NOTE: Signals shown in bold are not available in the 80 pin package. NOTE: If the port pins are not bonded out in the chosen package the user should initialize the registers to be inputs with enabled pull resistance to avoid excess current consumption. This applies to the following pins: (80QFP): Port A[7:0], Port B[7:0], Port E[6,5,3,2], Port K[7:0], Port U[7:4] 79 Device User Guide — 9S12E128DGV1/D V01.04 2.3 Detailed Signal Descriptions 2.3.1 EXTAL, XTAL — Oscillator Pins EXTAL and XTAL are the external clock and crystal driver 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 RESET is an active low bidirectional control signal that acts as an input to initialize the MCU to a known start-up state. It also acts as an open-drain output to indicate that an internal failure has been detected in either the clock monitor or COP watchdog circuit. External circuitry connected to the RESET pin should not include a large capacitance that would interfere with the ability of this signal to rise to a valid logic one within 32 ECLK cycles after the low drive is released. Upon detection of any reset, an internal circuit drives the RESET pin low and a clocked reset sequence controls when the MCU can begin normal processing The RESET pin includes an internal pull up device. 2.3.3 TEST — Test Pin The TEST pin is reserved for test and must be tied to VSS in all applications. 2.3.4 XFC — PLL Loop Filter Pin Dedicated pin used to create the PLL loop filter. See appendix B.4.3.1and the CRG Block Guide for more detailed information. 2.3.5 BKGD / TAGHI / MODC — Background Debug, Tag High & Mode Pin The BKGD / TAGHI / MODC pin is used as a pseudo-open-drain pin for the background debug communication. 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. 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. This pin always has an internal pull up. 2.3.6 PA[7:0] / ADDR[15:8] / DATA[15:8] — Port A I/O Pins PA[7:0] are general purpose input or output pins. In MCU expanded modes of operation, these pins are used for the multiplexed external address and data bus. PA[7:0] pins are not available in the 80 pin package version. 2.3.7 PB[7:0] / ADDR[7:0] / DATA[7:0] — Port B I/O Pins PB[7:0] are general purpose input or output pins. In MCU expanded modes of operation, these pins are used for the multiplexed external address and data bus. PB[7:0] pins are not available in the 80 pin package version. 80 Device User Guide — 9S12E128DGV1/D V01.04 2.3.8 PE7 / NOACC / XCLKS — Port E I/O Pin 7 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 or a Pierce Oscillator. If the input is a logic high a Colpitts 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 a Colpitts oscillator circuit on EXTAL and XTAL. 81 Device User Guide — 9S12E128DGV1/D V01.04 Figure 2-3 Colpitts Oscillator Connections (PE7=1) EXTAL CDC * MCU C1 Crystal or ceramic resonator XTAL C2 VSSPLL * Due to the nature of a translated ground Colpitts oscillator a DC voltage bias is applied to the crystal .Please contact the crystal manufacturer for crystal DC Figure 2-4 Pierce Oscillator Connections (PE7=0) EXTAL C1 MCU XTAL RB RS* Crystal or ceramic resonator C2 VSSPLL * Rs can be zero (shorted) when use with higher frequency crystals. Refer to manufacturer’s data. 2.3.9 PE6 / MODB / IPIPE1 — Port E I/O Pin 6 PE6 is a general purpose input or output pin. It is used as a MCU operating mode select pin during reset. The state of this pin is latched to the MODB bit at the rising edge of RESET. This pin is shared with the 82 Device User Guide — 9S12E128DGV1/D V01.04 instruction queue tracking signal IPIPE1. This pin is an input with a pull-down device which is only active when RESET is low. PE6 is not available in the 80 pin package version. 2.3.10 PE5 / MODA / IPIPE0 — Port E I/O Pin 5 PE5 is a general purpose input or output pin. It is used as a MCU operating mode select pin during reset. The state of this pin is latched to the MODA bit at the rising edge of RESET. This pin is shared with the instruction queue tracking signal IPIPE0. This pin is an input with a pull-down device which is only active when RESET is low. PE5 is not available in the 80 pin package version. 2.3.11 PE4 / ECLK— Port E I/O Pin 4 / E-Clock Output PE4 is a general purpose input or output pin. In Normal Single Chip mode PE4 is configured with an active pull-up while in reset and immediately out of reset. The pullup can be turned off by clearing PUPEE in the PUCR register. In all modes except Normal Single Chip Mode, the PE4 pin is initially configured as the output connection for the internal bus clock(ECLK). ECLK is used as a timing reference and to demultiplex the address and data in expanded modes. The ECLK frequency is equal to 1/2 the crystal frequency out of reset. The ECLK output function depends upon the settings of the NECLK bit in the PEAR register, the IVIS bit in the MODE register and the ESTR bit in the EBICTL register. All clocks, including the ECLK, are halted when the MCU is in STOP mode. It is possible to configure the MCU to interface to slow external memory. ECLK can be stretched for such accesses. The PE4 pin is initially configured as ECLK output with stretch in all expanded modes. Reference the MISC register (EXSTR[1:0] bits) for more information. In normal expanded narrow mode, the ECLK is available for use in external select decode logic or as a constant speed clock for use in the external application system. 2.3.12 PE3 / LSTRB / TAGLO — Port E I/O Pin 3 / Low-Byte Strobe (LSTRB) PE3 can be used as a general-purpose I/O in all modes and is an input with an active pull-up out of reset. The pullup can be turned off by clearing PUPEE in the PUCR register. PE3 can also be configured as a Low-Byte Strobe (LSTRB). The LSTRB signal is used in write operations, so external low byte writes will not be possible until this function is enabled. LSTRB can be enabled by setting the LSTRE bit in the PEAR register. In Expanded Wide and Emulation Narrow modes, and when BDM tagging is enabled, the LSTRB function is multiplexed with the TAGLO function. When enabled a logic zero on the TAGLO pin at the falling edge of ECLK will tag the low byte of an instruction word being read into the instruction queue. PE3 is not available in the 80 pin package version. 2.3.13 PE2 / R/W — Port E I/O Pin 2 / Read/Write PE2 can be used as a general-purpose I/O in all modes and is configured an input with an active pull-up out of reset. The pullup can be turned off by clearing PUPEE in the PUCR register. If the read/write function is required it should be enabled by setting the RDWE bit in the PEAR register. External writes will not be possible until the read/write function is enabled. The PE2 pin is not available in the 80 pin package version. 83 Device User Guide — 9S12E128DGV1/D V01.04 2.3.14 PE1 / IRQ — Port E input Pin 1 / Maskable Interrupt Pin PE1 is always an input and can always be read. The PE1 pin is also the IRQ input used for requesting an asynchronous interrupt to the MCU. During reset, the I bit in the condition code register (CCR) is set and any IRQ interrupt is masked until software enables it by clearing the I bit. The IRQ is software programmable to either falling edge-sensitive triggering or level-sensitive triggering based on the setting of the IRQE bit in the IRQCR register. The IRQ is always enabled and configured to level-sensitive triggering out of reset. It can be disabled by clearing IRQEN bit in the IRQCR register. There is an active pull-up on this pin while in reset and immediately out of reset. The pullup can be turned off by clearing PUPEE in the PUCR register. 2.3.15 PE0 / XIRQ — Port E input Pin 0 / Non Maskable Interrupt Pin PE0 is always an input and can always be read. The PE0 pin is also the XIRQ input for requesting a nonmaskable asynchronous interrupt to the MCU. During reset, the X bit in the condition code register (CCR) is set and any XIRQ interrupt is masked until MCU software enables it by clearing the X bit. Because the XIRQ input is level sensitive triggered, it can be connected to a multiple-source wired-OR network. There is an active pull-up on this pin while in reset and immediately out of reset. The pullup can be turned off by clearing PUPEE in the PUCR register. 2.3.16 PK7 / ECS / ROMCTL — Port K I/O Pin 7 PK7 is a general purpose input or output pin. During MCU expanded modes of operation, when the EMK bit in the MODE register is set to 1, this pin is used as the emulation chip select output (ECS). In expanded modes the PK7 pin can be used to determine the reset state of the ROMON bit in the MISC register. At the rising edge of RESET, the state of the PK7 pin is latched to the ROMON bit. There is an active pull-up on this pin while in reset and immediately out of reset. The pullup can be turned off by clearing PUPKE in the PUCR register. Refer to the HCS12 MEBI Block Guide for further details. PK7 is not available in the 80 pin package version. 2.3.17 PK6 / XCS — Port K I/O Pin 6 PK6 is a general purpose input or output pin. During MCU expanded modes of operation, when the EMK bit in the MODE register is set to 1, this pin is used as an external chip select signal for most external accesses that are not selected by ECS. There is an active pull-up on this pin while in reset and immediately out of reset. The pullup can be turned off by clearing PUPKE in the PUCR register. Refer to the HCS12 MEBI Block Guide for further details. PK6 is not available in the 80 pin package version. 2.3.18 PK[5:0] / XADDR[19:14] — Port K I/O Pins [5:0] PK[5:0] are general purpose input or output pins. In MCU expanded modes of operation, when the EMK bit in the MODE register is set to 1, PK[5:0] provide the expanded address XADDR[19:14] for the external bus.

Bypass requirements depend on how heavily the MCU pins are loaded. 2.4.2 VDDR, VSSR — Power Supply Pins for I/O Drivers & for Internal Voltage Regulator External power and ground for I/O drivers and input to the internal voltage regulator. Bypass requirements depend on how heavily the MCU pins are loaded. 2.4.3 VDD1, VDD2, VSS1, VSS2 — Power Supply Pins for Internal Logic Power is supplied to the MCU through VDD and VSS. This 2.5V supply is derived from the internal voltage regulator. There is no static load on those pins allowed.

These also allow an external source to supply the core VDD/VSS voltages and bypass the internal voltage regulator. External power and ground, supply to internal voltage regulator. To disable voltage regulator attach VDDR to VSSR. External power and ground, supply to pin drivers. Operating voltage and ground for the analog-to-digital converter, the reference for the internal voltage regulator and the digital-to-analog converters, allows the supply voltage to the A/D to be bypassed independently. Reference voltage high for the ATD converter, and DAC. Reference voltage low for the ATD converter. Provides operating voltage and ground for the Phased-Locked Loop. This allows the supply voltage to the PLL to be bypassed independently. Internal power and ground generated by internal regulator. All VSS pins must be connected together in the application. Because fast signal transitions place high, short-duration current demands on the power supply, use bypass capacitors with high-frequency characteristics and place them as close to the MCU as possible. Bypass requirements depend on MCU pin load. Device User Guide — 9S12E128DGV1/D V01.04 Section 3 System Clock Description The Clock and Reset Generator provides the internal clock signals for the core and all peripheral modules.

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. 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.

This feature allows: • Protection of the contents of FLASH, • Operation in single-chip mode, • Operation from external memory with internal FLASH 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. 4.3.1 Securing the Microcontroller Once the user has programmed the FLASH, 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 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 will be disabled. BDM operations will be blocked. 4.3.3 Unsecuring the Microcontroller In order to unsecure the microcontroller, the internal FLASH must be erased. This can be done through an external program in expanded mode. Once the user has erased the FLASH, the part can be reset into special single chip mode. This invokes a program that verifies the erasure of the internal FLASH. 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 93 Device User Guide — 9S12E128DGV1/D V01.04 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 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 (CRG) Block Guide. 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. 94 Device User Guide — 9S12E128DGV1/D V01.04 Section 5 Resets and Interrupts 5.1 Overview Consult the Exception Processing section of the CPU12 Reference Manual for information on resets and interrupts.

The "S12 LRAE" is a generic Load RAM and Execute (LRAE) program which will be programmed into the flash memory of this device during manufacture. This LRAE program will provide greater programming flexibility to the end users by allowing the device to be programmed directly using SCI after it is assembled on the PCB. Use of the LRAE program is at the discretion of the end user and, if not required, it must simply be erased prior to flash programming. For more details of the S12 LRAE and its implementation, please see the S12 LREA Application Note (AN2546/D) . It is planned that most HC9S12 devices manufactured after Q1 of 2004 will be shipped with the S12 LRAE programmed in the Flash . Exact details of the changeover (ie blank to programmed) for each product will be communicated in advance via GPCN and will be traceable by the customer via datecode marking on the device. Please contact Motorola SPS Sales if you have any additional questions. Section 11 IIC Block Description Consult the IIC Block Guide for information about the IIC Module.

VDD1 and VDD2 are connected together internally. VSS1 and VSS2 are connected together internally. This allows systems to employ better supply routing and further decoupling. Section 20 Printed Circuit Board Layout Proposals The Printed Circuit Board (PCB) must be carefully laid out to ensure proper operation of the voltage regulator as well as the MCU itself. The following rules must be observed: • 100 Every supply pair must be decoupled by a ceramic capacitor connected as near as possible to the corresponding pins (C1 - C6). Device User Guide — 9S12E128DGV1/D V01.04 • 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.

Values cannot be guaranteed by Motorola and are subject to change without notice. NOTE: The part is specified and tested over the 5V and 3.3V ranges. For the intermediate range, generally the electrical specifications for the 3.3V range apply, but the part is not tested in production test in the intermediate range. This supplement contains the most accurate electrical information for the MC9S12E-Family microcontroller available at the time of publication. The information should be considered PRELIMINARY and is subject to change. 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. NOTE: This classification will be added at a later release of the specification 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 MC9S12E-Family utilizes several pins to supply power to the I/O ports, A/D converter, oscillator, PLL and internal logic. The VDDA, VSSA pair supplies the A/D converter and D/A converter. The VDDX, VSSX pair supplies the I/O pins The VDDR, VSSR pair supplies the internal voltage regulator. VDD1, VSS1, VDD2 and VSS2 are the supply pins for the internal logic. VDDPLL, VSSPLL supply the oscillator and the PLL. 105 Device User Guide — 9S12E128DGV1/D V01.04 VSS1 and VSS2 are internally connected by metal. VDD1 and VDD2 are internally connected by metal. VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for ESD protection. 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 3.3V/5V I/O pins Those I/O pins have a nominal level of 3.3V or 5V depending on the application operating point. This group 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. A.1.3.2 Analog Reference This group of pins is comprised of the 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.1.4 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. 106 Device User Guide — 9S12E128DGV1/D V01.04 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).

The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The absolute maximum ratings apply when the device is powered from an external source. 2. All digital I/O pins are internally clamped to VSSX and VDDX, VSSR and VDDR or VSSA and VDDA. 3. These pins are internally clamped to VSSPLL and VDDPLL 4. This pin is clamped low to VSSR, but not clamped high. This pin must be tied low in applications. 107 Device User Guide — 9S12E128DGV1/D V01.04 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 device will be defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot temperature, unless specified otherwise in the device specification.

The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The given operating range applies when this regulator is disabled and the device is powered from an external source. 2. Some blocks e.g. ATD (conversion) and NVMs (program/erase) require higher bus frequencies for proper operation. A.1.8 Power Dissipation and Thermal Characteristics Power dissipation and thermal characteristics are closely related. The user must assure that the maximum operating junction temperature is not exceeded. The average chip-junction temperature (TJ) in °C can be obtained from: T J = T A + ( P D • Θ JA ) T J = Junction Temperature, [°C ] T A = Ambient Temperature, [°C ] P D = Total Chip Power Dissipation, [W] Θ JA = Package Thermal Resistance, [°C/W] The total power dissipation can be calculated from: P D = P INT + P IO P INT = Chip Internal Power Dissipation, [W] Two cases with internal voltage regulator enabled and disabled must be considered: 109 Device User Guide — 9S12E128DGV1/D V01.04 1.

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. 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.

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. B.4.1.2 LVR The release level VLVRR and the assert level VLVRA are derived from the VDD Supply. They are also valid if the device is powered externally. After releasing the LVR 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. B.4.1.3 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. 121 Device User Guide — 9S12E128DGV1/D V01.04 B.4.1.4 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. B.4.1.5 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. B.4.1.6 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. 122 Device User Guide — 9S12E128DGV1/D V01.04 B.4.2 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. Pierce oscillator/external clock mode allows 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.

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 B-3. NOTE: This section is under construction The basic functionality of the PLL is shown in Figure B-2.

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 program and erase operations are timed using a clock derived from the oscillator using the FCLKDIV register. The frequency of this clock must be set within the limits specified as fNVMOP. The minimum program and erase times shown in Table B-5 are calculated for maximum fNVMOP and maximum fbus. The maximum times are calculated for minimum fNVMOP and a fbus of 2MHz. B.5.1.1 Single Word Programming The programming time for single word programming is dependent on the bus frequency as a well as on the frequency f¨NVMOP and can be calculated according to the following formula. 1 1 t swpgm = 9 ⋅ --------------------- + 25 ⋅ ---------f bus f NVMOP B.5.1.2 Row Programming Flash programming where up to 32 words in a row can be programmed consecutively by keeping the command pipeline filled. The time to program a consecutive word can be calculated as: 1 1 t bwpgm = 4 ⋅ --------------------- + 9 ⋅ ---------f bus f NVMOP The time to program a whole row is: t brpgm = t swpgm + 31 ⋅ t bwpgm Row programming is more than 2 times faster than single word programming.

B.5.1.5 Blank Check The time it takes to perform a blank check on the Flash 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. t check ≈ location ⋅ t cyc + 10 ⋅ t cyc Table B-5 NVM Timing Characteristics Conditions are shown in Table A-4 unless otherwise noted Num C 1 D 2 Rating Symbol Min Typ Max Unit External Oscillator Clock fNVMOSC 0.5 501 MHz D Bus frequency for Programming or Erase Operations fNVMBUS 1 3 D Operating Frequency fNVMOP 150 200 kHz 4 P Single Word Programming Time tswpgm 462 74.53 µs 5 D Flash Burst Programming consecutive word tbwpgm 20.42 313 µs 6 D Flash Burst Programming Time for 32 Words tbrpgm 678.42 1035.53 µs 7 P Sector Erase Time tera 204 26.73 ms 8 P Mass Erase Time tmass 1004 1333 ms 9 D Blank Check Time Flash per block t check 115 327786 tcyc MHz NOTES: 1.
