derivative without IIC (see Table 0-1).
– Do not write or read Byteflight registers (after reset: address range $0300 - $035F), if using a
derivative without Byteflight registers (see Table 0-1).
• Interrupts
– Fill the four CAN1 interrupt vectors ($FFA8 - $FFAF) according to your coding policies for
unused interrupts, if using a derivative without CAN1 (see Table 0-1).
– Fill the BDLC interrupt vector ($FFC2, $FFC3) according to your coding policies for unused
interrupts, if using a derivative without BDLC (see Table 0-1).
– Fill the IIC interrupt vector ($FFC0, $FFC1) according to your coding policies for unused
interrupts, if using a derivative without IIC (see Table 0-1).
– Fill the four Byteflight interrupt vectors ($FFA0 - $FFA7) according to your coding policies for
unused interrupts, if using a derivative without Byteflight (see Table 0-1).
• Ports
– The CAN1 pin functionality (TXCAN1, RXCAN1) is not available on port PM3 and PM2, if
using a derivative without CAN1 (see Table 0-1).
– The BDLC pin functionality (TXB, RXB) is not available on port PM1 and PM0, if using a
derivative without BDLC (see Table 0-1).
– The IIC pin functionality (SCL, SCA) is not available on port PJ7 and PJ6, if using a derivative
without IIC (see Table 0-1).
– The Byteflight pin functionality (BF_PSLM, BF_PERR, BF_PROK, BF_PSYN, TX_BF,
RX_BF) is not available on port PM7, PM6, PM5, PM4, PM3 and PM2, if using a derivative
without Byteflight (see Table 0-1).
• Pins not available in 80 pin QFP package
–Port H
In order to avoid floating nodes the ports should be either configured as outputs by setting the
data direction register (DDRH at Base+$0262) to $FF, or enabling the pull resistors by writing
a $FF to the pull enable register (PERH at Base+$0264).
–Port J[1:0]
PortJpull-upresistorsare enabled out of reset on all four pins (7:6 and 1:0).Thereforecaremust
be taken not to disable the pull enables on PJ[1:0] by clearing the bits PERJ1 and PERJ0 at
Base+$026C.
–Port K
Port K pull-up resistors are enabled out of reset, i.e. Bit 7 = PUKE = 1 in the register PUCR at
Base+$000C. Therefore care must be taken not to clear this bit.

MC9S12DT128B Device User Guide — V01.09
Section 1 Introduction
1.1 Overview
The MC9S12DT128B microcontroller unit (MCU) is a 16-bit device composed of standard on-chip
peripherals including a 16-bit central processing unit (HCS12 CPU), 128K bytes of Flash EEPROM, 8K
bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), two
serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit
analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link
Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital
I/O lines with interrupt and wakeup capability, three CAN 2.0 A, B software compatible modules
(MSCAN12), a Byteflight module and an Inter-IC Bus. The MC9S12DT128B has full 16-bit data paths
throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory
can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and
performance to be adjusted to suit operational requirements.

2.3 Detailed Signal Descriptions
2.3.1 EXTAL, XTAL — Oscillator Pins
EXTAL and XTAL are the crystal driver and external clock pins. On reset all the device clocks are derived
from the EXTAL input frequency. XTAL is the crystal output.
2.3.2 RESET — External Reset Pin
An active low bidirectional control signal, it acts as an input to initialize the MCU to a known start-up
state, and an output when an internal MCU function causes a reset.
2.3.3 TEST — Test Pin
This input only pin is reserved for test.
NOTE:
The TEST pin must be tied to VSS in all applications.
2.3.4 XFC — PLL Loop Filter Pin
PLL loop filter. Please ask your Motorola representative for the interactive application note to compute
PLL loop filter elements. Any current leakage on this pin must be avoided.
Figure 2-3 PLL Loop Filter Connections
2.3.5 BKGD / TAGHI / MODC — Background Debug, Tag High, and Mode Pin
The BKGD/TAGHI/MODC pin is used as a pseudo-open-drain pin for the background debug
communication. In MCU expanded modes of operation when instruction tagging is on, an input low on
this pin during the falling edge of E-clock tags the high half of the instruction word being read into the
instruction queue. It is used as a MCU operating mode select pin during reset. The state of this pin is
latched to the MODC bit at the rising edge of RESET. This pin has a permanently enabled pull-up device.

PE7 is a general purpose input or output pin. During MCU expanded modes of operation, the NOACC
signal, when enabled, is used to indicate that the current bus cycle is an unused or “free” cycle. This signal
will assert when the CPU is not using the bus.
The XCLKS is an input signal which controls whether a crystal in combination with the internal Colpitts
(low power) oscillator is used or whether Pierce oscillator/external clock circuitry is used. The state of this
pin is latched at the rising edge of RESET. If the input is a logic low the EXTAL pin is configured for an
external clock drive. If input is a logic high an oscillator circuit is configured on EXTAL and XTAL. Since
this pin is an input with a pull-up device during reset, if the pin is left floating, the default configuration is
an oscillator circuit on EXTAL and XTAL.

Section 4 Modes of Operation
4.1 Overview
Eight possible modes determine the operating configuration of the MC9S12DT128B. Each mode has an
associated default memory map and external bus configuration controlled by a further pin.
Three low power modes exist for the device.
4.2 Chip Configuration Summary
The operating mode out of reset is determined by the states of the MODC, MODB, and MODA pins during
reset (Table 4-1). The MODC, MODB, and MODA bits in the MODE register show the current operating
modeandprovide limited mode switching during operation. The states of theMODC,MODB,andMODA
pinsarelatched into these bits on the rising edgeoftheresetsignal. The ROMCTL signal allows the setting
of the ROMON bit in the MISC register thus controlling whether the internal Flash is visible in the
memory map. ROMON = 1 mean the Flash is visible in the memory map. The state of the ROMCTL pin
is latched into the ROMON bit in the MISC register on the rising edge of the reset signal.
For further explanation on the modes refer to the Core User Guide.

4.3 Security
The device will make available a security feature preventing the unauthorized read and write of the
memory contents. This feature allows:
• Protection of the contents of FLASH,
• Protection of the contents of EEPROM,
• Operation in single-chip mode, No BDM possible
• Operation from external memory with internal FLASH and EEPROM disabled.
The user must be reminded that part of the security must lie with the user’s code. An extreme example
would be user’s code that dumps the contents of the internal program. This code would defeat the purpose
of security. At the same time the user may also wish to put a back door in the user’s program. An example
of this is the user downloads a key through the SCI which allows access to a programming routine that
updates parameters stored in EEPROM.
4.3.1 Securing the Microcontroller
Once the user has programmed the FLASH and EEPROM (if desired), the part can be secured by
programming the security bits located in the FLASH module. These non-volatile bits will keep the part
secured through resetting the part and through powering down the part.
The security byte resides in a portion of the Flash array.
Check the Flash Block User Guide for more details on the security configuration.
4.3.2 Operation of the Secured Microcontroller
4.3.2.1 Normal Single Chip Mode
This will be the most common usage of the secured part. Everything will appear the same as if the part was
not secured with the exception of BDM operation. The BDM operation will be blocked.
4.3.2.2 Executing from External Memory
The user may wish to execute from external space with a secured microcontroller. This is accomplished
by resetting directly into expanded mode. The internal FLASH and EEPROM will be disabled. BDM
operations will be blocked.

4.3.3 Unsecuring the Microcontroller
In order to unsecure the microcontroller, the internal FLASH and EEPROM must be erased. This can be
done through an external program in expanded mode.
Once the user has erased the FLASH and EEPROM, the part can be reset into special single chip mode.
This invokes a program that verifies the erasure of the internal FLASH and EEPROM. Once this program
completes,theuser can erase and program the FLASH securitybitstothe unsecured state. This is generally
done through the BDM, but the user could also change to expanded mode (by writing the mode bits
through the BDM) and jumping to an external program (again through BDM commands). Note that if the
part goes through a reset before the security bits are reprogrammed to the unsecure state, the part will be
secured again.
4.4 Low Power Modes
The microcontroller features three main low power modes. Consult the respective Block User Guide for
information on the module behavior in Stop, Pseudo Stop, and Wait Mode. An important source of
information about the clock system is the Clock and Reset Generator User Guide (CRG).

Executing the CPU STOP instruction stops all clocks and the oscillator thus putting the chip in fully static
mode. Wake up from this mode can be done via reset or external interrupts.
4.4.2 Pseudo Stop
This mode is entered by executing the CPU STOP instruction. In this mode the oscillator is still running
and the Real Time Interrupt (RTI) or Watchdog (COP) sub module can stay active. Other peripherals are
turned off. This mode consumes more current than the full STOP mode, but the wake up time from this
mode is significantly shorter.
4.4.3 Wait
This mode is entered by executing the CPU WAI instruction. In this mode the CPU will not execute
instructions.Theinternal CPU signals (address and databus) will be fully static.Allperipheralsstayactive.
For further power consumption the peripherals can individually turn off their local clocks.
4.4.4 Run
Although this is not a low power mode, unused peripheral modules should not be enabled in order to save
power.

Section 22 Printed Circuit Board Layout Proposal
The PCB must be carefully laid out to ensure proper operation of the voltage regulator as well as of the
MCU itself. The following rules must be observed:
• Every supply pair must be decoupled by a ceramic capacitor connected as near as possible to the
corresponding pins (C1 – C6).
• Central point of the ground star should be the VSSR pin.
• Use low ohmic low inductance connections between VSS1, VSS2 and VSSR.
• VSSPLL must be directly connected to VSSR.
• Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area for C7,
C8, C11 and Q1 as small as possible.
• Do not place other signals or supplies underneath area occupied by C7, C8, C10 and Q1 and the
connection area to the MCU.
• Central power input should be fed in at the VDDA/VSSA pins.

Appendix A Electrical Characteristics
A.1 General
This introduction is intended to give an overview on several common topics like power supply, current
injection etc.
A.1.1 Parameter Classification
The electrical parameters shown in this supplement are guaranteed by various methods. To give the
customer a better understanding the following classification is used and the parameters are tagged
accordingly in the tables where appropriate.
P:
Those parameters are guaranteed during production testing on each individual device.
C:
Those parameters are achieved by the design characterization by measuring a statistically relevant
sample size across process variations. They are regularly verified by production monitors.
T:
Those parameters are achieved by design characterization on a small sample size from typical
devices. All values shown in the typical column are within this category.
D:
Those parameters are derived mainly from simulations.
A.1.2 Power Supply
The MC9S12DT128B utilizes several pins to supply power to the I/O ports, A/D converter, oscillator and
PLL as well as the digital core.
The VDDA, VSSA pair supplies the A/D converter and the resistor ladder of the internal voltage regulator.
The VDDX, VSSX, VDDR and VSSR pairs supply the I/O pins ,VDDR supplies also the internal voltage
regulator.
VDD1, VSS1, VDD2 and VSS2 are the supply pins for the digital logic, VDDPLL, VSSPLL supply the
oscillator and the PLL.
VSS1 and VSS2 are internally connected by metal.
VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for ESD
protection.

MC9S12DT128B Device User Guide — V01.09
NOTE:
In the following context VDD5 is used for either VDDA, VDDR and VDDX; VSS5
is used for either VSSA, VSSR and VSSX unless otherwise noted.
IDD5 denotes the sum of the currents flowing into the VDDA, VDDX and VDDR
pins.
VDD is used for VDD1, VDD2 and VDDPLL, VSS is used for VSS1, VSS2 and
VSSPLL.
IDD is used for the sum of the currents flowing into VDD1 and VDD2.
A.1.3 Pins
There are four groups of functional pins.
A.1.3.1 5V I/O pins
Those I/O pins have a nominal level of 5V. This class of pins is comprised of all port I/O pins, the analog
inputs, BKGD pin and the RESET inputs.The internal structure of all those pins is identical, however some
of the functionality may be disabled. E.g. for the analog inputs the output drivers, pull-up and pull-down
resistors are disabled permanently.
A.1.3.2 Analog Reference
This class is made up by the two VRH and VRL pins.
A.1.3.3 Oscillator
The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5V level. They are supplied
by VDDPLL.
A.1.3.4 TEST
This pin is used for production testing only.
A.1.3.5 VREGEN
This pin is used to enable the on chip voltage regulator.
A.1.4 Current Injection
Power supply must maintain regulation within operating VDD5 or VDD range during instantaneous and
operating maximum current conditions. If positive injection current (Vin >V
DD5) is greater than IDD5, the
injection current may flow out of VDD5 and could result in external power supply going out of regulation.
Insure external VDD5 load will shunt current greater than maximum injection current. This will be the
greatest risk when the MCU is not consuming power; e.g. if no system clock is present, or if clock rate is
very low which would reduce overall power consumption.

A.1.5 Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima
is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the
device.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (e.g., either VSS5 or VDD5).
A.1.6 ESD Protection and Latch-up Immunity
All ESD testing is in conformity with CDF-AEC-Q100 Stress test qualification for Automotive Grade
Integrated Circuits. During the device qualification ESD stresses were performed for the Human Body
Model (HBM), the Machine Model (MM) and the Charge Device Model.

A.1.10 Supply Currents
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
A.1.10.1 Measurement Conditions
All measurements are without output loads. Unless otherwise noted the currents are measured in single
chip mode, internal voltage regulator enabled and at 25MHz bus frequency using a 4MHz oscillator in
Colpitts mode. Production testing is performed using a square wave signal at the EXTAL input.
A.1.10.2 Additional Remarks
In expanded modes the currents flowing in the system are highly dependent on the load at the address, data
and control signals as well as on the duty cycle of those signals. No generally applicable numbers can be

A.2 ATD Characteristics
This section describes the characteristics of the analog to digital converter.
A.2.1 ATD Operating Characteristics
The Table A-8 shows conditions under which the ATD operates.
The following constraints exist to obtain full-scale, full range results:
VSSA ≤VRL ≤VIN ≤VRH ≤VDDA.This constraint exists since the sample buffer amplifier can not drive
beyond the power supply levels that it ties to. If the input level goes outside of this range it will effectively
be clipped.
Table A-8 ATD Operating Characteristics
A.2.2 Factors influencing accuracy
Three factors – source resistance, source capacitance and current injection – have an influence on the
accuracy of the ATD.
A.2.2.1 Source Resistance:
Due to the input pin leakage current as specified in Table A-6 in conjunction with the source resistance
there will be a voltage drop from the signal source to the ATD input. The maximum source resistance RS

specifies results in an error of less than 1/2 LSB (2.5mV) at the maximum leakage current. If device or
operatingconditionsare less than worst case or leakage-induced errorisacceptable,larger values of source
resistance is allowed.
A.2.2.2 Source capacitance
When sampling an additional internal capacitor is switched to the input. This can cause a voltage drop due
to charge sharing with the external and the pin capacitance. For a maximum sampling error of the input
voltage ≤ 1LSB, then the external filter capacitor, Cf≥ 1024 * (CINS– CINN).
A.2.2.3 Current injection
There are two cases to consider.
1. A current is injected into the channel being converted. The channel being stressed has conversion
values of $3FF ($FF in 8-bit mode) for analog inputs greater than VRH and $000 for values less than
VRL unless the current is higher than specified as disruptive conditions.
2. Current is injected into pins in the neighborhood of the channel being converted. A portion of this
current is picked up by the channel (coupling ratio K), This additional current impacts the accuracy
of the conversion depending on the source resistance.
The additional input voltage error on the converted channel can be calculated as VERR =K*R

A.3 NVM, Flash and EEPROM
NOTE:
Unless otherwise noted the abbreviation NVM (Non Volatile Memory) is used for
both Flash and EEPROM.
A.3.1 NVM timing
The time base for all NVM program or erase operations is derived from the oscillator. A minimum
oscillator frequency fNVMOSC is required for performing program or erase operations. The NVM modules
do not have any means to monitor the frequency and will not prevent program or erase operation at
frequencies above or below the specified minimum. Attempting to program or erase the NVM modules at
a lower frequency a full program or erase transition is not assured.
The Flash and EEPROM program and erase operations are timed using a clock derived from the oscillator
using the FCLKDIV and ECLKDIV registers respectively. The frequency of this clock must be set within
the limits specified as fNVMOP.
The minimum program and erase times shown in Table A-11 are calculated for maximum fNVMOP and
maximum fbus. The maximum times are calculated for minimum fNVMOP and a fbus of 2MHz.
A.3.1.1 Single Word Programming
The programming time for single word programming is dependant on the bus frequency as a well as on
the frequency f¨NVMOP and can be calculated according to the following formula.
A.3.1.2 Burst Programming
This applies only to the Flash where up to 32 words in a row can be programmed consecutively using burst
programming by keeping the command pipeline filled. The time to program a consecutive word can be
calculated as:
The time to program a whole row is:
Burst programming is more than 2 times faster than single word programming.

The setup times can be ignored for this operation.
A.3.1.4 Mass Erase
Erasing a NVM block takes:
The setup times can be ignored for this operation.
A.3.1.5 Blank Check
The time it takes to perform a blank check on the Flash or EEPROM is dependant on the location of the
first non-blank word starting at relative address zero. It takes one bus cycle per word to verify plus a setup
of the command.

A.5 Reset, Oscillator and PLL
This section summarizes the electrical characteristics of the various startup scenarios for Oscillator and
Phase-Locked-Loop (PLL).
A.5.1 Startup
Table A-14 summarizes several startup characteristics explained in this section. Detailed description of
the startup behavior can be found in the Clock and Reset Generator (CRG) Block User Guide.
Table A-14 Startup Characteristics
A.5.1.1 POR
The release level VPORR and the assert level VPORA are derived from the VDD Supply. They are also valid
if the device is powered externally. After releasing the POR reset the oscillator and the clock quality check
are started. If after a time tCQOUT no valid oscillation is detected, the MCU will start using the internal self
clock. The fastest startup time possible is given by nuposc.
A.5.1.2 SRAM Data Retention
Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing
code when VDD5 is out of specification limits, the SRAM contents integrity is guaranteed if after the reset
the PORF bit in the CRG Flags Register has not been set.
A.5.1.3 External Reset
When external reset is asserted for a time greater than PWRSTL the CRG module generates an internal
reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an
oscillation before reset.
A.5.1.4 Stop Recovery
Out of STOP the controller can be woken up by an external interrupt. A clock quality check as after POR
is performed before releasing the clocks to the system.
Conditions are shown in Table A-4 unless otherwise noted

A.5.1.5 Pseudo Stop and Wait Recovery
The recovery from Pseudo STOP and Wait are essentially the same since the oscillator was not stopped in
both modes. The controller can be woken up by internal or external interrupts. After twrs the CPU starts
fetching the interrupt vector.
A.5.2 Oscillator
The device features an internal Colpitts and Pierce oscillator. The selection of Colpitts oscillator or Pierce
oscillator/external clock depends on the XCLKS signal which is sampled during reset.By asserting the
XCLKS input during reset this oscillator can be bypassed allowing the input of a square wave. Before
asserting the oscillator to the internal system clocks the quality of the oscillation is checked for each start
from either power-on, STOP or oscillator fail. tCQOUT specifies the maximum time before switching to the
internal self clock mode after POR or STOP if a proper oscillation is not detected. The quality check also
determines the minimum oscillator start-up time tUPOSC. The device also features a clock monitor. A
Clock Monitor Failure is asserted if the frequency of the incoming clock signal is below the Assert
Frequency fCMFA. Table A-15 Oscillator Characteristics

A.5.3 Phase Locked Loop
The oscillator provides the reference clock for the PLL. The PLL´s Voltage Controlled Oscillator (VCO)
is also the system clock source in self clock mode.
A.5.3.1 XFC Component Selection
This section describes the selection of the XFC components to achieve a good filter characteristics.

The following procedure can be used to calculate the resistance and capacitance values using typical
values for K1, f1 and ich from Table A-16.
The grey boxes show the calculation for fVCO = 50MHz and fref = 1MHz. E.g., these frequencies are used
for fOSC = 4MHz and a 25MHz bus clock.

The capacitance Cs can now be calculated as:
The capacitance Cp should be chosen in the range of:
A.5.3.2 Jitter Information
The basic functionality of the PLL is shown in Figure A-2. With each transition of the clock fcmp, the
deviation from the reference clock fref is measured and input voltage to the VCO is adjusted
accordingly.The adjustment is done continuously with no abrupt changes in the clock output frequency.
Noise, voltage, temperature and other factors cause slight variations in the control loop resulting in a clock
jitter. This jitter affects the real minimum and maximum clock periods as illustrated in Figure A-3.

This is very important to notice with respect to timers, serial modules where a pre-scaler will eliminate the
effect of the jitter to a large extent.
