input circuitry. Multiple channels can be sampled
simultaneously because sample-and-hold circuits can be dedicated for channels 0 to 2 and 8 to
10.
⎯ Group A (GrA): Analog input pins selected from channels 0, 1, and 2 can be
simultaneously sampled.
• Three methods for starting conversion
Software: Setting of the ADST bit in ADCR
Timer: TRGAN, TRG0N, TRG4AN, and TRG4BN from the MTU2
TRGAN, TRG4AN, and TRG4BN from the MTU2S
External trigger: ADTRG (LSI pin)
• Selectable analog input channel
A/D conversion of a selected channel is accomplished by setting the A/D analog input channel
select registers (ADANSR).
• A/D conversion end interrupt and DMAC transfer function is supported
On completion of A/D conversion, A/D conversion end interrupts (ADI) can be generated and
the DMAC can be activated by ADI.

7 ADST 0 R/W A/D Start
When this bit is cleared to 0, A/D conversion is stopped
and the A/D converter enters the idle state. When this bit
is set to 1, A/D conversion is started. In single-cycle scan
mode, this bit is automatically cleared to 0 when A/D
conversion ends on the selected single channel. In
continuous scan mode, A/D conversion is continuously
performed for the selected channels in sequence until this
bit is cleared by software, a reset, or in software standby
mode, or module standby mode.
6 ADCS 0 R/W A/D Continuous Scan
Selects either a single-cycle or a continuous scan in scan
mode. This bit is valid only when scan mode is selected.
0: Single-cycle scan
1: Continuous scan
When changing the operating mode, first clear the ADST
bit to 0.
5 ACE 0 R/W Automatic Clear Enable
Enables or disables the automatic clearing of ADDR after
ADDR is read by the CPU or DMAC. When this bit is set
to 1, ADDR is automatically cleared to H'0000 after the
CPU or DMAC reads ADDR. This function allows the
detection of any renewal failures of ADDR.
0: Automatic clearing of ADDR after being read is
disabled.
1: Automatic clearing of ADDR after being read is enabled.

conversion start trigger.
When the external trigger is selected (EXTRG = 1), upon
input of a low-level pulse to the ADTRG pin after the
TRGE bit is set to 1, the A/D converter detects the falling
edge of the pulse, and sets the ADST bit in ADCR to 1.
The operation which is performed when 1 is written to the
ADST bit by software is subsequently performed. A/D
conversion start by the external trigger input is enabled
only when the ADST bit is cleared to 0.
When the external trigger is used as an A/D conversion
start trigger, the low-level pulse input to the ADTRG pin
must be at least 1.5 Aφ clock cycles in width.

17.4 Operation
The A/D converter has two operating modes: single-cycle scan mode and continuous scan mode.
In single-cycle scan mode, A/D conversion is performed once on one or more specified channels
and then it ends. In continuous scan mode, the A/D conversion is performed sequentially on one or
more specified channels until the ADST bit is cleared to 0.
The ADCS bit in the A/D control register (ADCR) is used to select the operating mode. Setting
the ADCS bit to 0 selects single-cycle scan mode and setting the ADCS bit to 1 selects continuous
scan mode. In both modes, A/D conversion starts on the channel with the lowest number in the
analog input channels selected by the A/D analog input channel select register (ADANSR) from
AN0 to AN7.
In single-cycle scan mode, when one cycle of A/D conversion on all specified channels is
completed, the ADF bit in ADSR is set to 1 and the ADST bit is automatically cleared to 0. In
continuous scan mode, when conversion on all specified channels is completed, the ADF bit in
ADSR is set to 1. To stop A/D conversion, write 0 to the ADST bit. When the ADF bit is set to 1,
if the ADIE bit in ADCR is set to 1, an A/D conversion end interrupt (ADI) is generated. When
clearing the ADF bit to 0, read the ADF bit while set to 1 and then write 0. However, when the
DMAC is activated by an ADI interrupt, the ADF bit is automatically cleared to 0.
17.4.1 Single-Cycle Scan Mode
The following example shows the operation when analog input channels 0 to 3 (AN0 to AN3) are
selected and the A/D conversion is performed in single-cycle scan mode using four channels.
1. Set the ADCS bit in the A/D control register (ADCR) to 0.
2. Set all bits ANS0 to ANS3 in the A/D analog input channel select register (ADANSR) to 1.
3. Set the ADST bit in the A/D control register (ADCR) to 1 to start A/D conversion.
4. After channels 0 to 2 (GrA) are sampled simultaneously, offset canceling processing (OFC) is
performed. Then, A/D conversion is performed on channel 0. Upon completion of the A/D
conversion, the A/D conversion result is transferred to ADDR0. Following this, channel 1 is
converted. Upon completion of the conversion, the A/D conversion result is transferred to
ADDR1. In the same way, channel 2 is converted and the A/D conversion result is transferred
to ADDR2.
A/D conversion of channel 3 is then started. Upon completion of the A/D conversion, the A/D
conversion result is transferred to ADDR3.

REJ09B0344-0300
5. When A/D conversion ends on all specified channels (AN0 to AN3), the ADF bit is set to 1,
the ADST bit is automatically cleared to 0, and the A/D conversion ends. At this time, if the
ADIE bit is set to 1, an ADI interrupt is generated after the A/D conversion.

17.4.2 Continuous Scan Mode
The following example shows the operation when analog input 0, 2, and 3 (AN0, AN2, AN3) are
selected and the A/D conversion is performed in continuous scan mode using the three channels.
This operation also applies to the A/D_1 conversion.
1. Set the ADCS bit in the A/D control register (ADCR) to 0.
2. Set all bits of ANS0, ANS2, and ANS3 in the A/D analog input channel select register
(ADANSR) to 1.
3. Set the ADST bit in the A/D control register (ADCR) to 1 to start A/D conversion.
4. Channels 0 and 2 (GrA) are sampled simultaneously. As the ANS1 bit in ADANSR is set to 0,
channel 1 is not sampled. After this, offset canceling processing (OFC) is performed. Then the
A/D conversion on channel 0 is started. Upon completion of the A/D conversion, the A/D
conversion result is transferred to ADDR0. In the same way, channel 2 is converted and the
A/D conversion result is transferred to ADDR2. The A/D conversion is not performed on
channel 1.
5. The A/D conversion of channel 3 starts. Upon completion of the A/D conversion, the A/D
conversion result is transferred to ADDR3.
6. When the A/D conversion ends on all the specified channels (AN0 to AN3), the ADF bit is set
to 1. At this time, if the ADIE bit is set to 1, an ADI interrupt is generated after the A/D
conversion.
7. Steps 4 to 6 are repeated as long as the ADST bit remains set to 1. When the ADST bit is
cleared to 0, the A/D conversion stops. After this, if the ADST bit is set to 1, the A/D
conversion starts again and repeats steps 4 to 6.

17.4.3 Input Sampling and A/D Conversion Time
The A/D converter has a built-in sample-and-hold circuit common to all the channels. Each of
channels 0 to 2 of the A/D converter has a dedicated built-in sample-and-hold circuit. Channels 0
to 2 can be simultaneously sampled as one group. This group is referred to as Group A (GrA) (in
table 17.5). Even when only one channel is selected in the group by ADANSR, the sample-and-
hold operation is performed with the dedicated sample-and-hold circuit. When only the channels
without a dedicated sample-and-hold circuit are specified by ADANSR, the time that elapses is the
same as when a dedicated sample-and-hold circuit is used.
When an event that sets the ADST bit, for example, writing to this bit by the CPU, A/D converter
activation request from the MTU2, the MTU2S, or an external trigger signal occurs, the analog
input is sampled by the dedicated sample-and-hold circuit for each channel after the A/D
conversion start delay time (tD) has passed and the offset canceling processing (OFC) is
performed. After this, the sampling of the analog input using the sample-and-hold circuit common
to all the channels is performed and then the A/D conversion is started. Figure 17.4 shows the A/D
conversion timing in this case. This A/D conversion time (tCONV) includes the tD, the offset
canceling processing time (tOFC), the analog input sampling time with a dedicated sample-and-hold
circuit for each channel (tSPLSH), and the analog input sampling time with the sample-and-hold
circuit common to all the channels (tSPL). The tSPLSH does not depend on the number of channels
simultaneously sampled.
In continuous scan mode, the A/D conversion time (tCONV) given in table 17.6 applies to the
conversion time of the first cycle. The conversion time of the second and subsequent cycles is
expressed as (tCONV − tD + 6).

17.4.4 A/D Converter Activation by MTU2 and MTU2S
A/D conversion is activated by the A/D conversion start triggers (TRGAN, TRG0N, TRG4N, and
TRG4BN) from the MTU2 and A/D conversion start triggers (TRGAN, TRG4AN, and TRG4BN)
from the MTU2S. To enable this function, set the TRGE bit in ADCR to 1 and clear the EXTRG
bit to 0. After this setting is made, if an A/D conversion start trigger from the MTU2 or MTU2S is
generated, the ADST bit is set to 1. The timing between the setting of the ADST bit and the start
of the A/D conversion is the same for all A/D conversion activation sources.
The A/D conversion start trigger must be input after ADCR, ADSTRGR, and ADANSR registers
have been set.

Rev. 3.00 Mar. 04, 2009 Page 788 of 1168
REJ09B0344-0300
17.4.5 External Trigger Input Timing
The A/D conversion can be externally triggered. To input an external trigger, set the pin function
controller (PFC) to select ADTRG pin function and drive the ADTRG pin low when a high level
is input to the ADTRG pin with the TRGE and EXTRG bits in ADCR are both set to 1. A falling
edge of the ADTRG pin sets the ADST bit in ADCR to 1, starting the A/D conversion. Other
operations are conducted in the same way for all A/D conversion activation sources. Figure 17.5
shows the timing.
The ADST bit is set to 1 after 5 states has elapsed from the point at which the A/D converter
detects a falling edge on the ADTRG pin. A low level input to the ADTRG pin must be made after
the ADCR, ADSTRGR, and ADANSR registers have been set.

17.4.6 Example of ADDR Auto-Clear Function
When the A/D data register (ADDR) is read by the CPU or DMAC, ADDR can be automatically
cleared to H'0000 by setting the ACE bit in ADCR to 1. This function allows the detection of non-
updated ADDR states.
Figure 17.6 shows an example of when the auto-clear function of ADDR is disabled (normal state)
and enabled.
Section 17 A/D Converter (ADC)
Rev. 3.00 Mar. 04, 2009 Page 789 of 1168
REJ09B0344-0300
When the ACE bit is 0 (initial value) and the A/D conversion result (H'0222) is not written to
ADDR for some reason, the old data (H'0111) becomes the ADDR value. In addition, when the
ADDR value is read into a general register using an A/D conversion end interrupt, the old data
(H'0111) is stored in the general register. To detect a renewal failure, every time the old data needs
to be stored in the RAM, a general register, etc.
When the ACE bit is 1, reading ADDR = H'0111 by the CPU or DMAC automatically clears
ADDR to H'0000. After this, if the A/D conversion result (H'0222) cannot be transferred to
ADDR for some reason, the cleared data (H'0000) remains as the ADDR value. When this ADDR
value is read into a general register, H'0000 is stored in the general register. Just by checking
whether the read data value is H'0000 or not allows the detection of non-updated ADDR states.

17.5 Interrupt Sources and DMAC Transfer Requests
The A/D converter generates A/D conversion end interrupts (ADI). An ADI interrupt generation is
enabled when the ADIE bit in ADCR is set to 1. The DMAC can be activated by the DMAC
setting when an ADI interrupt is generated. At this time, no interrupt to the CPU is generated.
When the DMAC is activated by an ADI interrupt, the ADF bit in ADSR is automatically cleared
at the data transfer by the DMAC.

17.6 Definitions of A/D Conversion Accuracy
This LSI's A/D conversion accuracy definitions are given below.
• Resolution
The number of A/D converter digital conversion output codes
• Offset error
The deviation of the actual A/D conversion characteristic from the ideal A/D conversion
characteristic when the digital output value changes from the minimum voltage value (zero
voltage) B'000000000000 to B'000000000001. Does not include a quantization error (see
figure 17.7).
• Full-scale error
The deviation of the actual A/D conversion characteristic from the ideal A/D conversion
characteristic when the digital output value changes from B'111111111110 to the maximum
voltage value (full-scale voltage) B'111111111111. Does not include a quantization error (see
figure 17.7).
• Quantization error
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 17.7).
• Nonlinearity error
The deviation of the actual A/D conversion characteristic from the ideal A/D conversion
characteristic between zero voltage and full-scale voltage. Does not include offset error, full-
scale error, or quantization error (see figure 17.7).
• Absolute accuracy
The deviation between the digital value and the analog input value. Includes offset error, full-
scale error, quantization error, and nonlinearity error.

17.7 Usage Notes
17.7.1 Relationship of AVcc and AVss to VccQ and VssQ
When using the A/D converter or D/A converter, make settings such that AVcc = 5.0 V ±0.5 V
and AVss = Vss. When the A/D converter and D/A converter are not used, make settings such that
AVcc = VccQ and AVss = VssQ, and do not leave the AVcc and AVss pins open.
17.7.2 AVREF Pin Setting Range
When using the A/D converter or D/A converter, set AVREF to a level between 4.5 V and AVcc.
When the A/D converter and D/A converter are not used, make settings such that AVREF =
AVcc, and do not leave the AVREF pin open.
The setting of the AVREFVss pin should always be such that AVREFVss = AVss, and do not
leave AVREFVss open. If these conditions are not met, the reliability of the SH7211 may be
adversely affected.
17.7.3 Notes on Board Design
In board design, digital circuitry and analog circuitry should be as mutually isolated as possible,
and the layout in which the digital circuit signal lines and analog circuit signal lines cross or are in
close proximity to each other should be avoided as much as possible. Failure to do so may result in
the incorrect operation of the analog circuitry due to inductance, adversely affecting the A/D
conversion values.
Also, digital circuitry must be isolated from the analog input signals (AN0 to AN7), analog
reference power supply (AVREF), the analog power supply (AVcc), the analog ground (AVss),
and the analog reference ground (AVREFVss). Also, AVss should be connected at one point to a
stable digital ground (Vss) on the board.

17.7.4 Notes on Noise Countermeasures
To prevent damage due to an abnormal voltage, such as an excessive surge at the analog input pins
(AN0 to AN7) and analog reference power supply (AVREF), a protection circuit should be
connected between the AVcc and AVss, as shown in figure 17.8. The AVREFVss and AVss
should be the same voltage. Also, the bypass capacitors connected to AVREF and the filter
capacitor connected to ANn should be connected to the AVss. If a filter capacitor is connected as
shown in figure 17.8, the input currents at the analog input pin (ANn) are averaged, and an error
may occur. Careful consideration is therefore required when deciding the circuit constants.

• Set the ADST bit in the A/D control register (ADCR) after the A/D start trigger select register
(ADSTRGR) and the A/D analog input channel select register (ADANSR) have been set. Do
not modify the settings of the ADCS, ACE, ADIE, TRGE, and EXTRG bits while the ADST
bit in the ADCR register is set to 1.
• Do not start the A/D conversion when the ANS bits (ANS[7:0]) in the A/D analog input
channel select register (ADANSR) are all 0.

18.4 Operation
The D/A converter includes D/A conversion circuits for two channels, each of which can operate
independently. When the DAOE bit in DACR is set to 1, D/A conversion is enabled and the
conversion result is output.
An operation example of D/A conversion on channel 0 is shown below. Figure 18.2 shows the
timing of this operation.
1. Write the conversion data to DADR0.
2. Set the DAOE0 bit in DACR to 1 to start D/A conversion. The conversion result is output from
the analog output pin DA0 after the conversion time tDCONV has elapsed. The conversion result
continues to be output until DADR0 is written to again or the DAOE0 bit is cleared to 0. The
output value is expressed by the following formula:
Contents of DADR
256 × AVref
3. If DADR0 is written to again, the conversion is immediately started. The conversion result is
output after the conversion time tDCONV has elapsed.
4. If the DAOE0 bit is cleared to 0, analog output is disabled.

18.5 Usage Notes
18.5.1 Module Standby Mode Setting
Operation of the D/A converter can be disabled or enabled using the standby control register. The
initial setting is for operation of the D/A converter to be halted. Register access is enabled by
canceling module standby mode. For details, see section 23, Power-Down Modes.
18.5.2 D/A Output Hold Function in Software Standby Mode
When this LSI enters software standby mode with D/A conversion enabled, the D/A outputs are
retained, and the analog power supply current is equal to as during D/A conversion. If the analog
power supply current needs to be reduced in software standby mode, clear the DAOE0, DAOE1,
and DAE bits to 0 to disable the D/A outputs.
18.5.3 Setting Analog Input Voltage
The reliability of this LSI may be adversely affected if the following voltage ranges are exceeded.
1. AVcc and AVss input voltages
Input voltages AVcc and AVss should be Vcc ≤ AVcc ≤ 5.0 V ± 0.5 V and AVss = Vss. Do
not leave the AVcc and AVss pins open when the A/D converter or D/A converter is not in use
and in software standby mode. When not in use, connect AVcc to the power supply (VccQ)
and AVss to the ground (VssQ).
2. Setting range of AVREF input voltage
Set the voltage range of the AVREF pin as AVREF = AVcc ± 0.3 V when the A/D converter
or D/A converter is used, or as AVREF = AVcc when no A/D converter or D/A converter is
used.

19.1.1 Port A I/O Registers H, L (PAIORH, PAIORL)
PAIORH and PAIORL are 16-bit readable/writable registers that are used to set the pins on port A
as inputs or outputs. Bits PA25IOR to PA0IOR correspond to pins PA25 to PA0. PAIORH and
PAIORL are enabled when the port A pins are functioning as general-purpose inputs/outputs
(PA25 to PA0) and for the TIOC input/output of the MTU2. In other states, they are disabled. A
given pin on port A will be an output pin if the corresponding bit in PAIORH or PAIORL is set to
1, and an input pin if the bit is cleared to 0.
Bits 15 to 10 of PAIORH are reserved. These bits are always read as 0. The write value should
always be 0.
PAIORH and PAIORL are initialized to H'0000 by a power-on reset; but are not initialized by a
manual reset or in sleep mode or software standby mode.

19.1.2 Port A Control Registers H1 to H3, L1 to L4 (PACRH1 to PACRH3, PACRL1 to
PACRL4)
PACRH1 to PACRH3 and PACRL1 to PACRL4 are 16-bit readable/writable registers that are
used to select the functions of the multiplexed pins on port A.
PACRH1 to PACRH3 and PACRL1 to PACRL4 are initialized to the values shown in table 19.5
by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby
mode.

19.1.3 Port B I/O Registers H, L (PBIORH, PBIORL)
PBIORH and PBIORL are 16-bit readable/writable registers that are used to set the pins on port B
as inputs or outputs. Bits PB30IOR to PB0IOR correspond to pins PB30 to PB0, respectively.
PBIOR is enabled when the port B pins are functioning as general-purpose inputs/outputs (PB9,
PB5, and PB4). In other states, PBIOR is disabled. A given pin on port B will be an output pin if
the corresponding bit in PBIORH and PBIORL is set to 1, and an input pin if the bit is cleared to
0.
Bit 15 of PBIORH is reserved. This bit is always read as 0. The write value should always be 0.
PBIORH and PBIORL are initialized to H'0000 by a power-on reset; but are not initialized by a
manual reset or in sleep mode or software standby mode.

19.1.4 Port B Control Registers H1 to H4, L1 to L4 (PBCRH1 to PBCRH4, PBCRL1 to
PBCRL4)
PBCRH1 to PBCRH4 and PBCRL1 to PBCRL4 are 16-bit readable/writable registers that are
used to select the function of the multiplexed pins on port B.
PBCRH1 to PBCRH4 and PBCRL1 to PBCRL4 are initialized to the values shown in table 19.5
by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby
mode.

19.1.5 Port D I/O Register (PDIOR)
PDIOR is a 16-bit readable/writable register that is used to set the pins on port D as inputs or
outputs. Bits PD15IOR to PD0IOR correspond to pins PD15 to PD0. PDIOR is enabled when the
port D pins are functioning as general-purpose inputs/outputs (PD15 to PD0). In other states,
PDIOR is disabled. A given pin on port D will be an output pin if the corresponding bit in PDIOR
is set to 1, and an input pin if the bit is cleared to 0.
PDIOR is initialized to H'0000 by a power-on; but is not initialized by a manual reset or in sleep
mode or software standby mode.

Section 20 I/O Ports
This LSI has four ports: A, B, D, and F.
All port pins are multiplexed with other pin functions. The functions of the multiplex pins are
selected by means of the pin function controller (PFC).
Each port is provided with data registers for storing the pin data and port registers for reading the
states of the pins.
20.1 Port A
Port A is an input/output port with the 26 pins shown in figure 20.1.

20.1.2 Port A Data Registers H, L (PADRH, PADRL)
PADRH and PADRL are 16-bit readable/writable registers that store port A data. Bits PA25DR to
PA0DR correspond to pins PA25 to PA0, respectively.
When a pin function is general output, if a value is written to PADRH or PADRL, the value is
output directly from the pin, and if PADRH or PADRL is read, the register value is returned
directly regardless of the pin state.
When a pin function is general input, if PADRH or PADRL is read, the pin state, not the register
value, is returned directly. If a value is written to PADRH or PADRL, although that value is
written into PADRH or PADRL, it does not affect the pin state. Table 20.2 summarizes PADRH
and PADRL read/write operations.
PADRH and PADRL are initialized to the respective values shown in table 20.1 by a power-on
reset. PADRH and PADRL are not initialized by a manual reset or in sleep mode or software
standby mode.

20.3.2 Port D Data Register L (PDDRL)
PDDRL is a 16-bit readable/writable register that stores port D data. Bits PD15DR to PD0DR
correspond to pins PD15 to PD0, respectively.
When a pin function is general output, if a value is written to PDDRL, the value is output directly
from the pin, and if PDDRL is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PDDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PDDRL, although that value is written into PDDRL, it
does not affect the pin state. Table 20.8 summarizes PDDRL read/write operations.
PDDRL is initialized to the respective values shown in table 20.5 by a power-on reset, but is not
initialized by a manual reset or in sleep mode or software standby mode.

Section 21 Flash Memory
This LSI has 384/512*-kbyte on-chip flash memory. The flash memory has the following features.
21.1 Features
• Two flash-memory MATs, with one selected by the mode in which the LSI starts up
The on-chip flash memory has two memory spaces in the same address space (hereafter
referred to as memory MATs). The mode setting when the LSI starts up determines the
memory MAT that is currently mapped. The MAT can be switched by bank-switching after the
LSI has started up.
⎯ Size of the user MAT, from which booting-up proceeds after a power-on reset in user
mode: 384/512 kbytes*
⎯ Size of the user boot MAT, from which booting-up proceeds after a power-on reset in user
boot mode: 12 kbytes
• Three on-board programming modes and one off-board programming mode
On-board programming modes
Boot Mode: The on-chip SCIF interface is used for programming in this mode. Either the user
MAT or user-boot MAT can be programmed, and the bit rate for data transfer between the host
and this LSI are automatically adjusted.
User Program Mode: This mode allows programming of the user MAT via any desired
interface.
User Boot Mode: This mode allows writing of a user boot program via any desired interface
and programming of the user MAT.
Off-board programming mode
Programmer Mode: This mode allows programming of the user MAT and user boot MAT
with the aid of a PROM programmer.
• Downloading of an on-chip program to provide an interface for programming/erasure
This LSI has a dedicated programming/erasing program. After this program has been
downloaded to the on-chip RAM, programming or erasing can be performed by setting
parameters as arguments. “User branching” is also supported.
Note: * See Appendix B. Product Lineup.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 886 of 1168
REJ09B0344-0300
⎯ User branching
Programming is performed in 256-byte units. Each round of programming consists of
application of the programming pulse, reading for verification, and several other steps. Erasing
is performed in block units and each round of erasing consists of several steps. A user-
processing routine can be executed between each round of erasing, and making the setting for
this is called the addition of a user branch.
• Protection modes
There are two modes of protection: software protection is applied by register settings and
hardware protection is applied by the level on the FWE pin. Protection of the flash memory
from programming or erasure can be selected.
When an abnormal state is detected, such as runaway execution of programming/erasing, the
protection modes initiate the transition to the error protection state and suspend
programming/erasing processing.
• Programming/erasing time
The time taken to program 256 bytes of flash memory in a single round is 2 ms (typ.), which is
equivalent to 7.8 μs per byte. The erasing time is 80 ms (typ.) per 8-Kbyte block, 600 ms (typ.)
per 64-Kbyte block, and 1200 ms (typ.) per 128-Kbyte block.
• Number of programming operations
The flash memory can be programmed up to 100 times.
• Operating frequency for programming/erasing
The operating frequency range for programming/erasing Iφ = 32 to 40 MHz

21.2.4 Flash Memory Configuration
This LSI's flash memory is configured by the 384/512-kbyte* user MAT and 12-kbyte user boot
MAT.
The start address is allocated to the same address in the user MAT and user boot MAT. Therefore,
when the program execution or data access is performed between the two MATs, the MAT must
be switched by using FMATS.
The user MAT or user boot MAT can be read in all modes if it is in ROM valid mode. However,
the user boot MAT can be programmed only in boot mode and programmer mode.

The user MAT and user boot MAT have different memory sizes. Do not access a user boot MAT
that is 12 kbytes or more. When a user boot MAT exceeding 12 kbytes is read from, an undefined
value is read.

21.2.6 Programming/Erasing Interface
Programming/erasing is executed by downloading the on-chip program to the on-chip RAM and
specifying the program address/data and erase block by using the interface registers/parameters.
The procedure program is made by the user in user program mode and user boot mode. The
overview of the procedure is as follows. For details, see section 21.5.2, User Program Mode.

(1) Selection of On-Chip Program to be Downloaded and Setting of Download Destination
This LSI has programming/erasing programs and they can be downloaded to the on-chip
RAM. The on-chip program to be downloaded is selected by setting the corresponding bits in
the programming/erasing interface registers. The download destination can be specified by
FTDAR.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 894 of 1168
REJ09B0344-0300
(2) Download of On-Chip Program
The on-chip program is automatically downloaded by clearing VBR of the CPU to
H'80000000 and then setting the SCO bit in the flash code control and status register (FCCS)
and the flash key code register (FKEY), which are programming/erasing interface registers.
The user MAT is replaced to the embedded program storage area when downloading. Since the
flash memory cannot be read when programming/erasing, the procedure program, which is
working from download to completion of programming/erasing, must be executed in a space
other than the flash memory to be programmed/erased (for example, on-chip RAM).
Since the result of download is returned to the programming/erasing interface parameters,
whether the normal download is executed or not can be confirmed.
Note that VBR can be changed after download is completed.
(3) Initialization of Programming/Erasing
The operating frequency and user branch are set before execution of programming/erasing.
The user branch destination must be in an area other than the user MAT area which is in the
middle of programming and the area where the on-chip program is downloaded. These settings
are performed by using the programming/erasing interface parameters.
(4) Programming/Erasing Execution
To program or erase, the FWE pin must be brought high and user program mode must be
entered.
The program data/programming destination address is specified in 256-byte units when
programming.
The block to be erased is specified in erase-block units when erasing.
These specifications are set by using the programming/erasing interface parameters and the on-
chip program is initiated. The on-chip program is executed by using the JSR or BSR
instruction to perform the subroutine call of the specified address in the on-chip RAM. The
execution result is returned to the programming/erasing interface parameters.
The area to be programmed must be erased in advance when programming flash memory.
Ensure that NMI, IRQ, and all other interrupts are not generated during programming or
erasing.
(5) When Programming/Erasing is Executed Consecutively
When the processing is not ended by the 256-byte programming or one-block erasure, the
program address/data and erase-block number must be updated and consecutive
programming/erasing is required.
Since the downloaded on-chip program is left in the on-chip RAM after the processing,
download and initialization are not required when the same processing is executed
consecutively.

Value R/W Description
0 SCO 0 (R)/W Source Program Copy Operation
Requests the on-chip programming/erasing program to be
downloaded to the on-chip RAM.
When this bit is set to 1, the on-chip program which is
selected by FPCS/FECS is automatically downloaded in
the on-chip RAM area specified by FTDAR.
In order to set this bit to 1, H'A5 must be written to FKEY
and this operation must be in the on-chip RAM.
Thirty-two NOP instructions must be executed
immediately after setting this bit to 1.
For interrupts during download, see section 21.7.2,
Interrupts during Programming/Erasing. For the download
time, see section 21.7.3, Other Notes.
Since this bit is cleared to 0 when download is completed,
this bit cannot be read as 1.
Download by setting the SCO bit to 1 requires a special
interrupt processing that performs bank switching to the
on-chip program storage area. Therefore, before issuing a
download request (SCO = 1), set VBR to H'80000000.
Otherwise, the CPU gets out of control. Once download
end is confirmed, VBR can be changed to any other value.
The mode in which the FWE pin is high must be used
when using the SCO function.
0: Download of the on-chip programming/erasing program
to the on-chip RAM is not executed.
[Clearing condition]
When download is completed
1: Request that the on-chip programming/erasing program
is downloaded to the on-chip RAM is generated
[Setting conditions]
When all of the following conditions are satisfied and 1 is
written to this bit
• FKEY is written to H'A5
• During execution in the on-chip RAM

When a value other than H'A5 is written to FKEY, 1
cannot be written to the SCO bit. Therefore downloading
to the on-chip RAM cannot be executed.
Only when H'5A is written, programming/erasing of flash
memory can be executed. Even if the on-chip
programming/erasing program is executed, flash memory
cannot be programmed or erased when a value other than
H'5A is written to FKEY.

on-chip RAM instruction.
When the MAT is switched, follow section 21.7.1,
Switching between User MAT and User Boot MAT. (The
user boot MAT cannot be programmed in user program
mode if user boot MAT is selected by FMATS. The user
boot MAT must be programmed in boot mode or in
programmer mode.)

7 TDER 0 R/W Transfer Destination Address Setting Error
This bit is set to 1 when there is an error in the download start
address set by bits 6 to 0 (TDA6 to TDA0). Whether the address
setting is erroneous or not is tested by checking whether the
setting of TDA6 to TDA0 is in the range of H'00 to H'05 after
setting the SCO bit in FCCS to 1 and performing download.
Before setting the SCO bit to 1 be sure to set the FTDAR value
between H'00 to H'05 as well as clearing this bit to 0.
0: Setting of TDA6 to TDA0 is normal
1: Setting of TDER and TDA6 to TDA0 is H'06 to H'FF and
download has been aborted
6 to 0 TDA[6:0] All 0 R/W Transfer Destination Address
These bits specify the download start address. A value from
H'00 to H'05 can be set to specify the download start address in
on-chip RAM in 2-kbyte units.
A value from H'06 to H'7F cannot be set. If such a value is set,
the TDER bit (bit 7) in this register is set to 1 to prevent
download from being executed.
H'00: Download start address is set to H'FFF81000
H'01: Download start address is set to H'FFF81800

21.4.3 Programming/Erasing Interface Parameters
The programming/erasing interface parameters specify the operating frequency, user branch
destination address, storage place for program data, programming destination address, and erase
block and exchanges the processing result for the downloaded on-chip program. This parameter
uses the general registers of the CPU (R4, R5, and R0) or the on-chip RAM area. The initial value
is undefined.
At download all CPU registers are stored, and at initialization or when the on-chip program is
executed, CPU registers except for R0 are stored. The return value of the processing result is
written in R0. Since the stack area is used for storing the registers or as a work area, the stack area
must be saved at the processing start. (The maximum size of a stack area to be used is 128 bytes.)
The programming/erasing interface parameters are used in the following four items.
1. Download control
2. Initialization before programming or erasing
3. Programming
4. Erasing
These items use different parameters. The correspondence table is shown in table 21.6.
The processing results of initialization, programming, and erasing are returned, but the bit contents
have different meanings according to the processing program. See the description of FPFR for
each processing.

(1) Download Control
The on-chip program is automatically downloaded by setting the SCO bit to 1. The on-chip RAM
area to be downloaded is the area as much as 3 kbytes starting from the start address specified by
FTDAR. For the address map of the on-chip RAM, see figure 21.10.
The download control is set by using the programming/erasing interface registers. The return
value is given by the DPFR parameter.
(a) Download Pass/Fail Result Parameter (DPFR: One Byte of Start Address of On-Chip
RAM Specified by FTDAR)
This parameter indicates the return value of the download result. The value of this parameter can
be used to determine if downloading is executed or not. Since the confirmation whether the SCO
bit is set to 1 is difficult, the certain determination must be performed by setting one byte of the
start address of the on-chip RAM area specified by FTDAR to a value other than the return value
of download (for example, H'FF) before the download start (before setting the SCO bit to 1). For

Undefined R/W User Branch Destination Address
When the user branch is not required, address 0
(H'00000000) must be set.
The user branch destination must be an area other than
the flash memory, an area other than the RAM area in
which on-chip program has been transferred, or the
external bus space.
Note that the CPU must not branch to an area without
the execution code and get out of control. The on-chip
program download area and stack area must not be
overwritten. If CPU runaway occurs or the download
area or stack area is overwritten, the value of flash
memory cannot be guaranteed.
The download of the on-chip program, initialization,
initiation of the programming/erasing program must not
be executed in the processing of the user branch
destination. Programming or erasing cannot be
guaranteed when returning from the user branch
destination. The program data which has already been
prepared must not be programmed.
Store general registers R8 to R15. General registers R0
to R7 are available without storing them.
Moreover, the programming/erasing interface registers
must not be written to in the processing of the user
branch destination.
After the processing of the user branch has ended, the
programming/erasing program must be returned to by
using the RTS instruction.
For the execution intervals of the user branch
processing, see note 2 (User branch processing
intervals) in section 21.7.3, Other Notes.

(3) Programming Execution
When flash memory is programmed, the programming destination address and programming data
on the user MAT must be passed to the programming program in which the program data is
downloaded.
1. The start address of the programming destination on the user MAT is set in general register R5
of the CPU. This parameter is called FMPAR (flash multipurpose address area parameter).
Since the program data is always in 256-byte units, the lower eight bits (MOA7 to MOA0)
must be H'00 as the boundary of the programming start address on the user MAT.
2. The program data for the user MAT must be prepared in the consecutive area. The program
data must be in the consecutive space which can be accessed by using the MOV.B instruction
of the CPU and is not the flash memory space.
When data to be programmed does not satisfy 256 bytes, the 256-byte program data must be
prepared by embedding the dummy code (H'FF).
The start address of the area in which the prepared program data is stored must be set in
general register R4. This parameter is called FMPDR (flash multipurpose data destination area

21.5 On-Board Programming Mode
When the pin is set in on-board programming mode and the reset start is executed, the on-board
programming state that can program/erase the on-chip flash memory is entered. On-board
programming mode has three operating modes: user program mode, user boot mode, and boot
mode.
For details on the pin setting for entering each mode, see table 21.1. For details on the state
transition of each mode for flash memory, see figure 21.2.
21.5.1 Boot Mode
Boot mode executes programming/erasing user MAT and user boot MAT by means of the control
command and program data transmitted from the host using the on-chip SCI. The tool for
transmitting the control command and program data must be prepared in the host. The SCI
communication mode is set to asynchronous mode. When reset start is executed after this LSI's pin
is set in boot mode, the boot program in the microcontroller is initiated. After the SCI bit rate is
automatically adjusted, the communication with the host is executed by means of the control
command method.
The system configuration diagram in boot mode is shown in figure 21.6. For details on the pin
setting in boot mode, see table 21.1. Interrupts are ignored in boot mode, so do not generate them.
Note that the AUD cannot be used during boot mode operation.

(1) SCIF Interface Setting by Host
When boot mode is initiated, this LSI measures the low period of asynchronous SCIF-
communication data (H'00), which is transmitted consecutively by the host. The SCIF
transmit/receive format is set to 8-bit data, 1 stop bit, and no parity. This LSI calculates the bit rate
of transmission by the host by means of the measured low period and transmits the bit adjustment
end sign (1 byte of H'00) to the host. The host must confirm that this bit adjustment end sign
(H'00) has been received normally and transmits 1 byte of H'55 to this LSI. When reception is not
executed normally, boot mode is initiated again (reset) and the operation described above must be
executed. The bit rate between the host and this LSI is not matched because of the bit rate of
transmission by the host and system clock frequency of this LSI. To operate the SCIF normally,
the transfer bit rate of the host must be set to 9,600 bps or 19,200 bps.
The system clock frequency which can automatically adjust the transfer bit rate of the host and the
bit rate of this LSI is shown in table 21.7. Boot mode must be initiated in the range of this system
clock.

(2) State Transition Diagram
Figure 21.8 gives an overview of the state transitions after the chip has been started up in boot
mode. For details on boot mode, see section 21.8.1, Specifications of the Standard Serial
Communications Interface in Boot Mode.
1. Bit-rate matching
After the chip has been started up in boot mode, bit-rate matching between the SCI and the
host proceeds.
2. Waiting for inquiry and selection commands
The chip sends the requested information to the host in response to inquiries regarding the size
and configuration of the user MAT, start addresses of the MATs, information on supported
devices, etc.
3. Automatic erasure of the entire user MAT and user boot MAT
After all necessary inquiries and selections have been made and the command for transition to
the programming/erasure state is sent by the host, the entire user MAT and user boot MAT are
automatically erased.
4. Waiting for programming/erasure command
⎯ On receiving the programming selection command, the chip waits for data to be
programmed. To program data, the host transmits the programming command code
followed by the address where programming should start and the data to be programmed.
This is repeated as required while the chip is in the programming-selected state. To
terminate programming, H'FFFFFFFF should be transmitted as the first address of the area
for programming. This makes the chip return to the programming/erasure command
waiting state from the programming data waiting state.
⎯ On receiving the erasure select command, the chip waits for the block number of a block to
be erased. To erase a block, the host transmits the erasure command code followed by the
number of the block to be erased. This is repeated as required while the chip is in the
erasure-selected state. To terminate erasure, H'FF should be transmitted as the block
number. This makes the chip return to the programming/erasure command waiting state
from the erasure block number waiting state. Erasure should only be executed when a
specific block is to be reprogrammed without executing a reset-start of the chip after the
flash memory has been programmed in boot mode. If all desired programming is done in a
single operation, such erasure processing is not necessary because all blocks are erased
before the chip enters the programming/erasure/other command waiting state.
⎯ In addition to the programming and erasure commands, commands for sum checking and
blank checking (checking for erasure) of the user MAT and user boot MAT, reading data
from the user MAT/user boot MAT, and acquiring current state information are provided.

21.5.2 User Program Mode
The user MAT can be programmed/erased in user program mode. (The user boot MAT cannot be
programmed/erased.)
Programming/erasing is executed by downloading the program in the microcontroller.
The overview flow is shown in figure 21.9.
High voltage is applied to internal flash memory during the programming/erasing processing.
Therefore, transition to reset must not be executed. Doing so may cause damage or destroy flash
memory. If reset is executed accidentally, the reset signal must be released after the reset input
period, which is longer than the normal 100 μs.
For details on the programming procedure, see the description in section 21.5.2 (2), Programming
Procedure in User Program Mode. For details on the erasing procedure, see the description in
section 21.5.2 (3), Erasing Procedure in User Program Mode.
For the overview of a processing that repeats erasing and programming by downloading the
programming program and the erasing program in separate on-chip ROM areas using FTDAR, see
the description in section 21.5.2 (4), Erasing and Programming Procedure in User Program Mode.

Figure 21.11 Programming Procedure
The details of the programming procedure are described below. The procedure program must be
executed in an area other than the flash memory to be programmed. Especially the part where the
SCO bit in FCCS is set to 1 for downloading must be executed in the on-chip RAM. Specify 4:4:4
as the frequency division ratios of an internal clock (Iφ), a bus clock (Bφ), and a peripheral clock
(Pφ) through the frequency control register (FRQCR).
The area that can be executed in the steps of the user procedure program (on-chip RAM, user
MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program
and Data for Programming.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 927 of 1168
REJ09B0344-0300
The following description assumes the area to be programmed on the user MAT is erased and
program data is prepared in the consecutive area. When erasing has not been executed, carry out
erasing before writing.
256-byte programming is performed in one program processing. When more than 256-byte
programming is performed, programming destination address/program data parameter is updated
in 256-byte units and programming is repeated.
When less than 256-byte programming is performed, data must total 256 bytes by adding the
invalid data. If the invalid data to be added is H'FF, the program processing period can be
shortened.
(2.1) Select the on-chip program to be downloaded
When the PPVS bit of FPCS is set to 1, the programming program is selected.
Several programming/erasing programs cannot be selected at one time. If several programs are
set, download is not performed and a download error is returned to the source select error
detect (SS) bit in the DPFR parameter.
Specify the start address of the download destination by FTDAR.
(2.2) Write H'A5 in FKEY
If H'A5 is not written to FKEY for protection, 1 cannot be written to the SCO bit for a
download request.
(2.3) VBR is set to 0 and 1 is written to the SCO bit of FCCS, and then download is executed.
VBR must always be set to H'80000000 before setting the SCO bit to 1.
To write 1 to the SCO bit, the following conditions must be satisfied.
• H'A5 is written to FKEY.
• The SCO bit writing is executed in the on-chip RAM.
When the SCO bit is set to 1, download is started automatically. When execution returns to the
user procedure program, the SCO bit is cleared to 0. Therefore, the SCO bit cannot be
confirmed to be 1 in the user procedure program.
The download result can be confirmed only by the return value of the DPFR parameter. Before
the SCO bit is set to 1, incorrect decision must be prevented by setting the DPFR parameter,
that is one byte of the start address of the on-chip RAM area specified by FTDAR, to a value
other than the return value (H'FF).
When download is executed, particular interrupt processing, which is accompanied by the bank
switch as described below, is performed as an internal microcontroller processing, so VBR
need to be set to H'80000000. Thirty-two NOP instructions are executed immediately after the
instructions that set the SCO bit to 1.

1. The user MAT space is switched to the on-chip program storage area.
2. After the selection condition of the download program and the address set in FTDAR are
checked, the transfer processing is executed starting to the on-chip RAM address specified
by FTDAR.
3. The SCO bits in FCCS, FPCS, and FECS are cleared to 0.
4. The return value is set to the DPFR parameter.
5. After the on-chip program storage area is returned to the user MAT space, execution
returns to the user procedure program.
After download is completed and the user procedure program is running, the VBR setting can
be changed.
The notes on download are as follows.
In the download processing, the values of the general registers of the CPU are retained.
During the download processing, interrupts must not be generated. For details on the
relationship between download and interrupts, see section 21.7.2, Interrupts during
Programming/Erasing.
Since a stack area of maximum 256 bytes is used, an area of at least 128 bytes must be saved
before setting the SCO bit to 1.
If flash memory is accessed by the DMAC during downloading, operation cannot be
guaranteed. Therefore, access by the DMAC must not be executed.
(2.4) FKEY is cleared to H'00 for protection.
(2.5) The value of the DPFR parameter must be checked to confirm the download result.
A recommended procedure for confirming the download result is shown below.
1. Check the value of the DPFR parameter (one byte of start address of the download
destination specified by FTDAR). If the value is H'00, download has been performed
normally. If the value is not H'00, the source that caused download to fail can be
investigated by the description below.
2. If the value of the DPFR parameter is the same as before downloading (e.g. H'FF), the
address setting of the download destination in FTDAR may be abnormal. In this case,
confirm the setting of the TDER bit (bit 7) in FTDAR.
3. If the value of the DPFR parameter is different from before downloading, check the SS bit
(bit 2) and the FK bit (bit 1) in the DPFR parameter to ensure that the download program
selection and FKEY register setting were normal, respectively.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 929 of 1168
REJ09B0344-0300
(2.6) The operating frequency is set to the FPEFEQ parameter and the user branch destination is
set to the FUBRA parameter for initialization.
1. The current frequency of the CPU clock is set to the FPEFEQ parameter (general register
R4). The settable range Iφ of the FPEFEQ parameter is 32 to 40 MHz.
When the frequency is set out of this range, an error is returned to the FPFR parameter of
the initialization program and initialization is not performed. For details on the frequency
setting, see the description in section 21.4.3 (2.1), Flash Programming/Erasing Frequency
Parameter (FPEFEQ: General Register R4 of CPU).
2. The start address in the user branch destination is set to the (FUBRA: CPU general register
R5) parameter.
When the user branch processing is not required, 0 must be set to FUBRA.
When the user branch is executed, the branch destination is executed in flash memory other
than the one that is to be programmed. The area of the on-chip program that is downloaded
cannot be set.
The program processing must be returned from the user branch processing by the RTS
instruction.
See the description in section 21.4.3 (2.2), Flash User Branch Address Setting Parameter
(FUBRA: General Register R5 of CPU).
(2.7) Initialization
When a programming program is downloaded, the initialization program is also downloaded to
on-chip RAM. There is an entry point of the initialization program in the area from (download
start address set by FTDAR) + 32 bytes. The subroutine is called and initialization is executed
by using the following steps.
MOV.L #DLTOP+32,R1 ; Set entry address to R1
JSR @R1 ; Call initialization routine
NOP
1. The general registers other than R0 are saved in the initialization program.
2. R0 is a return value of the FPFR parameter.
3. Since the stack area is used in the initialization program, a stack area of 256 bytes or more
must be reserved in RAM.
4. Interrupts can be accepted during the execution of the initialization program. However, the
program storage area and stack area in on-chip RAM and register values must not be
destroyed.

(2.8) The return value of the initialization program, FPFR (general register R0) is checked.
(2.9) FKEY must be set to H'5A and the user MAT must be prepared for programming.
(2.10) The parameter which is required for programming is set.
The start address of the programming destination of the user MAT (FMPAR) is set to general
register R5. The start address of the program data storage area (FMPDR) is set to general
register R4.
1. FMPAR setting
FMPAR specifies the programming destination start address. When an address other than
one in the user MAT area is specified, even if the programming program is executed,
programming is not executed and an error is returned to the return value parameter FPFR.
Since the unit is 256 bytes, the lower eight bits (MOA7 to MOA0) must be in the 256-byte
boundary of H'00.
2. FMPDR setting
If the storage destination of the program data is flash memory, even when the program
execution routine is executed, programming is not executed and an error is returned to the
FPFR parameter. In this case, the program data must be transferred to on-chip RAM and
then programming must be executed.
(2.11) Programming
There is an entry point of the programming program in the area from (download start address
set by FTDAR) + 16 bytes of on-chip RAM. The subroutine is called and programming is
executed by using the following steps.
MOV.L #DLTOP+16,R1 ; Set entry address to R1
JSR @R1 ; Call programming routine
NOP
1. The general registers other than R0 are saved in the programming program.
2. R0 is a return value of the FPFR parameter.
3. Since the stack area is used in the programming program, a stack area of maximum 128
bytes must be reserved in RAM.
Section 21 Flash Memory

REJ09B0344-0300
(2.12) The return value in the programming program, FPFR (general register R0) is checked.
(2.13) Determine whether programming of the necessary data has finished.
If more than 256 bytes of data are to be programmed, specify FMPAR and FMPDR in 256-
byte units, and repeat steps (2.10) to (2.13). Increment the programming destination address by
256 bytes and update the programming data pointer correctly. If an address which has already
been programmed is written to again, not only will a programming error occur, but also flash
memory will be damaged.
(2.14) After programming finishes, clear FKEY and specify software protection.
If this LSI is restarted by a power-on reset immediately after user MAT programming has
finished, secure a reset period (period of RES = 0) that is at least as long as the normal 100 μs.

Figure 21.12 Erasing Procedure
The details of the erasing procedure are described below. The procedure program must be
executed in an area other than the user MAT to be erased.
Especially the part where the SCO bit in FCCS is set to 1 for downloading must be executed in on-
chip RAM.
The area that can be executed in the steps of the user procedure program (on-chip RAM, user
MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program
and Data for Programming.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 933 of 1168
REJ09B0344-0300
The frequency division ratio of an internal clock (Iφ), a bus clock (Bφ), and a peripheral clock (Pφ)
is specified as 4:4:4 by the frequency control register (FRQCR).
For the downloaded on-chip program area, see the RAM map for programming/erasing in figure
21.10.
A single divided block is erased by one erasing processing. For block divisions, see figure 21.4.
To erase two or more blocks, update the erase block number and perform the erasing processing
for each block.
(3.1) Select the on-chip program to be downloaded and the download destination address
Set the EPVB bit in FECS to 1.
Several programming/erasing programs cannot be selected at one time. If several programs are
set, download is not performed and a download error is returned to the source select error
detect (SS) bit in the DPFR parameter.
Specify the start address of the download destination by FTDAR.
The procedures to be carried out after setting FKEY, e.g. download and initialization, are the
same as those in the programming procedure. For details, see the description in section 21.5.2
(2), Programming Procedure in User Program Mode.
(3.2) Set the FEBS parameter necessary for erasure
Set the erase block number of the user MAT in the flash erase block select parameter (FEBS:
general register R4). If a value other than an erase block number of the user MAT is set, no
block is erased even though the erasing program is executed, and an error is returned to the
return value parameter FPFR.
(3.3) Erasure
Similar to as in programming, there is an entry point of the erasing program in the area from
(download start address set by FTDAR) + 16 bytes of on-chip RAM. The subroutine is called
and erasing is executed by using the following steps.
MOV.L #DLTOP+16,R1 ; Set entry address to R1
JSR @R1 ; Call erasing routine
NOP
1. The general registers other than R0 are saved in the erasing program.
2. R0 is a return value of the FPFR parameter.
3. Since the stack area is used in the erasing program, a stack area of maximum 128 bytes
must be reserved in RAM.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 934 of 1168
REJ09B0344-0300
(3.4) The return value in the erasing program, FPFR (general register R0) is checked.
(3.5) Determine whether erasure of the necessary blocks has finished.
If more than one block is to be erased, update the FEBS parameter and repeat steps (3.2) to
(3.5). Blocks that have already been erased can be erased again.
(3.6) After erasure finishes, clear FKEY and specify software protection.
If this LSI is restarted by a power-on reset immediately after user MAT erasing has finished,
secure a reset period (period of RES = 0) that is at least as long as the normal 100 μs.
(4) Erasing and Programming Procedure in User Program Mode
By changing the on-chip RAM address of the download destination in FTDAR, the erasing
program and programming program can be downloaded to separate on-chip RAM areas.
Figure 21.13 shows an example of repetitively executing RAM emulation, erasing, and
programming.

REJ09B0344-0300
Download and initialization are performed only once at the beginning.
In this kind of operation, note the following:
1. Be careful not to destroy on-chip RAM with overlapped settings.
In addition to the erasing program area and programming program area, areas for the user
procedure programs, work area, and stack area are reserved in on-chip RAM. Do not make
settings that will overwrite data in these areas.
2. Be sure to initialize both the erasing program and programming program.
Initialization by setting the FPEFEQ and FUBRA parameters must be performed for both
the erasing program and the programming program. Initialization must be executed for
both entry addresses: (download start address for erasing program) + 32 bytes
(H'FFF81020 in this example) and (download start address for programming program) + 32
bytes (H'FFF82020 in this example).
21.5.3 User Boot Mode
This LSI has user boot mode which is initiated with different mode pin settings than those in user
program mode or boot mode. User boot mode is a user-arbitrary boot mode, unlike boot mode that
uses the on-chip SCIF.
Only the user MAT can be programmed/erased in user boot mode. Programming/erasing of the
user boot MAT is only enabled in boot mode or programmer mode.
(1) User Boot Mode Initiation
For the mode pin settings to start up user boot mode, see table 21.1.
When the reset start is executed in user boot mode, the check routine for flash-memory related
registers runs on the on-chip RAM. NMI and all other interrupts cannot be accepted. Neither can
the AUD be used in this period. This period is 100 μs while operating at an internal frequency of
40 MHz.
Next, processing starts from the execution start address of the reset vector in the user boot MAT.
At this point, H'AA is set to the flash MAT select register (FMATS) because the execution MAT
is the user boot MAT.

REJ09B0344-0300
(2) User MAT Programming in User Boot Mode
For programming the user MAT in user boot mode, additional processings made by setting
FMATS are required: switching from user-boot-MAT selection state to user-MAT selection
state, and switching back to user-boot-MAT selection state after programming completes.
Figure 21.14 shows the procedure for programming the user MAT in user boot mode.

REJ09B0344-0300
The difference between the programming procedures in user program mode and user boot
mode is whether the MAT is switched or not as shown in figure 21.14.
In user boot mode, the user boot MAT can be seen in the flash memory space with the user
MAT hidden in the background. The user MAT and user boot MAT are switched only while
the user MAT is being programmed. Because the user boot MAT is hidden while the user
MAT is being programmed, the procedure program must be located in an area other than flash
memory. After programming finishes, switch the MATs again to return to the first state.
MAT switchover is enabled by writing a specific value to FMATS. However note that while
the MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not
allowed until MAT switching is completely finished, and if an interrupt occurs, from which
MAT the interrupt vector is read from is undetermined. Perform MAT switching in accordance
with the description in section 21.7.1, Switching between User MAT and User Boot MAT.
Except for MAT switching, the programming procedure is the same as that in user program
mode.
The area that can be executed in the steps of the user procedure program (on-chip RAM, user
MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural
Program and Data for Programming.

For erasing the user MAT in user boot mode, additional processings made by setting FMATS
are required: switching from user-boot-MAT selection state to user-MAT selection state, and
switching back to user-boot-MAT selection state after erasing completes.

The difference between the erasing procedures in user program mode and user boot mode depends
on whether the MAT is switched or not as shown in figure 21.15.
MAT switching is enabled by writing a specific value to FMATS. However note that while the
MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not allowed until
MAT switching is completed finished, and if an interrupt occurs, from which MAT the interrupt

21.6 Protection
There are three kinds of flash memory program/erase protection: hardware, software, and error
protection.
21.6.1 Hardware Protection
Programming and erasing of flash memory is forcibly disabled or suspended by hardware
protection. In this state, the downloading of an on-chip program and initialization of the flash
memory are possible. However, an activated program for programming or erasure cannot program
or erase locations in a user MAT, and the error in programming/erasing is reported in the FPFR
parameter.

power is initially supplied will not make
the LSI enter the reset state unless the
RES pin is held low until oscillation has
stabilized. In the case of a reset during
operation, hold the RES pin low for the
RES pulse width that is specified in the
section on AC characteristics. If the LSI is
reset during programming or erasure,
data in the flash memory is not
guaranteed. In this case, execute erasure
and then execute programming again.

21.6.3 Error Protection
Error protection is a mechanism for aborting programming or erasure when an error occurs, in the
form of the microcontroller getting out of control during programming/erasing of the flash
memory or operations that are not in accordance with the established procedures for
programming/erasing. Aborting programming or erasure in such cases prevents damage to the
flash memory due to excessive programming or erasing.
If the microcontroller malfunctions during programming/erasing of the flash memory, the FLER
bit in FCCS is set to 1 and the LSI enters the error protection state, thus aborting programming or
erasure.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 942 of 1168
REJ09B0344-0300
The FLER bit is set to 1 in the following conditions:
• When the relevant bank area of flash memory is read during programming/erasing (including a
vector read or an instruction fetch)
• When a SLEEP instruction (including software standby mode) is executed during
programming/erasing
Error protection is cancelled (FLER bit is cleared) only by a power-on reset.
Note that the reset signal should only be released after providing a reset input over a period longer
than the normal 100 μs. Since high voltages are applied during programming/erasing of the flash
memory, some voltage may still remain even after the error protection state has been entered. For
this reason, it is necessary to reduce the risk of damage to the flash memory by extending the reset
period so that the charge is released.
The state-transition diagram in figure 21.16 shows transitions to and from the error protection
state.

21.7 Usage Notes
21.7.1 Switching between User MAT and User Boot MAT
It is possible to switch between the user MAT and user boot MAT. However, the following
procedure is required because these MATs are allocated to address 0.
(Switching to the user boot MAT disables programming and erasing. Programming of the user
boot MAT must take place in boot mode or programmer mode.)
1. MAT switching by FMATS should always be executed from the on-chip RAM. The SH
microcontroller prefetches execution instructions. Therefore, a switchover during program
execution in the user MAT causes an instruction code in the user MAT to be prefetched or an
instruction in the newly selected user boot MAT to be prefetched, thus resulting in unstable
operation.
2. To ensure that the MAT that has been switched to is accessible, execute thirty-two NOP
instructions in on-chip RAM immediately after writing to FMATS of on-chip RAM (this
prevents access to the flash memory during MAT switching).
3. If an interrupt occurs during switching, there is no guarantee of which memory MAT is being
accessed.
Always mask the maskable interrupts before switching MATs. In addition, configuring the
system so that NMI interrupts do not occur during MAT switching is recommended.
4. After the MATs have been switched, take care because the interrupt vector table will also have
been switched.
If the same interrupt processings are to be executed before and after MAT switching or
interrupt requests cannot be disabled, transfer the interrupt processing routine to on-chip RAM,
and use the VBR setting to place the interrupt vector table in on chip RAM. In this case, make
sure the VBR setting change does not conflict with the interrupt occurrence.
5. Memory sizes of the user MAT and user boot MAT are different. When accessing the user
boot MAT, do not access addresses exceeding the 12-kbyte memory space. If access goes
beyond the 12-kbyte space, the values read are undefined.

H'AA) or the user boot MAT (FMATS is H'AA) on setting H'80000000 to VBR.
When VBR setting change conflicts with interrupt occurrence, whether the vector table before or
after VBR is changed is referenced may cause an error.
Therefore, for cases where VBR setting change may conflict with interrupt occurrence, prepare a
vector table to be referenced when VBR is H'00000000 (initial value) at the start of the user MAT
or user boot MAT.
(b) SCO Download Request and Interrupt Request
Download of the on-chip programming/erasing program that is initiated by setting the SCO bit in
FCCS to 1 generates a particular interrupt processing accompanied by MAT switchover.
Operation when the SCO download request and interrupt request conflicts is described below.
1. Contention between SCO download request and interrupt request
Figure 21.18 shows the timing of contention between execution of the instruction that sets the
SCO bit in FCCS to 1 and interrupt acceptance.

(2) Interrupts during Programming/Erasing
Ensure that NMI, IRQ, and all other interrupts are not generated during programming or
erasing of on-chip program code.
21.7.3 Other Notes
(1) Download Time of On-Chip Program
The programming program that includes the initialization routine and the erasing program that
includes the initialization routine are each 3 kbytes or less. Accordingly, when the CPU clock
frequency is 40 MHz, the download for each program takes approximately 10 ms at maximum.
(2) User Branch Processing Intervals
The intervals for executing the user branch processing differs in programming and erasing. The
processing phase also differs. Table 21.10 lists the maximum intervals for initiating the user
branch processing when the CPU clock frequency is 40 MHz.
Table 21.10 Initiation Intervals of User Branch Processing
Processing Name Maximum Interval
Programming Approximately 2 ms*
Erasing Approximately 15 ms*
Note: * Reference value
However, when operation is done with CPU clock of 40 MHz, maximum values of the time until
first user branch processing are as shown in table 21.11.
Table 21.11 Initial User Branch Processing Time
Processing Name Maximum
Programming Approximately 2 ms*
Erasing Approximately 15 ms*

(3) Write to Flash-Memory Related Registers by DMAC
While an instruction in on-chip RAM is being executed, the DMAC can write to the SCO bit in
FCCS that is used for a download request or FMATS that is used for MAT switching. Make sure
that these registers are not accidentally written to, otherwise an on-chip program may be
downloaded and destroy RAM or a MAT switchover may occur and the CPU get out of control.
(4) State in which Interrupts are Ignored
In the following modes or period, interrupt requests are ignored; they are not executed and the
interrupt sources are not retained.
• Boot mode
• Programmer mode
(5) Compatibility with Programming/Erasing Program of Conventional F-ZTAT SH
Microcontroller
A programming/erasing program for flash memory used in the conventional F-ZTAT SH
microcontroller which does not support download of the on-chip program by a SCO transfer
request cannot run in this LSI.
Be sure to download the on-chip program to execute programming/erasing of flash memory in this
LSI.
(6) Monitoring Runaway by WDT
Unlike the conventional F-ZTAT SH microcontroller, no countermeasures are available for a
runaway by WDT during programming/erasing by the downloaded on-chip program.
Prepare countermeasures (e.g. use of the user branch routine and periodic timer interrupts) for
WDT while taking the programming/erasing time into consideration as required.

(7) The Operating Frequency in On-Board Programming Mode
The frequency control register (FRQCR) should be set as follows in the erasing and programming
procedure, described in section 21.5, On-Board Programming Mode.
• Specify (Iφ: Bφ: Pφ) = (4: 4: 4) as the frequency division ratios of internal clocks.
When the input clock is 10 MHz, (Iφ: Bφ: Pφ) = (40 MHz: 40 MHz: 40MHz)
When the input clock is 8 MHz, (Iφ: Bφ: Pφ) = (32 MHz: 32 MHz: 32MHz)
• The following shows the frequency control register (FRQCR) values where (Iφ: Bφ: Pφ) = (4:
4: 4) as the frequency division ratios of internal clocks.
H'1000*
H'1111*
H'1333*
Note: * The CKOEN bit (bit 12) can be specified as either 0 or1.
(8) Programming the User MAT in User Program Mode
This LSI does not allow transitions from single chip mode to user program mode. Therefore, in
order to program the user MAT in user program mode, be sure to activate the LSI in MCU
extension mode 2 rather than in single chip mode.

21.8 Supplementary Information
21.8.1 Specifications of the Standard Serial Communications Interface in Boot Mode
The boot program activated in boot mode communicates with the host via the on-chip SCI of the
LSI. The specifications of the serial communications interface between the host and the boot
program are described below.
(1) States of Boot Program
The boot program has three states.
1. Bit-rate matching state
In this state, the boot program adjusts the bit rate to match that of the host. When the chip
starts up in boot mode, the boot program is activated and enters the bit-rate matching state, in
which it receives commands from the host and adjusts the bit rate accordingly. After bit-rate
matching is complete, the boot program proceeds to the inquiry-and-selection state.
2. Inquiry-and-selection state
In this state, the boot program responds to inquiry commands from the host. The device, clock
mode, and bit rate are selected in this state. After making these selections, the boot program
enters the programming/erasure state in response to the transition-to-programming/erasure
state command. The boot program transfers the erasure program to RAM and executes erasure
of the user MAT and user boot MAT before it enters the programming/erasure state.
3. Programming/erasure state
In this state, programming/erasure are executed. The boot program transfers the program for
programming/erasure to RAM in line with the command received from the host and executes
programming/erasure. It also performs sum checking and blank checking as directed by the
respective commands.
Figure 21.19 shows the flow of processing by the boot program.

(2) Bit-Rate Matching State
In bit-rate matching, the boot program measures the low-level intervals in a signal carrying H'00
data that is transmitted by the host, and calculates the bit rate from this. The bit rate can be
changed by the new-bit-rate selection command. On completion of bit-rate matching, the boot
program goes to the inquiry and selection state. The sequence of processing in bit-rate matching is
shown in figure 21.20.

(3) Communications Protocol
Formats in the communications protocol between the host and boot program after completion of
the bit-rate matching are as follows.
1. One-character command or one-character response
A command or response consisting of a single character used for an inquiry or the ACK code
indicating normal completion.
2. n-character command or n-character response
A command or response that requires n bytes of data, which is used as a selection command or
response to an inquiry. The length of programming data is treated separately below.
3. Error response
Response to a command in case of an error: two bytes, consisting of the error response and
error code.
4. 256-byte programming command
The command itself does not include data-size information. The data length is known from the
response to the command for inquiring about the programming size.
5. Response to a memory reading command
This response includes four bytes of size information.

The selection commands should be sent by the host in this order: device selection (H'10), clock-
mode selection (H'11), new bit rate selection (H'3F). These commands are mandatory. If the same
selection command is sent two or more times, the command that is sent last is effective.
All commands in the above table, except for the boot program state inquiry command (H'4F), are
valid until the boot program accepts the transition-to-programming/erasure state command (H'40).
That is, until the transition command is accepted, the host can continue to send commands listed in
the above table until it has made the necessary inquiries and selections. The host can send the boot
program state inquiry command (H'4F) even after acceptance of the transition-to-
programming/erasure state command (H'40) by the boot program.

The received data are checked in the following ways.
1. Input frequency
The value of the received input frequency is checked to see if it is within the range of the
minimum and maximum values of input frequency for the selected clock mode of the selected
device. A value outside the range generates an input frequency error.
2. Multiplier
The value of the received multiplier is checked to see if it matches a multiplier or divisor that
is available for the selected clock mode of the selected device. A value that does not match an
available ratio generates a frequency multiplier error.
3. Operating frequency
The operating frequency is calculated from the received input frequency and the frequency
multiplier or divisor. The input frequency is the frequency of the clock signal supplied to the
LSI, while the operating frequency is the frequency at which the LSI is actually driven. The
following formulae are used for this calculation.
Operating frequency = input frequency × multiplier, or
Operating frequency = input frequency / divisor
The calculated operating frequency is checked to see if it is within the range of the minimum
and maximum values of the operating frequency for the selected clock mode of the selected
device. A value outside the range generates an operating frequency error.
4. Bit rate
From the peripheral operating frequency (Pφ) and the bit rate (B), the value (= n) of the clock
select bits (CKS) in the serial mode register (SCSMR) and the value (= N) of the bit rate
register (SCBRR) are calculated, after which the error in the bit rate is calculated. This error is
checked to see if it is smaller than 4%. A result greater than or equal to 4% generates a bit rate
selection error. The following formula is use to calculate the error.
Error (%) = [ ] - 1 × 100
(N + 1) × B × 64 × 2
2n-1
Pφ × 10

When the new bit rate is selectable, the boot program returns an ACK code to the host and then
makes the register setting to select the new bit rate. The host then sends an ACK code at the
new bit rate, and the boot program responds to this with another ACK code, this time at the

(l) Transition to the Programming/Erasure State
In response to the transition to the programming/erasure state command, the boot program
transfers the erasing program and runs it to erase any data in the user MAT and then the user boot
MAT. On completion of this erasure, the boot program returns the ACK code and enters the
programming/erasure state.
Before sending the programming selection command and data for programming, the host must
select the device, clock mode, and new bit rate for the LSI by issuing the device selection
command, clock-mode selection command, new-bit-rate selection command, and then initiate the
transition to the programming/erasure state by sending the corresponding command to the boot
program.
Command H'40
• Command H'40 (1 byte): Transition to programming/erasure state
Response H'06
• Response H'06 (1 byte): Response to the transition-to-programming/erasure state command
This is returned as ACK when erasure of the user boot MAT and user MAT has succeeded
after transfer of the erasure program.

(5) Command Error
Command errors are generated by undefined commands, commands sent in an incorrect order, and
the inability to accept a command. For example, sending the clock-mode selection command
before device selection or an inquiry command after the transition-to-programming/erasure state
command generates a command error.
Error
response H'80 H'xx
• Error response H'80 (1 byte): Command error
• Command H'xx (1 byte): Received command
(6) Order of Commands
In the inquiry-and-selection state, commands should be sent in the following order.
1. Send the inquiry on supported devices command (H'20) to get the list of supported devices.
2. Select a device from the returned device information, and send the device selection command
(H'10) to select that device.
3. Send the inquiry on clock mode command (H'21) to get the available clock modes.
4. Select a clock mode from among the returned clock modes, and send the clock-mode selection
command (H'11).
5. After selection of the device and clock mode, send the commands to inquire about frequency
multipliers (H'22) and operating frequencies (H'23) to get the information required to select a
new bit rate.
6. Taking into account the returned information on the frequency multipliers and operating
frequencies, send a new-bit-rate selection command (H'3F).
7. After the device and clock mode have been selected, get the information required for
programming and erasure of the user boot MAT and user MAT by sending the commands to
inquire about the user boot MAT (H'24), user MAT (H'25), erasure block (H'26), and
programming size (H'27).
8. After making all necessary inquiries and the new bit rate selection, send the transition-to-
programming/erasure state command (H'40) to place the boot program in the
programming/erasure state.

(7) Programming/Erasure State
In this state, the boot program must select the form of programming corresponding to the
programming-selection command and then write data in response to 256-byte programming
commands, or perform erasure in block units in response to the erasure-selection and block-
erasure commands.
The programming and erasure commands are listed in table 21.13.

(8) Programming
Programming is performed by issuing a programming-selection command and the 256-byte
programming command.
Firstly, the host issues the programming-selection command to select the MAT to be programmed.
Two programming-selection commands are provided for the selection of either of the two target
areas.
1. Selection of user boot MAT programming
2. Selection of user MAT programming
Next, the host issues a 256-byte programming command. 256 bytes of data for programming by
the method selected by the preceding programming selection command are expected to follow the
command. To program more than 256 bytes, repeatedly issue 256-byte programming commands.
To terminate programming, the host should send another 256-byte programming command with
the address H'FFFFFFFF. On completion of programming, the boot program waits for the next
programming/erasure selection command.
To then program the other MAT, start by sending the programming select command.
The sequence of programming by programming-selection and 256-byte programming commands
is shown in figure 21.23.

programming (programming size). When less than 256 bytes of data are to be programmed, the
host should transmit the data after padding the vacant bytes with H'FF.
To terminate programming of a given MAT, send a 256-byte programming command with the
address field H'FFFFFFFF. This informs the boot program that all data for the selected MAT have
been sent; the boot program then waits for the next programming/erasure selection command.

(9) Erasure
Erasure is performed by issuing the erasure selection command and then one or more block
erasure commands.
Firstly, the host sends the erasure selection command to select erasure; after that, it sends a block
erasure command to actually erase a specific block. To erase multiple blocks, send further block
erasure commands. To terminate erasure, the host should send a block erasure command with the
block number H'FF. After this, the boot program waits for the next programming/erasure selection
command.
The sequence of erasure by the erasure selection command and block erasure command is shown
in figure 21.24.

21.8.2 Areas for Storage of the Procedural Program and Data for Programming
In the descriptions in the previous section, storable areas for the programming/erasing procedure
programs and program data are assumed to be in on-chip RAM. However, the procedure programs
and data can be stored in and executed from other areas (e.g. external address space) as long as the
following conditions are satisfied.
1. The on-chip programming/erasing program is downloaded from the address set by FTDAR in
on-chip RAM, therefore, this area is not available for use.
2. The on-chip programming/erasing program will use 128 bytes or more as a stack. Make sure
this area is reserved.
3. Since download by setting the SCO bit to 1 will cause the MATs to be switched, it should be
executed in on-chip RAM.
4. The flash memory is accessible until the start of programming or erasing, that is, until the
result of downloading has been decided.
Section 21 Flash Memory
Rev. 3.00 Mar. 04, 2009 Page 980 of 1168
REJ09B0344-0300
5. The flash memory is not accessible during programming and erasing, so programs must be
loaded into the on-chip RAM to perform these operations. Space in on-chip RAM other than
flash memory, or external bus space, must be available for each procedure program for
initiating programming or erasing, and for user programs at user branch destinations during
programming or erasing.
6. After programming/erasing, access to flash memory is inhibited until FKEY is cleared.
A reset state (RES = 0) for more than at least 100 μs must be taken when the LSI mode is
changed to reset on completion of a programming/erasing operation.
Transitions to the reset state during programming/erasing are inhibited. When the reset signal
is accidentally input to the LSI, a longer period in the reset state than usual (100 μs) is needed
before the reset signal is released.
7. Switching of the MATs by FMATS is needed for programming/erasing of the user MAT in
user boot mode. The program which switches the MATs should be executed from the on-chip
RAM. For details, see section 21.7.1, Switching between User MAT and User Boot MAT.
Please make sure you know which MAT is selected when switching the MATs.
8. When the program data storage area indicated by the FMPDR parameter in the programming
processing is within the flash memory area, an error will occur. Therefore, temporarily transfer
the program data to on-chip RAM to change the address set in FMPDR to an address other
than flash memory.
Based on these conditions, tables 21.16 and 21.17 show the areas in which the program data can
be stored and executed according to the operation type and mode.

21.9 Programmer Mode
In programmer mode, a PROM programmer can be used to perform programming/erasing via a
socket adapter, just as for a discrete flash memory. Use a PROM programmer that supports the
Renesas 512-kbyte flash memory on-chip MCU device type (F-ZTAT512DV3_15A).

Section 22 On-Chip RAM
This LSI has an on-chip RAM module which can be used to store instructions or data.
On-chip RAM operation and write access to the RAM can be enabled or disabled through the
RAM enable bits and RAM write enable bits.
22.1 Features
• Pages
The 32 Kbyte on-chip RAM is divided into four pages (pages 0 to 3).
The 24 Kbyte on-chip RAM is divided into three pages (pages 0 to 2).
• Memory map
The on-chip RAM is located in the address spaces shown in table 22.1, 22.2.

Page Address
Page 0 H'FFF80000 to H'FFF81FFF
Page 1 H'FFF82000 to H'FFF83FFF
Page 2 H'FFF84000 to H'FFF85FFF
• Ports
Each page has two independent read and write ports and is connected to the internal bus (I
bus), CPU instruction fetch bus (F bus), and CPU memory access bus (M bus). (Note that the F
bus is connected only to the read ports.)
The F bus and M bus are used for access by the CPU, and the I bus is used for access by the
DMAC.
• Priority
Section 22 On-Chip RAM
Rev. 3.00 Mar. 04, 2009 Page 988 of 1168
REJ09B0344-0300
When the same page is accessed from different buses simultaneously, the access is processed
according to the priority. The priority is I bus > M bus > F bus.
22.2 Usage Notes
22.2.1 Page Conflict
When the same page is accessed from different buses simultaneously, a conflict on the page
occurs. Although each access is completed correctly, this kind of conflict degrades the memory
access speed. Therefore, it is advisable to provide software measures to prevent such conflicts as
far as possible. For example, no conflict will arise if different memory or pages are accessed by
each bus.
22.2.2 RAME and RAMWE Bits
Before disabling memory operation or write access through the RAME or RAMWE bit, be sure to
read from any address and then write to the same address in each page; otherwise, the last written
data in each page may not be actually written to the RAM. For setting the RAME and RAMWE
bits, see section 23.3.5, System Control Register 1 (SYSCR1), and section 23.3.6, System Control
Register 2 (SYSCR2).

Section 23 Power-Down Modes
In power-down modes, operation of some of the internal peripheral modules and of the CPU stops.
This leads to reduced power consumption. These modes are canceled by a reset or interrupt.
23.1 Features
23.1.1 Power-Down Modes
This LSI has the following power-down modes and function:
1. Sleep mode
2. Software standby mode
3. Module standby function
Table 23.1 shows the transition conditions for entering the modes from the program execution
state, as well as the CPU and peripheral module states in each mode and the procedures for
canceling each mode.

23.1.2 Reset
A reset is used when the power is turned on or to run the LSI again from the initialized state.
There are two types of reset: power-on reset and manual reset. In a power-on reset, all the ongoing
processing is halted and any unprocessed events are canceled, and the reset processing starts
immediately. On the other hand, a manual reset does not interrupt processing to retain external
memory data. Conditions for generating a power-on reset or manual reset are as follows:
(1) Power-on Reset
1. A low level is input to the RES pin.
2. The watchdog timer (WDT) starts counting with the WT/IT bit in WTCSR set to 1 and with
the RSTS bit in WRCSR set to 0 while the RSRE bit in WRCSR is 1, and the counter
overflows.
3. The H-UDI reset is generated (for details on the H-UDI reset, see section 24, User
Debugging Interface (H-UDI)).
(2) Manual Reset
1. A low level is input to the MRES pin.
2. The WDT starts counting with the WT/IT bit in WTCSR set to 1 and with the RSTS bit in
WRCSR set to 1 while the RSRE bit in WRCSR is 1, and the counter overflows.

23.3.5 System Control Register 1 (SYSCR1)
SYSCR1 is an 8-bit readable/writable register that enables or disables access to the on-chip RAM.
SYSCR1 is initialized to H'FF by a power-on reset but retains its previous value by a manual reset
or in software standby mode. Only byte access is possible.
When an RAME bit is set to 1, the corresponding on-chip RAM area is enabled. When an RAME
bit is cleared to 0, the corresponding on-chip RAM area cannot be accessed. In this case, an
undefined value is returned when reading data or fetching an instruction from the on-chip RAM,
and writing to the on-chip RAM is ignored. The initial value of an RAME bit is 1.
Note that when clearing the RAME bit to 0 to disable the on-chip RAM, be sure to execute an
instruction to read from or write to the same arbitrary address in each page before setting the
RAME bit. If such an instruction is not executed, the data last written to each page may not be
written to the on-chip RAM. Furthermore, an instruction to access the on-chip RAM should not be
located immediately after the instruction to write to SYSCR1. If an on-chip RAM access
instruction is set, normal access is not guaranteed.
To enable the on-chip RAM by setting the RAME bit to 1, place an instruction to read data from
SYSCR1 immediately after an instruction to write to SYSCR1. If an instruction to access the on-
chip RAM is placed immediately after the instruction to write to SYSCR1, normal access is not
guaranteed.

23.3.6 System Control Register 2 (SYSCR2)
SYSCR2 is an 8-bit readable/writable register that enables or disables write to the on-chip RAM.
SYSCR2 is initialized to H'FF by a power-on reset but retains its previous value by a manual reset
or in software standby mode. Only byte access is valid.
When an RAMWE bit is set to 1, the corresponding on-chip RAM area is enabled. When an
RAMWE bit is cleared to 0, the corresponding on-chip RAM area cannot be written to. In this
case, writing to the on-chip RAM is ignored. The initial value of an RAMWE bit is 1.
Note that when clearing the RAMWE bit to 0 to disable the on-chip RAM, be sure to execute an
instruction to read from or write to the same arbitrary address in each page before setting the
RAMWE bit. If such an instruction is not executed, the data last written to each page may not be
written to the on-chip RAM. Furthermore, an instruction to access the on-chip RAM should not be
located immediately after the instruction to write to SYSCR2. If an on-chip RAM access
instruction is set, normal access is not guaranteed.
To enable the on-chip RAM by setting the RAMWE bit to 1, locate an instruction to read data
from SYSCR2 immediately after an instruction to write to SYSCR2. If an instruction to access the
on-chip RAM is located immediately after the instruction to write to SYSCR2, normal access is
not guaranteed.

23.4 Operation
23.4.1 Sleep Mode
(1) Transition to Sleep Mode
Executing the SLEEP instruction when the STBY bit in STBCR is 0 causes a transition from the
program execution state to sleep mode. Although the CPU halts immediately after executing the
SLEEP instruction, the contents of its internal registers remain unchanged. The on-chip modules
continue to run in sleep mode. Clock pulses are output continuously on the CK pin.
(2) Canceling Sleep Mode
Sleep mode is canceled by an interrupt (NMI, IRQ, and on-chip peripheral module), DMA address
error, or reset (manual reset or power-on reset).
• Canceling with an interrupt
When an NMI, IRQ, or on-chip peripheral module interrupt occurs, sleep mode is canceled and
interrupt exception handling is executed. When the priority level of the generated interrupt is
equal to or lower than the interrupt mask level that is set in the status register (SR) of the CPU,
or the interrupt by the on-chip peripheral module is disabled on the module side, the interrupt
request is not accepted and sleep mode is not canceled.
• Canceling with a DMA address error
When a DMA address error occurs, sleep mode is canceled and DMA address error exception
handling is executed.
• Canceling with a reset
Sleep mode is canceled by a power-on reset or a manual reset.
23.4.2 Software Standby Mode
(1) Transition to Software Standby Mode
The LSI switches from a program execution state to software standby mode by executing the
SLEEP instruction when the STBY bit in STBCR is 1. In software standby mode, not only the
CPU but also the clock and on-chip peripheral modules halt. The clock output from the CK pin
also halts.
The contents of the CPU remain unchanged. Some registers of on-chip peripheral modules are,
however, initialized. Table 23.4 shows the states of peripheral module registers in software
standby mode.

The CPU takes one cycle to finish writing to STBCR, and then executes processing for the next
instruction. However, it takes one or more cycles to actually write. Therefore, execute a SLEEP
instruction after reading STBCR to have the values written to STBCR by the CPU to be definitely
reflected in the SLEEP instruction.

The procedure for switching to software standby mode is as follows:
1. Clear the TME bit in the WDT's timer control register (WTCSR) to 0 to stop the WDT.
2. Set the WDT's timer counter (WTCNT) to 0 and the CKS[2:0] bits in WTCSR to appropriate
values to secure the specified oscillation settling time.
3. After setting the STBY bit in STBCR to 1, read STBCR. Then, execute a SLEEP instruction.

(2) Exit from Software Standby Mode
Software standby mode is exited by interrupts (NMI or IRQ) or a reset (manual reset or power-on
reset).
(a) Exit from Software Standby by an Interrupt
When the falling edge or rising edge of the NMI pin (selected by the NMI edge select bit (NMIE)
in interrupt control register 0 (ICR0) of the interrupt controller (INTC)) or the falling edge or
rising edge of an IRQ pin (IRQ7 to IRQ0) (selected by the IRQn sense select bits (IRQn1S and
IRQn0S) in interrupt control register 1 (ICR1) of the interrupt controller (INTC)) is detected,
clock oscillation is started. This clock pulse is supplied only to the oscillation settling counter
(WDT) used to count the oscillation settling time.
After the elapse of the time set in the clock select bits (CKS[2:0]) in the watchdog timer
control/status register (WTCSR) of the WDT before the transition to software standby mode, the
WDT overflow occurs. Since this overflow indicates that the clock has been stabilized, the clock
pulse will be supplied to the entire chip after this overflow. Software standby mode is cleared and
NMI interrupt exception handling (IRQ interrupt exception handling in the case of IRRQ) starts.
When canceling software standby mode by the NMI interrupt or IRQ interrupt, set the CKS[2:0]
bits so that the WDT overflow period will be equal to or longer than the oscillation settling time.
The clock output phase of the CK pin may be unstable immediately after detecting an interrupt
and until software standby mode is canceled. When software standby mode is canceled by the
falling edge of the NMI pin, the NMI pin should be high when the CPU enters software standby
mode (when the clock pulse stops) and should be low when the CPU returns from software
standby mode (when the clock is initiated after the oscillation settling). When software standby
mode is canceled by the rising edge of the NMI pin, the NMI pin should be low when the CPU
enters software standby mode (when the clock pulse stops) and should be high when the CPU
returns from software standby mode (when the clock is initiated after the oscillation settling) (This
is the same with the IRQ pin.)
(b) Exit from Software Standby by a Reset
When the RES or MRES pin is driven low, this LSI enters the power-on reset or manual reset
state, and software standby mode is exited.
Keep the RES or MRES pin low until the clock oscillation settles.
Internal clock pulses are output continuously on the CK pin.

23.4.3 Software Standby Mode Application Example
This example describes a transition to software standby mode on the falling edge of the NMI
signal, and cancellation on the rising edge of the NMI signal. The timing is shown in figure 23.1.
When the NMI pin is changed from high to low level while the NMI edge select bit (NMIE) in
ICR is set to 0 (falling edge detection), the NMI interrupt is accepted. When the NMIE bit is set to
1 (rising edge detection) by the NMI exception service routine, the STBY bit in STBCR is set to 1,
and a SLEEP instruction is executed, software standby mode is entered. Thereafter, software
standby mode is canceled when the NMI pin is changed from low to high level.

23.4.4 Module Standby Function
(1) Transition to Module Standby Function
Setting the standby control register MSTP bits to 1 halts the supply of clocks to the corresponding
on-chip peripheral modules. This function can be used to reduce the power consumption in normal
mode and sleep mode. Disable a module before placing it in module standby mode. In addition, do
not access the module's registers while it is in the module standby state.
The register states are the same as those in software standby mode. For details of register states,
see table 23.4.
However, the states of the CMT and DAC registers are exceptional. In the CMT, all registers are
initialized in software standby mode, but retain their previous values in module standby mode. In
the DAC, all registers retain their previous values in software standby mode, but are initialized in
module standby mode.
(2) Canceling Module Standby Function
The module standby function can be canceled by clearing the MSTP bits to 0, or by a power-on
reset (only possible for H-UDI, UBC, and DMAC). When taking a module out of the module
standby state by clearing the corresponding MSTP bit to 0, read the MSTP bit to confirm that it
has been cleared to 0.

TCK Input Data is serially supplied to the H-UDI from
the data input pin (TDI), and output from
the data output pin (TDO), in
synchronization with this clock.
Mode select input pin TMS Input The state of the TAP control circuit is
determined by changing this signal in
synchronization with TCK. For the protocol,
see figure 24.2.
H-UDI reset input pin TRST Input Input is accepted asynchronously with
respect to TCK, and when low, the H-UDI is
reset. TRST must be low for a constant
period when power is turned on regardless
of using the H-UDI function. See section
24.4.2, Reset Configuration, for more
information.
H-UDI serial data input pin TDI Input Data transfer to the H-UDI is executed by
changing this signal in synchronization with
TCK.
H-UDI serial data output pin TDO Output Data read from the H-UDI is executed by
reading this pin in synchronization with
TCK. The initial value of the data output
timing is the TCK falling edge. This can be
changed to the TCK rising edge by
inputting the TDO change timing switch
command to SDIR. See section 24.4.3,
TDO Output Timing, for more information.
ASE mode select pin ASEMD* Input If a low level is input at the ASEMD pin
while the RES pin is asserted, ASE mode is
entered; if a high level is input, normal
mode is entered. In ASE mode, dedicated
emulator function can be used. The input
level at the ASEMD pin should be held for
at least one cycle after RES negation.
Note: * When the emulator is not in use, fix this pin to the high level.

Figure 24.2 TAP Controller State Transitions
Note: The transition condition is the TMS value at the rising edge of TCK. The TDI value is
sampled at the rising edge of TCK; shifting occurs at the falling edge of TCK. For details
on change timing of the TDO value, see section 24.4.3, TDO Output Timing. The TDO is
at high impedance, except with shift-DR and shift-IR states. During the change to TRST =
0, there is a transition to test-logic-reset asynchronously with TCK.

Notes: 1. Performs normal mode and ASE mode settings
ASEMD = H, normal mode
ASEMD = L, ASE mode
2. In ASE mode, reset hold is entered if the TRST pin is driven low while the RES pin is
negated. In this state, the CPU does not start up. When TRST is driven high, H-UDI
operation is enabled, but the CPU does not start up. The reset hold state is cancelled
by a power-on reset.
24.4.3 TDO Output Timing
The initial value of the TDO change timing is to perform data output from the TDO pin on the
TCK falling edge. However, setting a TDO change timing switch command in SDIR via the H-
UDI pin and passing the Update-IR state synchronizes the TDO change timing to the TCK rising
edge. Thereafter the TDO change timing cannot be changed unless a power-on reset that asserts
the TRST pin simultaneously is performed.

24.4.4 H-UDI Reset
An H-UDI reset is executed by setting an H-UDI reset assert command in SDIR. An H-UDI reset
is of the same kind as a power-on reset. An H-UDI reset is released by setting an H-UDI reset
negate command. The required time between the H-UDI reset assert command and H-UDI reset
negate command is the same as time for keeping the RES pin low to apply a power-on reset.

24.4.5 H-UDI Interrupt
The H-UDI interrupt function generates an interrupt by setting a command from the H-UDI in
SDIR. An H-UDI interrupt is a general exception/interrupt operation, resulting in fetching the
exception service routine start address from the exception handling vector table, jumping to that
address, and starting program execution from that address. This interrupt request has a fixed
priority level of 15.
H-UDI interrupts are accepted in sleep mode, but not in software standby mode.

24.5 Usage Notes
1. An H-UDI command, once set, will not be modified as long as another command is not set
again from the H-UDI. If the same command is to be set continuously, the command must be
set after a command (BYPASS mode, etc.) that does not affect chip operations is once set.
2. In software standby mode and H-UDI module standby state, all of the functions in the H-UDI
cannot be used. To retain the TAP status before and after standby mode, keep TCK high before
entering standby mode.

Section 26 List of Registers
This section gives information on the on-chip I/O registers of this LSI in the following structures.
1. Register Addresses (by functional module, in order of the corresponding section numbers)
• Registers are described by functional module, in order of the corresponding section numbers.
• Access to reserved addresses which are not described in this register address list is prohibited.
• When registers consist of 16 or 32 bits, the addresses of the MSBs are given when big-endian
mode is selected.
2. Register Bits
• Bit configurations of the registers are described in the same order as the Register Addresses
(by functional module, in order of the corresponding section numbers).
• Reserved bits are indicated by — in the bit name.
• No entry in the bit-name column indicates that the whole register is allocated as a counter or
for holding data.
3. Register States in Each Operating Mode
• Register states are described in the same order as the Register Addresses (by functional
module, in order of the corresponding section numbers).
• For the initial state of each bit, refer to the description of the register in the corresponding
section.
• The register states described are for the basic operating modes. If there is a specific reset for an
on-chip peripheral module, refer to the section on that on-chip peripheral module.
4. Notes when Writing to the On-Chip Peripheral Modules
• To access an on-chip module register, two or more peripheral module clock (Pf) cycles are
required. Care must be taken in system design. When the CPU writes data to the internal
peripheral registers, the CPU performs the succeeding instructions without waiting for the
completion of writing to registers. For example, a case is described here in which the system is
transferring to the software standby mode for power savings. To make this transition, the
SLEEP instruction must be performed after setting the STBY bit in the STBCR register to 1.
However a dummy read of the STBCR register is required before executing the SLEEP
instruction. If a dummy read is omitted, the CPU executes the SLEEP instruction before the
STBY bit is set to 1, thus the system enters sleep mode not software standby mode. A dummy
read of the STBCR register is indispensable to complete writing to the STBY bit. To reflect the
change by internal peripheral registers while performing the succeeding instructions, execute a
dummy read of registers to which write instruction is given and then perform the succeeding
instructions.

Note: VccQ ≥ Vcc = PLLVcc is recommended. Either VccQ, Vcc, or PLLVcc power supply can be
turned on or off first, though, an undefined period appears until Vcc rises to the Min. voltage
or after Vcc passes the Min. voltage. During these periods, pin or internal states become
undefined. Design the system so that such undefined states do not cause a system
malfunction. To avoid an increase in the current consumption during the undefined period
at power-on, it is recommended that VccQ, Vcc, and PLLVcc be turned on simultaneously.
This undefined period can be eliminated by turning on the power supplies in the order
shown in figure 27.2.

Notes: To prevent the pin and internal states from being undefined, VccQ and AVcc should be
kept GND voltage level (0 V) and they should not be placed in floating state until Vcc
reaches the Min. voltage. In addition, the RES pin should be input low to place power-
on reset state. In this case, care must be taken for the power consumption increase
caused by sink current because each pin is placed in low-impedance state until VccQ
reaches the Min. voltage.

Notes: 1. RES, NMI, and IRQ7 to IRQ0 are asynchronous signals. When these setup times are
observed, a change of these signals is detected at the clock rising edge. If the setup
times are not observed, detection of a signal change may be delayed until the next
rising edge of the clock.
2. In standby mode or when the clock multiplication ratio is changed, tRESW = tOSC2 (Min. 10
ms).
3. In standby mode, tRESW = tOSC2 (Min. 10 ms).

793 Description amended
When using the A/D converter or D/A converter, make settings
such that AVcc = 5.0 V ±0.5 V and AVss = Vss. When the A/D
converter and D/A converter are not used, make settings such
that AVcc = VccQ and AVss = VssQ, and do not leave the
AVcc and AVss pins open.
17.7.2 AVREF Pin
Setting Range
793 Description amended
When using the A/D converter or D/A converter, set AVREF to
a level between 4.5 V and AVcc. When the A/D converter and
D/A converter are not used, make settings such that AVREF =
AVcc, and do not leave the AVREF pin open.
The setting of the AVREFVss pin should always be such that
AVREFVss = AVss, and do not leave AVREFVss open. If
these conditions are not met, the reliability of the SH7211 may
be adversely affected.

980 Description amended
5. The flash memory is not accessible during programming
and erasing, so programs must be loaded into the on-chip
RAM to perform these operations. Space in on-chip RAM
other than flash memory, or external bus space, must be
available for each procedure program for initiating
programming or erasing, and for user programs at user
branch destinations during programming or erasing.

Register 2 (SYSCR2)
1003 Note added
Note: This is a reserved bit on versions with 24 KB of RAM. Its
value is always 1 when read. Always write 1 to this bit.
27.2 Power-on/Power-
off Sequence
1083 Note amended
To prevent the pin and internal states from being undefined,
VccQ and AVcc should be kept GND voltage level (0 V) and
they should not be placed in floating state until Vcc reaches
the Min. voltage. In addition, the RES pin should be input low
to place power-on reset state. In this case, care must be taken
for the power consumption increase caused by sink current
because each pin is placed in low-impedance state until VccQ
reaches the Min. voltage.
27.3 DC Characteristics
Table 27.3 DC
Characteristics (1)
[Common Items]
1084 Note amended
Caution: When neither the A/D converter nor the D/A
converter is in use, do not leave the AVcc, AVss,
AVREF, and AVREFVss pins open.
