For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MC9S12DT128B Device User Guide -- V01.09 Freescale Semiconductor, Inc... * * * - Do not write or read BDLC registers (after reset: address range $00E8 - $00EF), if using a derivative without BDLC (see Table 0-1). - Do not write or read IIC registers (after reset: address range $00E0 - $00E7), if using a 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] Port J pull-up resistors are enabled out of reset on all four pins (7:6 and 1:0). Therefore care must 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. For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc... Freescale Semiconductor, Inc. MC9S12DT128B Device User Guide -- V01.09 - Port M[7:6] PM7:6 must be configured as outputs or their pull resistors must be enabled to avoid floating inputs. - Port P6 PP6 must be configured as output or its pull resistor must be enabled to avoid a floating input. - Port S[7:4] PS7:4 must be configured as outputs or their pull resistors must be enabled to avoid floating inputs. - PAD[15:8] (ATD1 channels) Out of reset the ATD1 is disabled preventing current flows in the pins.

On reset all the device clocks are derived from the EXTAL input frequency. XTAL is the crystal output. Freescale Semiconductor, Inc... 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. XFC R MCU CP CS VDDPLL VDDPLL 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.

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. Freescale Semiconductor, Inc... 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 mode and provide limited mode switching during operation. The states of the MODC, MODB, and MODA pins are latched into these bits on the rising edge of the reset signal. 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.

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. For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MC9S12DT128B Device User Guide -- V01.09 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. Freescale Semiconductor, Inc... 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, the user can erase and program the FLASH security bits to the 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). 4.4.1 Stop 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. The internal CPU signals (address and databus) will be fully static. All peripherals stay active. 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.

MC9S12DT128B Device User Guide -- V01.09 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 Freescale Semiconductor, Inc... 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. For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. 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. Freescale Semiconductor, Inc... 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 > VDD5) 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.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.

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 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MC9S12DT128B Device User Guide -- V01.09 specifies results in an error of less than 1/2 LSB (2.5mV) at the maximum leakage current. If device or operating conditions are less than worst case or leakage-induced error is acceptable, 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 Freescale Semiconductor, Inc... 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 * RS * IINJ, with IINJ being the sum of the currents injected into the two pins adjacent to the converted channe Table A-9 ATD Electrical Characteristics Conditions are shown in Table A-4 unless otherwise noted Num C Rating Symbol Min Typ Max Unit RS - - 1 K 10 22 pF 2.5 mA 1 C Max input Source Resistance 2 Total Input Capacitance T Non Sampling Sampling 3 C Disruptive Analog Input Current INA 4 C Coupling Ratio positive current injection Kp 10-4 A/A 5 C Coupling Ratio negative current injection Kn 10-2 A/A CINN CINS -2.5 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

A.3.1 NVM timing Freescale Semiconductor, Inc... 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 fNVMOP and can be calculated according to the following formula. 1 1 t swpgm = 9 --------------------- + 25 ---------f NVMOP f bus 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: 1 1 t bwpgm = 4 --------------------- + 9 ---------f NVMOP f bus The time to program a whole row is: t brpgm = t swpgm + 31 t bwpgm Burst programming is more than 2 times faster than single word programming.

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.

MC9S12DT128B Device User Guide -- V01.09 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. Freescale Semiconductor, Inc... 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.

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.
