5.2.3 System Power Distribution
In this chip, the power distribution is divided into three segments.
z Analog power from AVDD and AVSS provides the power for analog components
operation.
z Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 2.5 V power for digital operation and I/O pins.
The outputs of internal voltage regulators, LDO and VDD33, require an external capacitor which
should be located close to the corresponding pin. Analog power (AVDD) should be the same
voltage level of the digital power (VDD). Figure 5-2 shows the power distribution of NuMicro™

5.2.5 System Timer (SysTick)
The Cortex-M0 includes an integrated system timer, SysTick. SysTick provides a simple, 24-bit
clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism. The
counter can be used as a Real Time Operating System (RTOS) tick timer or as a simple counter.
When system timer is enabled, it will count down from the value in the SysTick Current Value
Register (SYST_CVR) to zero, and reload (wrap) to the value in the SysTick Reload Value
Register (SYST_RVR) on the next clock cycle, then decrement on subsequent clocks. When the
counter transitions to zero, the COUNTFLAG status bit is set. The COUNTFLAG bit clears on
reads.
The SYST_CVR value is UNKNOWN on reset. Software should write to the register to clear it to
zero before enabling the feature. This ensures the timer will count from the SYST_RVR value
rather than an arbitrary value when it is enabled.
If the SYST_RVR is zero, the timer will be maintained with a current value of zero after it is
reloaded with this value. This mechanism can be used to disable the feature independently from
the timer enable bit.
For more detailed information, please refer to the documents “ARM® Cortex™-M0 Technical
Reference Manual” and “ARM® v6-M Architecture Reference Manual”.

5.2.6 Nested Vectored Interrupt Controller (NVIC)
Cortex-M0 provides an interrupt controller as an integral part of the exception mode, named as
“Nested Vectored Interrupt Controller (NVIC)”. It is closely coupled to the processor kernel and
provides following features:
z Nested and Vectored interrupt support
z Automatic processor state saving and restoration
z Reduced and deterministic interrupt latency
The NVIC prioritizes and handles all supported exceptions. All exceptions are handled in “Handler
Mode”. This NVIC architecture supports 32 (IRQ[31:0]) discrete interrupts with 4 levels of priority.
All of the interrupts and most of the system exceptions can be configured to different priority
levels. When an interrupt occurs, the NVIC will compare the priority of the new interrupt to the
current running one’s priority. If the priority of the new interrupt is higher than the current one, the
new interrupt handler will override the current handler.
When any interrupts is accepted, the starting address of the interrupt service routine (ISR) is
fetched from a vector table in memory. There is no need to determine which interrupt is accepted
and branch to the starting address of the correlated ISR by software. While the starting address is
fetched, NVIC will also automatically save processor state including the registers “PC, PSR, LR,
R0~R3, R12” to the stack. At the end of the ISR, the NVIC will restore the mentioned registers
from stack and resume the normal execution. Thus it will take less and deterministic time to
process the interrupt request.
The NVIC supports “Tail Chaining” which handles back-to-back interrupts efficiently without the
overhead of states saving and restoration and therefore reduces delay time in switching to
pending ISR at the end of current ISR. The NVIC also supports “Late Arrival” which improves the
efficiency of concurrent ISRs. When a higher priority interrupt request occurs before the current
ISR starts to execute (at the stage of state saving and starting address fetching), the NVIC will
give priority to the higher one without delay penalty. Thus it advances the real-time capability.
For more detailed information, please refer to the documents “ARM® Cortex™-M0 Technical
Reference Manual” and “ARM® v6-M Architecture Reference Manual”.

5.2.6.1 Exception Model and System Interrupt Map
Table 5-2 lists the exception model supported by NuMicro™ NUC100 Series. Software can set
four levels of priority on some of these exceptions as well as on all interrupts. The highest user-
configurable priority is denoted as “0” and the lowest priority is denoted as “3”. The default priority
of all the user-configurable interrupts is “0”. Note that priority “0” is treated as the fourth priority on
the system, after three system exceptions “Reset”, “NMI” and “Hard Fault”.

5.2.6.2 Vector Table
When any interrupts is accepted, the processor will automatically fetch the starting address of the
interrupt service routine (ISR) from a vector table in memory. For ARMv6-M, the vector table base
address is fixed at 0x00000000. The vector table contains the initialization value for the stack
pointer on reset, and the entry point addresses for all exception handlers. The vector number on
previous page defines the order of entries in the vector table associated with exception handler
entry as illustrated in previous section.
Vector Table Word Offset Description
0 SP_main – The Main stack pointer
Vector Number Exception Entry Pointer using that Vector Number
Table 5-4 Vector Table Format
5.2.6.3 Operation Description
NVIC interrupts can be enabled and disabled by writing to their corresponding Interrupt Set-
Enable or Interrupt Clear-Enable register bit-field. The registers use a write-1-to-enable and write-
1-to-clear policy, both registers reading back the current enabled state of the corresponding
interrupts. When an interrupt is disabled, interrupt assertion will cause the interrupt to become
Pending, however, the interrupt will not activate. If an interrupt is Active when it is disabled, it
remains in its Active state until cleared by reset or an exception return. Clearing the enable bit
prevents new activations of the associated interrupt.
NVIC interrupts can be pended/un-pended using a complementary pair of registers to those used
to enable/disable the interrupts, named the Set-Pending Register and Clear-Pending Register
respectively. The registers use a write-1-to-enable and write-1-to-clear policy, both registers
reading back the current pended state of the corresponding interrupts. The Clear-Pending
Register has no effect on the execution status of an Active interrupt.
NVIC interrupts are prioritized by updating an 8-bit field within a 32-bit register (each register
supporting four interrupts).
The general registers associated with the NVIC are all accessible from a block of memory in the
System Control Space and will be described in next section.

5.3 Clock Controller
5.3.1 Overview
The clock controller generates the clocks for the whole chip, including system clocks and all
peripheral clocks. The clock controller also implements the power control function with the
individually clock ON/OFF control, clock source selection and a clock divider. The chip will not
enter power down mode until CPU sets the power down enable bit (PWR_DOWN_EN) and
Cortex-M0 core executes the WFI instruction. After that, chip enter power down mode and wait for
wake-up interrupt source triggered to leave power down mode. In the power down mode, the
clock controller turns off the external 4~24 MHz high speed crystal and internal 22.1184 MHz high
speed oscillator to reduce the overall system power consumption.

5.3.6 Frequency Divider Output
This device is equipped a power-of-2 frequency divider which is composed by16 chained divide-
by-2 shift registers. One of the 16 shift register outputs selected by a sixteen to one multiplexer is
reflected to CLKO function pin. Therefore there are 16 options of power-of-2 divided clocks with
the frequency from Fin/21 to Fin/216 where Fin is input clock frequency to the clock divider.
The output formula is F
out = Fin/2(N+1), where Fin is the input clock frequency, Fout is the clock
divider output frequency and N is the 4-bit value in FSEL (FRQDIV[3:0]).
When write 1 to DIVIDER_EN (FRQDIV[4]), the chained counter starts to count. When write 0 to
DIVIDER_EN (FRQDIV[4]), the chained counter continuously runs till divided clock reaches low
state and stay in low state.

of the 80 pins is independent and has the corresponding register bits to control the pin mode
function and data.
The I/O type of each of I/O pins can be configured by software individually as input, output, open-
drain or quasi-bidirectional mode. After reset, the I/O type of all pins stay in quasi-bidirectional
mode and port data register GPIOx_DOUT[15:0] resets to 0x0000_FFFF. Each I/O pin equips a
very weakly individual pull-up resistor which is about 110 KΩ~300 KΩ for VDD is from 5.0 V to 2.5
V.

5.5 I2C Serial Interface Controller (Master/Slave) (I2C)
5.5.1 Overview
I2C is a two-wire, bi-directional serial bus that provides a simple and efficient method of data
exchange between devices. The I2C standard is a true multi-master bus including collision
detection and arbitration that prevents data corruption if two or more masters attempt to control
the bus simultaneously.
Data is transferred between a Master and a Slave synchronously to SCL on the SDA line on a
byte-by-byte basis. Each data byte is 8-bit long. There is one SCL clock pulse for each data bit
with the MSB being transmitted first. An acknowledge bit follows each transferred byte. Each bit is
sampled during the high period of SCL; therefore, the SDA line may be changed only during the
low period of SCL and must be held stable during the high period of SCL. A transition on the SDA
line while SCL is high is interpreted as a command (START or STOP). Please refer to the Figure
5-9 for more detail I2C BUS Timing.
Figure 5-9 I2C Bus Timing
The device’s on-chip I2C logic provides the serial interface that meets the I2C bus standard mode
specification. The I2C port handles byte transfers autonomously. To enable this port, the bit ENS1
in I2CON should be set to '1'. The I2C H/W interfaces to the I2C bus via two pins: SDA and SCL.
Pull up resistor is needed for I2C operation as these are open drain pins. When the I/O pins are
used as I2C port, user must set the pins function to I2C in advance.

5.6 PWM Generator and Capture Timer (PWM)
5.6.1 Overview
NuMicro™ NUC130/NUC140 has 2 sets of PWM group supports total 4 sets of PWM Generators
which can be configured as 8 independent PWM outputs, PWM0~PWM7, or as 4 complementary
PWM pairs, (PWM0, PWM1), (PWM2, PWM3), (PWM4, PWM5) and (PWM6, PWM7) with 4
programmable dead-zone generators.
Each PWM Generator has one 8-bit prescaler, one clock divider with 5 divided frequencies (1,
1/2, 1/4, 1/8, 1/16), two PWM Timers including two clock selectors, two 16-bit PWM down-
counters for PWM period control, two 16-bit comparators for PWM duty control and one dead-
zone generator. The 4 sets of PWM Generators provide eight independent PWM interrupt flags
which are set by hardware when the corresponding PWM period down counter reaches zero.
Each PWM interrupt source with its corresponding enable bit can cause CPU to request PWM
interrupt. The PWM generators can be configured as one-shot mode to produce only one PWM
cycle signal or auto-reload mode to output PWM waveform continuously.
When PCR.DZEN01 is set, PWM0 and PWM1 perform complementary PWM paired function; the
paired PWM period, duty and dead-time are determined by PWM0 timer and Dead-zone
generator 0. Similarly, the complementary PWM pairs of (PWM2, PWM3), (PWM4, PWM5) and
(PWM6, PWM7) are controlled by PWM2, PWM4 and PWM6 timers and Dead-zone generator 2,
4 and 6, respectively.
To prevent PWM driving output pin with unsteady waveform, the 16-bit period down counter and
16-bit comparator are implemented with double buffer. When user writes data to
counter/comparator buffer registers the updated value will be load into the 16-bit down counter/
comparator at the time down counter reaching zero. The double buffering feature avoids glitch at
PWM outputs.
When the 16-bit period down counter reaches zero, the interrupt request is generated. If PWM-
timer is set as auto-reload mode, when the down counter reaches zero, it is reloaded with PWM
Counter Register (CNRx) automatically then start decreasing, repeatedly. If the PWM-timer is set
as one-shot mode, the down counter will stop and generate one interrupt request when it reaches
zero.
The value of PWM counter comparator is used for pulse high width modulation. The counter
control logic changes the output to high level when down-counter value matches the value of
compare register.
The alternate feature of the PWM-timer is digital input Capture function. If Capture function is
enabled the PWM output pin is switched as capture input mode. The Capture0 and PWM0 share
one timer which is included in PWM0 and the Capture1 and PWM1 share PWM1 timer, and etc.
Therefore user must setup the PWM-timer before enable Capture feature. After capture feature is
enabled, the capture always latched PWM-counter to Capture Rising Latch Register (CRLR)
when input channel has a rising transition and latched PWM-counter to Capture Falling Latch
Register (CFLR) when input channel has a falling transition. Capture channel 0 interrupt is
programmable by setting CCR0.CRL_IE0[1] (Rising latch Interrupt enable) and
CCR0.CFL_IE0[2]] (Falling latch Interrupt enable) to decide the condition of interrupt occur.
Capture channel 1 has the same feature by setting CCR0.CRL_IE1[17] and CCR0.CFL_IE1[18].
And capture channel 2 to channel 3 on each group have the same feature by setting the
corresponding control bits in CCR2. For each group, whenever Capture issues Interrupt 0/1/2/3,
the PWM counter 0/1/2/3 will be reload at this moment.
The maximum captured frequency that PWM can capture is confined by the capture interrupt
latency. When capture interrupt occurred, software will do at least three steps, they are: Read

- 38 - Revision V3.02
PIIR to get interrupt source and Read CRLRx/CFLRx(x=0~3) to get capture value and finally write
1 to clear PIIR to zero. If interrupt latency will take time T0 to finish, the capture signal mustn’t
transition during this interval (T0). In this case, the maximum capture frequency will be 1/T0. For
example:
HCLK = 50 MHz, PWM_CLK = 25 MHz, Interrupt latency is 900 ns
So the maximum capture frequency will is 1/900ns ≈ 1000 kHz

5.10 Watchdog Timer (WDT)
5.10.1 Overview
The purpose of Watchdog Timer is to perform a system reset when system runs into an unknown
state. This prevents system from hanging for an infinite period of time. Besides, this Watchdog
Timer supports another function to wake-up chip from power down mode. The watchdog timer
includes an 18-bit free running counter with programmable time-out intervals. Table 5-5 show the
watchdog timeout interval selection and Figure 5-64 shows the timing of watchdog interrupt signal
and reset signal.
Setting WTE (WDTCR [7]) enables the watchdog timer and the WDT counter starts counting up.
When the counter reaches the selected time-out interval, Watchdog timer interrupt flag WTIF will
be set immediately to request a WDT interrupt if the watchdog timer interrupt enable bit WTIE is
set, in the meanwhile, a specified delay time (1024 * TWDT) follows the time-out event. User must
set WTR (WDTCR [0]) (Watchdog timer reset) high to reset the 18-bit WDT counter to avoid chip
from Watchdog timer reset before the delay time expires. WTR bit is cleared automatically by
hardware after WDT counter is reset. There are eight time-out intervals with specific delay time
which are selected by Watchdog timer interval select bits WTIS (WDTCR [10:8]). If the WDT
counter has not been cleared after the specific delay time expires, the watchdog timer will set
Watchdog Timer Reset Flag (WTRF) high and reset chip. This reset will last 63 WDT clocks (TRST)
then chip restarts executing program from reset vector (0x0000_0000). WTRF will not be cleared
by Watchdog reset. User may poll WTRF by software to recognize the reset source. WDT also
provides wake-up function. When chip is powered down and the Watchdog Timer Wake-up
Function Enable bit (WDTR[4]) is set, if the WDT counter reaches the specific time interval
defined by WTIS (WDTCR [10:8]) , the chip is waken up from power down state. First example, if
WTIS is set as 000, the specific time interval for chip to wake up from power down state is 24 *
TWDT. When power down command is set by software, then, chip enters power down state. After
24 * TWDT time is elapsed, chip is waken up from power down state. Second example, if WTIS
(WDTCR [10:8]) is set as 111, the specific time interval for chip to wake up from power down
state is 218 * TWDT. If power down command is set by software, then, chip enters power down
state. After 218 * TWDT time is elapsed, chip is waken up from power down state. Notice if WTRE
(WDTCR [1]) is set to 1, after chip is waken up, software should clear the Watchdog Timer
counter by setting WTR(WDTCR [0]) to 1 as soon as possible. Otherwise, if the Watchdog Timer
counter is not cleared by setting WTR (WDTCR [0]) to 1 before time starting from waking up to
software clearing Watchdog Timer counter is over 1024 * TWDT , the chip is reset by Watchdog
Timer.

5.11 UART Interface Controller (UART)
NuMicro™ NUC130/NUC140 provides up to three channels of Universal Asynchronous
Receiver/Transmitters (UART). UART0 supports High Speed UART and UART1~2 perform
Normal Speed UART, besides, only UART0 and UART1 support flow control function.
5.11.1 Overview
The Universal Asynchronous Receiver/Transmitter (UART) performs a serial-to-parallel
conversion on data received from the peripheral, and a parallel-to-serial conversion on data
transmitted from the CPU. The UART controller also supports IrDA SIR Function, LIN
master/slave mode function and RS-485 mode functions. Each UART channel supports seven
types of interrupts including transmitter FIFO empty interrupt (INT_THRE), receiver threshold
level reaching interrupt (INT_RDA), line status interrupt (parity error or framing error or break
interrupt) (INT_RLS), receiver buffer time out interrupt (INT_TOUT), MODEM/Wake-up status
interrupt (INT_MODEM), Buffer error interrupt (INT_BUF_ERR) and LIN receiver break field
detected interrupt (INT_LIN_RX_BREAK). Interrupts of UART0 and UART2 share the interrupt
number 12 (vector number is 28); Interrupt number 13 (vector number is 29) only supports
UART1 interrupt. Refer to Nested Vectored Interrupt Controller chapter for System Interrupt Map.
The UART0 is built-in with a 64-byte transmitter FIFO (TX_FIFO) and a 64-byte receiver FIFO
(RX_FIFO) that reduces the number of interrupts presented to the CPU and the UART1~2 are
equipped 16-byte transmitter FIFO (TX_FIFO) and 16-byte receiver FIFO (RX_FIFO). The CPU
can read the status of the UART at any time during the operation. The reported status information
includes the type and condition of the transfer operations being performed by the UART, as well
as 4 error conditions (parity error, framing error, break interrupt and buffer error) probably occur
while receiving data. The UART includes a programmable baud rate generator that is capable of
dividing clock input by divisors to produce the serial clock that transmitter and receiver need. The
baud rate equation is Baud Rate = UART_CLK / M * [BRD + 2], where M and BRD are defined in
Baud Rate Divider Register (UA_BAUD). Table 5-6 lists the equations in the various conditions
and Table 5-7 list the UART baud rate setting table.

Table 5-7 UART Baud Rate Setting Table
The UART0 and UART1 controllers support auto-flow control function that uses two low-level
signals, /CTS (clear-to-send) and /RTS (request-to-send), to control the flow of data transfer
between the UART and external devices (ex: Modem). When auto-flow is enabled, the UART is
not allowed to receive data until the UART asserts /RTS to external device. When the number of
bytes in the RX FIFO equals the value of RTS_TRI_LEV (UA_FCR [19:16]), the /RTS is de-
asserted. The UART sends data out when UART controller detects /CTS is asserted from external
device. If a valid asserted /CTS is not detected the UART controller will not send data out.
The UART controllers also provides Serial IrDA (SIR, Serial Infrared) function (User must set
IrDA_EN (UA_FUN_SEL [1]) to enable IrDA function). The SIR specification defines a short-range
infrared asynchronous serial transmission mode with one start bit, 8 data bits, and 1 stop bit. The
maximum data rate is 115.2 Kbps (half duplex). The IrDA SIR block contains an IrDA SIR
Protocol encoder/decoder. The IrDA SIR protocol is half-duplex only. So it cannot transmit and
receive data at the same time. The IrDA SIR physical layer specifies a minimum 10ms transfer
delay between transmission and reception. This delay feature must be implemented by software.
The alternate function of UART controllers is LIN (Local Interconnect Network) function. The LIN
mode is selected by setting the UA_FUN_SEL[1:0] to ’01’. In LIN mode, one start bit and 8-bit
data format with 1-bit stop bit are required in accordance with the LIN standard.
For NuMicro™ NUC100 Series, another alternate function of UART controllers is RS-485 9-bit
mode function, and direction control provided by RTS pin or can program GPIO (PB.2 for RTS0
and PB.6 for RTS1) to implement the function by software. The RS-485 mode is selected by
setting the UA_FUN_SEL register to select RS-485 function. The RS-485 driver control is
implemented using the RTS control signal from an asynchronous serial port to enable the RS-485
driver. In RS-485 mode, many characteristics of the RX and TX are same as UART.

For communication on a CAN network, individual Message Objects are configured. The Message
Objects and Identifier Masks for acceptance filtering of received messages are stored in the
Message RAM. All functions concerning the handling of messages are implemented in the
Message Handler. These functions include acceptance filtering, the transfer of messages
between the CAN Core and the Message RAM, and the handling of transmission requests as well
as the generation of the module interrupt.
The register set of the C_CAN can be accessed directly by the software through the module
interface. These registers are used to control/configure the CAN Core and the Message Handler
and to access the Message RAM.

5.13 PS/2 Device Controller (PS2D)
5.13.1 Overview
PS/2 device controller provides basic timing control for PS/2 communication. All communication
between the device and the host is managed through the CLK and DATA pins. Unlike PS/2
keyboard or mouse device controller, the received/transmit code needs to be translated as
meaningful code by firmware. The device controller generates the CLK signal after receiving a
request to send, but host has ultimate control over communication. DATA sent from the host to
the device is read on the rising edge and DATA sent from device to the host is change after rising
edge. A 16 bytes FIFO is used to reduce CPU intervention. S/W can select 1 to 16 bytes for a
continuous transmission.
5.13.2 Features
z Host communication inhibit and request to send detection
z Reception frame error detection
z Programmable 1 to 16 bytes transmit buffer to reduce CPU intervention
