NOTES:
1. 2. 3. 4.
Relationship between system clock frequency and power source voltage is shown in the graph below. When the A/D converter is used, refer to the recommended operating conditions of the A/D converter. 12.5 MHz < f(XIN) 16 MHz is not available in the frequency/2 mode. The oscillation start voltage and the oscillation start time differ depending on factors such as the oscillator, circuit constants, and operating temperature range. Note that oscillation start may be particularly difficult at low voltage when using a high-frequency oscillator. 5. When using the microcomputer in low-speed mode, set the clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.

APPENDIX Note on Programming 1. Processor Status Register (1) Initialization of the processor status register It is required to initialize the processor status register (PS) flags which affect program execution. It is particularly essential to initialize the T and D flags because of their effect on calculations. Initialize these flags at the beginning of the program. At a reset, the contents of the processor status register (PS) are undefined except for the I flag which is "1". 2. Decimal Calculations (1) Instructions for decimal calculations To perform decimal calculations, set the decimal mode (D) flag to "1" with the SED instruction and execute the ADC or SBC instruction. In that case, after the ADC or SBC instruction, execute another instruction before the SEC, CLC, or CLD instruction.
Set the decimal mode (D) flag to "1"
Execute the ADC or SBC instruction
Reset
NOP
Initialize the flags
Execute the SEC, CLC, or CLD instruction
Main program
Fig. 100 Instructions for decimal calculations
(2) Status flag at decimal calculations When the ADC or SBC instruction is executed in decimal mode (D flag = "1"), three of the status flags (N, V, and Z) are disabled. The carry (C) flag is set to "1" if a carry is generated and is cleared to "0" if a borrow is generated as a result of a calculation, so it can be used to determine whether the calculation has generated a carry or borrow. Initialize the C flag before each calculation.
Fig. 98 Initialization of processor status register flags
(2) How to refer the processor status register To refer the contents of the processor status register (PS), execute the PHP instruction once and then read the contents of (S+1). If necessary, execute the PLP instruction to return the stored PS to its original status.
(S) (S) + 1 Stored PS

3. JMP Instruction When using the JMP instruction (indirect addressing mode), do not specify the address where "FF16" is allocated to the loworder 8 bits as the operand. 4. Multiplication and Division Instructions (1) The MUL and DIV instructions are not affected by the T and D flags. (2) Executing these instructions does not change the contents of the processor status register. 5. Read-Modify-Write Instruction Do not execute any read-modify-write instruction to the read invalid (address) SFR. The read-modify-write instruction reads 1-byte of data from memory, modifies the data, and writes 1-byte the data to the original memory. In the 740 Family, the read-modify-write instructions are the following: (1) Bit handling instructions: CLB, SEB (2) Shift and rotate instructions: ASL, LSR, ROL, ROR, RRF (3) Add and subtract instructions: DEC, INC (4) Logical operation instructions (1's complement): COM Although not the read-modify-write instructions, add and subtract/logical operation instructions (ADC, SBC, AND, EOR, and ORA) when T flag = "1" operate in the way as the readmodify-write instruction. Do not execute them to the read invalid SFR. When the read-modify-write instruction is executed to the read invalid SFR, the following may result: As reading is invalid, the read value is undefined. The instruction modifies this undefined value and writes it back, so the written value will be indeterminate. Notes on Peripheral Functions Notes on I/O Ports 1. Use in Stand-By State When using the MCU in stand-by state* 1 for low-power consumption, do not leave the input level of an I/O port undefined. Be especially careful to the I/O ports for the Nchannel open-drain. In this case, pull-up (connect to Vcc) or pull-down (connect to Vss) these ports through a resistor. When determining a resistance value, note the following: * External circuit * Variation in the output level during ordinary operation When using a built-in pull-up resistor, note variations in current values: * When setting as an input port: Fix the input level * When setting as an output port: Prevent current from flowing out externally. Even if a port is set to output by the direction register, when the content of the port latch is "1", the transistor becomes the OFF state, which allows the port to be in the high-impedance state. This may cause the level to be undefined depending on external circuits. As described above, if the input level of an I/O port is left undefined, the power source current may flow because the potential applied to the input buffer in the MCU will be unstable. *1 Stand-by state: Stop mode by executing the STP instruction Wait mode by executing the WIT instruction 2. Modifying Output Data with Bit Handling Instruction When the port latch of an I/O port is modified with the bit handling instruction* 1 , the value of an unspecified bit may change. I/O ports can be set to input mode or output mode in byte units. When the port register is read or written, the following will be operated: * Port as input mode Read: Read the pin level Write: Write to the port latch * Port as output mode Read: Read the port latch or peripheral function output (specifications vary depending on the port) Write: Write to the port latch (output the content of the port latch from the pin) Meanwhile, the bit handling instructions are the read-modifywrite instructions*2. Executing the bit handling instruction to the port register allows reading and writing a bit unspecified with the instruction at the same time. If an unspecified bit is set to input mode, the pin level is read and the value is written to the port latch. At this time, if the original content of the port latch and the pin level do not match, the content of the port latch changes. If an unspecified bit is set to output mode, the port latch is normally read, but the peripheral function output is read in some ports and the value is written to the port latch. At this time, if the original content of the port latch and the peripheral function output do not match, the content of the port latch changes. *1 Bit handling instructions: CLB, SEB *2 Read-modify-write instruction: Reads 1-byte of data from memory, modifies the data, and writes 1-byte of the data to the original memory.

3. Direction Registers The values of the port direction registers cannot be read. This means, it is impossible to use the LDA instruction, memory operation instruction when the T flag is "1", addressing mode using direction register values as qualifiers, and bit test instructions such as BBC and BBS. It is also impossible to use bit operation instructions such as CLB and SEB, and read-modifywrite instructions to direction registers, including calculations such as ROR. To set the direction registers, use instructions such as LDM or STA. 4. Pull-Up Control Only for the pin set to input mode, pull-up is controlled by the PULL register and the segment output disable register. Notes on Termination of Unused Pins 1. Termination of Unused Pins Perform the following at the shortest possible distance (20 mm or less) from the MCU pins. (1) I/O ports Set the ports to input mode and connect each pin to VCC or VSS through a resistor of 1 k to 10 k. An internal pull-up resistor can also be used for the port where the internal pull-up resister is selectable. To set the ports to output mode, leave open at "L" or "H" output. * When setting the ports to output mode and leave open, input mode in the initial state remains until the mode of the ports are switched to output mode by a program after a reset. This may cause the voltage level of the pins to be undefined and the power source current to increase while the ports remains in input mode. For any effects on the system, careful system evaluations should be implemented on the user side. * The direction registers may be changed due to a program runaway or noise, so reset the registers periodically by a program to increase the program reliability. 2. Termination Concerns (1) When setting I/O ports to input mode [1] Do not leave open * The power source current may increase depending on the first-stage circuit. * The ports are more likely affected by noise when compared with the termination shown on the above "1. (1) I/O ports" [2] Do not connect to VCC or VSS directly If the direction registers are changed to output mode due to a program runaway or noise, a short circuit may occur. [3] Do not connect multiple ports in a lump to VCC or VSS through a resistor. If the direction registers are changed to output mode due to a program runaway or noise, a short circuit may occur between the ports.

Notes on Timers 1. Frequency Divider All timers shares one circuit for the frequency divider to generate the count source. Thus the frequency divider is not initialized when each individual timer is activated. When the frequency divider is selected as the count source, a one-cycle delay of the maximum count source will result between when the timer is activated and when it starts counting or outputs the waveform. The count source cannot be observed externally. 2. Division Ratio for Timer 1 to 4 The division ratio is 1/(n+1) when the value n (0 to 255) is written to the timer latch. 3. Switching Frequency and Count Source for Timer 1 to 4, X, and Y Switch the frequency division or count source* while the timer count is stopped. *This also applies when the frequency divider output is selected as the timer count source and the count source is switched in conjunction with a transition between operating modes (onchip oscillator mode, XIN mode, or low-speed mode). Be careful when changing settings in the CPU mode register. 4. Setting Timer 1 and 2 When STP Instruction Executed Before executing the STP instruction, first set the wait time at return. 5. Setting Order to Timer 1 to 4 When switching the count source of timer 1 to timer 4, a narrow pulse may be generated at the count input, which causes the timer count value to be undefined. Also, if the timers are used in cascade connection, a narrow pulse may be generated at the output when writing to the pervious timer, which causes the next timer count value to be undefined. Thus set the value from timer 1 in order after setting the count source of timer 1 to timer 4. 6. Write to Timer 2, 3, and 4 When writing to the latch only, if the write timing to the reload latch and the underflow timing are almost the same, the value is set into the timer and the timer latch at the same time. At this time, count is stopped during write operation to the reload latch. 7. Timer 3 PWM0 Mode, Timer 4 PWM1 Mode (1) When PWM output is suspended once it starts, the time to resume outputting may be delayed one section (256 x ts) of the short interval depending on the level of the output pulse at that time: Stop at "H": No output delay Stop at "L": Output is delayed time of 256 x ts (2) When PWM mode is used, the interrupt requests and values of timer 3 and timer 4 are updated every cycle of the long interval (4 x 256 x ts). 8. Write Order to Timer X (1) When timer mode, pulse output mode, event counter mode, or pulse width measurement mode is set, write to the following registers in the order below: The timer X register (extension) The timer X register (low-order) The timer X register (high-order) Writing to only one of these registers cannot be performed. When either of the above modes is set and timer X operates as a 16-bit counter, if the timer X register (extension) is never set after a reset release, setting the timer X register (extension) is not required. In that case, write the timer X register (low-order) first and the timer X register (high-order) next. However, once the timer X register (extension) is written, note that the value is retained in the reload latch. (2) Write to the timer X register by the 16-bit unit. Do not read the timer X register while write operation is performed. If the write operation is not completed, normal operation will not be performed. (3) When IGBT output mode or PWM mode is set, do not write "1" to the timer X register (extension). If "1" has been already written to the timer X register, be sure to write "0" to the register before use. Write to the following registers in the order below: The compare registers 1, 2, 3 (high- and low-order) The timer X register (extension) The timer X register (low-order) The timer X register (high-order) The compare registers (high- and low-order) can be written in either order. However, be sure to write both the compare registers 1, 2, 3 and the timer X register at the same time. 9. Read Order to Timer X (1) In all modes, read the following registers in the order below: The timer X register (extension) The timer X register (high-order) The timer X register (low-order) When reading the timer X register (extension) is not required, read the timer X register (high-order) first and the timer X register (low-order) next. The read order to the compare registers 1, 2, 3 is not specified. (2) Read the timer X register in 16-bit units. Do not write to it during read operation. If read operation is terminated in progress, normal operation will not be performed.

10. Write to Timer X (1) Timer X can select either writing data to both the latch and the timer at the same time or writing data only by the timer X write control bit (b3) in the timer X mode register (address 002D16). When writing to the latch only, if a value is written to the timer X address, the value is set into the reload latch and the timer is updated at the next underflow. After a reset release, if a value is written to the timer X address, the value is set into the timer and the timer latch at the same time, because they are written simultaneously. When writing to the latch only, if the write timing to the high-order reload latch and the underflow timing are almost the same, the value is set into the timer and the timer latch at the same time. At this time, count is stopped during write operation to the high-order reload latch. (2) Switch the frequency division or count source* while the timer count is stopped. *This also applies when the frequency divider output is selected as the timer count source and the count source is switched in conjunction with a transition between operating modes (onchip oscillator mode, XIN mode, or low-speed mode). Be careful when changing settings in the CPU mode register. 11. Setting Timer X Mode Register When PWM mode or IGBT output mode is set, be sure to set the write control bit in the timer X mode register to "1" (writing to latch only). After writing to the timer X register (high-order), the contents of both registers are simultaneously reflected in the output waveform at the next underflow. 12. Timer X Output Control Functions To use the output control functions (INT1 and INT2), set the levels of INT1 and INT2 to "H" for the falling edge active or to "L" for the rising edge active before switching to IGBT output mode. 13. CNTR0 Active Edge Selection (1) Setting the CNTR0 active edge switch bits also affects the interrupt active edge at the same time. (2) When the pulse width is measured, set bit 7 of the CNTR0 active edge switch bits to "0". 14. When Timer X Pulse Width Measurement Mode Used When timer X pulse mode measurement mode is used, enable the event counter wind control data (bit 5 of timer X mode register (address 002D16)) by setting to "0". If the event counter window control data (bit 5 of timer X mode r egister (address 002 D16)) is set to "1 " (disabled) to enable/disable the CNTR0 input, the input is not accepted after the timer 1 underflow. 15. CNTR1 Active Edge Selection Setting the CNTR1 active edge switch bits also affects the interrupt active edge at the same time. However, in pulse width HL continuous HL measurement mode, the CNTR1 interrupt request is generated at both rising and falling edges of the pin regardless of the settings of the CNTR1 active edge switch bits. 16. Read from/Write to Timer Y (1) When reading from/writing to timer Y, read from/write to both the high-order and low-order bytes of timer Y. To read the value, read the high-order bytes first and the low-order bytes next. To write the value, write the low-order bytes first and the high-order bytes next. Writing/reading should be preformed in 16-bit units. If write/read operation is changed in progress, normal operation will not be performed. (2) Timer Y can select either writing data to both the latch and the timer at the same time or writing data only by the timer Y write control bit (b0) in the timer Y control register (address 003916). When writing to the latch only, if a value is written to the timer Y address, the value is set into the reload latch and the timer is updated at the next underflow. After a reset release, if a value is written to the timer Y address, the value is set into the timer and the timer latch at the same time, because they are written simultaneously. When writing to the latch only, if the write timing to the high-order reload latch and the underflow timing are almost the same, the value is set into the timer and the timer latch at the same time. At this time, count is stopped during write operation to the high-order reload latch. (3) Switch the frequency division or count source* while the timer count is stopped. *This also applies when the frequency divider output is selected as the timer count source and the count source is switched in conjunction with a transition between operating modes (onchip oscillator mode, XIN mode, or low-speed mode). Be careful when changing settings in the CPU mode register. 17. Real time port control When switching the setting of the real time port control bits between valid and invalid, write to the timer Y mode register in byte units with the LDM or STA instruction so that both bits are switched at the same time. Also, before using this function, set the P46 and P47 port direction registers to output.

Notes on Serial I/O1 Becaouse the operation of the serial I/O2 is as same as serial I/O1, the following notes are written about the serial I/O1. 1. Write to Baud Rate Generator Write to the baud rate generator while transmission/reception is stopped. 2. Setting Sequence When Serial I/O1 Transmit Interrupt Used To use the serial I/O1 transmit interrupt, if the interrupt occurrence synchronized with settings is not required, take the following sequence: (1) Set the serial I/O1 transmit interrupt enable bit (bit 2 of interrupt control register 2 (address 003F16)) to "0" (disabled). (2) Set the transmit enable bit to "1". (3) After one or more instructions have been executed, set the serial I/O1 transmit interrupt request bit (bit 2 of interrupt request register 2 (address 003D16)) to "0" (no interrupt). (4) Set the serial I/O1 transmit interrupt enable bit to "1" (enabled). When the transmit enable bit is set to "1", the transmit buffer empty flag (bit 0 of serial I/O1 status register) and the transmit shift completion flag are set to "1". This allows an interrupt request to be generated regardless of which interrupt occurrence source has been selected by the transmit interrupt source selection bit (bit 3 of serial I/O1 control register) and the serial I/O1 transmit interrupt request bit is set to "1". 3. Data Transmission Control Using Transmit Shift Completion Flag After transmit data is written to the transmit buffer register, the transmit shift completion flag (bit 2 of serial I/O1 status register (address 001916)) changes from "1" to "0" after a delay of 0.5 to 1.5 cycles of the system clock. Thus, after transmit data is written to the transmit buffer register, note this delay when controlling data transmission by referencing the transmit shift completion flag. 4. Setting Serial I/O1 Control Register Before setting the serial I/O1 control register again, first set both the transmit enable bit and the receive enable bit to "0" and initialize the transmission and reception circuits. 6. Serial I/O1 Enable Bit during Transmit Operation During transmission, if the serial I/O1 enable bit (bit 7 of serial I/O1 control register (address 001A16)) is set to "0", the pin function is set to an I/O port and the internal transmit operation continues even though transmit data is not output externally. Also, if the transmit buffer register is written in this state, transmit operation starts internally. If the serial I/O1 enable bit is set to "1" at this time, transmit data is output to the TxD pin from that point. 7. Transmission Control When External Clock Selected During data transmission, if the external clock is selected as the synchronous clock, set the transmit enable bit to "1" while SCLK1 is set to "H". Also, write to the transmit buffer register while SCLK1 is set to "H". 8. Receive Operation in Clock Synchronous Serial I/O Mode During reception in clock synchronous serial I/O mode, set both the transmit enable bit and the receive enable bit to "1". Then write dummy data to the transmit buffer register. When the internal clock is selected as the synchronous clock, the synchronous clock is output at this point and receive operation starts. When the external clock is selected, reception is enabled at this point and inputting the external clock starts transmit operation. The P55/TXD1 [P32/TxD2] pin outputs dummy data written in the transmit buffer register. 9. Transmit/Receive Operation in Clock Synchronous Serial I/O Mode In clock synchronous serial I/O mode, set the transmit enable bit and the receive enable bit to "0" simultaneously to stop transmit/receive operations. If only one of the operations is stopped, transmission and reception cannot be synchronized, which will cause a bit error.
Set both the transmit enable bit (TE) and the receive enable bit (RE) to "0" Set bits 0 to 3, and 6 of the serial I/O1 control register. Set both the transmit enable bit (TE) and the receive enable bit (RE), or one of them to "1".
Settings can be made with the LDM instruction at the same time
Fig. 103 Sequence of setting serial I/O1 control register
5. Pin Status After Transmission Completed After transmission is completed, the TxD pin retains the level when transmission is completed. When the internal clock is selected in clock synchronous serial I/O mode, the SCLK1 pin is set to "H".

Notes on A/D Conversion 1. Analog Input Pin Set the signal source impedance for analog input low, or equip an analog input pin with an external capacitor of 0.01 F to 1 F. In addition, operations of application products should be verified thoroughly on the user side. An analog input pin has a built-in capacitor for analog voltage comparison. Thus if a signal from the high impedance signal source is input to the analog input pin, charge and discharge noise will be generated. This may cause the A/D conversion/comparison accuracy to drop. 2. Clock Frequency during A/D Conversion The comparator input consists of a capacity coupling. If the conversion rate is too low, the A/D conversion accuracy may deteriorate due to a charge lost, so set f(XIN) 500 kHz or more for A/D conversion in XIN mode. Also, do not execute the STP or WIT instruction during A/D conversion. In low-speed mode (when on-chip oscillator is selected), as A/D conversion is performed using the internal on-chip oscillator, there is no limit on the minimum frequency for f(XIN). 3. ADKEY Function When the ADKEY enable bit is set to "1", the analog input pin selection bits are disabled. Do not execute the A/D conversion by a program while ADKEY is enabled. Enabling ADKEY does not change bits 0 to 2 of ADCON. 4. A/D Conversion Immediately After ADKEY Function Started In the ADKEY function, A/D conversion is not performed to the analog input voltage immediately after starting the function. This causes the A/D conversion result immediately after starting the function to be undefined. If the A/D conversion result of the analog input voltage applied to the ADKEY pin is required, select the analog input pin corresponding to ADKEY before performing A/D conversion. 5. Input Voltage Applied to ADKEY Pin Set the input to the ADKEY pin into a steep falling waveform and stabilize the input voltage within eight cycles (1 s when f(XIN) = 8 MHz) from the moment the input voltage reaches VIL or lower. The actual threshold voltage for the ADKEY pin is between VIH and VIL. To prevent unnecessary ADKEY operation due to noise or other factors, set the ADKEY pin voltage to VIH (0.9 VCC) or more while the input is waited. 6. Register Operation during A/D Conversion The A/D conversion operation is not guaranteed if the following are preformed: * The CPU mode register is operated during A/D conversion operation * The AD control register is operated during A/D conversion operation * The STP or WIT instruction is executed during A/D conversion operation 7. A/D Converter Power Source Pin Connect to the A/D converter power source pin to AVSS or VSS whether the A/D conversion function is used or not. If the AVSS pin is left open, the MCU may operate incorrectly because the pin will be affected by noise or other factors.

2. Executing STP Instruction Execution of the STP instruction sets the LCD enable bit (bit 3 of the LCD mode register) and bits 0 to 5 and bit 7 of the LCD power control register to "0" and the LCD panel turns off. To make the LCD panel turn on after returning from the stop mode, set these bits to "1". 3. VL3 Pin To use the LCD drive control circuit while VL3 is set to the voltage equal to VCC, apply the VCC voltage to the VL3 pin and write "1" to the VL3 connection bit of LCD power control register (address 003816)). 4. LCD Drive Power Supply Power supply capacitor may be insufficient with the division resistance for LCD power supply, and the characteristic of the LCD panel. In this case, there is the method of connecting the bypass capacitor about 0.1-0.33F to VL1-VL3 pins. The example of a strengthening measure of the LCD drive power supply is shown below. 5. Using No ROM Correction Function If the ROM correction function is not used, the ROM correction vector can be used as normal RAM/ROM. When using as normal RAM/ROM, be sure to set bits 1 and 0 of the ROM correction enable register to "0" (disabled). Notes on Clock Generating Circuit 1. Oscillation Circuit Constants The oscillation circuit constants vary depending on the resonator. Use values recommended by the oscillator manufacturer. A feed-back resistor is implemented between the XIN and XOUT pins (an external feed-back resistor may be required depending on conditions). As no feed-back resistor is implemented between XCIN and XCOUT, add a feedback resistor of about 10 M. 2. Transition between Modes When the MCU transits between on-chip oscillator mode, XIN mode, or low-speed mode, both the XIN and XCIN oscillations must be stabilized. Be especially careful when turning the power on and returning from stop mode. Refer to the clock state transition diagram for a transition between each mode. Also, set the frequency in the condition that f(XIN) 3 x (XCIN). When XIN mode is not used (the XIN-XOUT oscillation or external clock input to XIN is not performed), connect XIN to VCC through a resistor. 3. Oscillation Stabilization Before executing the STP instruction, set the values * to generate the wait time required for oscillation stabilization to timer 1 latch and timer 2 latch (low-order 8 bits of timer 1 and high-order 8 bits of timer 2). *Referential values (Set values according to your oscillator and system) * OSCSEL = "L" in the flash memory and QzROM versions: ..................................................................... 000516 or more * OSCSEL = "H" in the QzROM version: .....................................................................01FF16 or more 4. Low-Speed Mode, XIN Mode To use low-speed mode or XIN mode, wait until oscillation stabilizes after enabling the XIN-XOUT and XCIN-XCOUT oscillation, then switch to the mode.

Notes on ROM Correction Function 1. Returning to Main Program To return to the main program from the correction program, use the JMP instruction (3-byte instruction). 2. Using ROM Correction Function If the ROM correction function is used, be sure to enable the ROM correction enable bit after setting the ROM correction register. 3. Address Do not set addresses other than the ROM area in the ROM correction address registers. Also, do not set the same address in the ROM correction address 1 register and the ROM correction address 2 register. 4. ROM Correction Process Include the ROM correction process in the program beforehand.

Notes on Flash Memory Mode
* CPU Rewrite Mode
(1) Operating Speed During CPU rewrite mode, set the system clock to 4.0 MHz or less using the main clock division ratio selection bits (bits 6 and 7 of address 003B16). (2) Prohibited Instructions During CPU rewrite mode, the instructions which reference data in the flash memory cannot be used. (3) Interrupts During CPU rewrite mode, interrupts cannot be used because they reference data in the flash memory. (4) Watchdog Timer If the watchdog timer has been running already, the internal reset by underflow will not occur because the watchdog timer is continuously cleared during program or erase operation. (5) Reset Reset is always valid. If CNVSS = "H" when a reset is released, boot mode is active. The program starts from the address stored in addresses FFFC16 and FFFD16 in boot ROM area. Notes on Watchdog Timer 1. Watchdog Timer Underflow The watchdog timer does not operate in stop mode, but it continues counting during the wait time to release the stop state and in wait mode. Write to the watchdog timer control register so that the watchdog timer will not underflow during these periods. 2. Stopping On-Chip Oscillator Oscillation When the on-chip oscillator is selected by the watchdog timer count source selection bit 2, the on-chip oscillator forcibly oscillates and it cannot be stopped. Also, in this time, set the STP instruction function selection bit to "1" at this time. Select "0" (SOURCE) for the watchdog timer count source selection bit 2 at the system which on-chip oscillator is stopped. 3. Watchdog Timer Control Register Bits 7 to 5 can be rewritten only once after a reset. After writing, rewriting is disabled because they are locked. These bits are set to "0" after a reset.
Notes on Differences between QzROM Version and Flash Memory Version The flash memory and QzROM versions differ in their manufacturing processes, built-in ROM, memory size, and layout patterns. Because of these differences, characteristic values, operation margins, noise immunity, and noise radiation and oscillation circuit constants may vary within the specified range of electrical characteristics. When switching to the QzROM version, implement system evaluations equivalent to those performed in the flash memory version. Confirm page 11 about the differences of functions. Notes on Power Source Voltage When the power supply voltage value of the MCU is less than the value indicated in the recommended operating conditions, the MCU may not operate normally and perform unstable operation. In a system where the power source voltage drops slowly when the power source voltage drops or the power is turned off, reset the MCU when the power source voltage is less than the recommended operating conditions, and design the system so that this unstable operation does not cause errors to it. Notes on Handling Power Source Pins Before using the MCU, connect a capacitor suitable for high frequencies as a bypass capacitor between the following: The power source pin (VCC pin) and the GND pin (VSS pin) The power source pin (VCC pin) and the analog power source input pin (AVSS pin). As a bypass capacitor, a ceramic capacitor of 0.01 F to 0.1 F is recommended. Also, use the shortest possible wiring to connect a bypass capacitor between the power source pin and the GND pin and between the power source pin and the analog power source pin. Notes on Memory 1. RAM The RAM content is undefined at a reset. Be sure to set the initial value before use.

Notes on QzROM Version Wiring to OSCSEL pin (1) OSCSEL = L Connect the OSCSEL pin the shortest possible to the GND pattern which is supplied to the VSS pin of the microcomputer. In addition connecting an approximately 5 k resistor in series to the GND could improve noise immunity. In this case as well as the above mention, connect the pin the shortest possible to the GND pattern which is supplied to the VS S pin of the microcomputer. (2) OSCSEL = H Connect the OSCSEL pin the shortest possible to the VCC pattern which is supplied to the VCC pin of the microcomputer. In addition connecting an approximately 5 k resistor in series to the VCC could improve noise immunity. In this case as well as the above mention, connect the pin the shortest possible to the VC C p a t t e r n w h i c h i s s u p p l i e d t o t h e V C C p i n o f t h e microcomputer. The OSCSEL pin is the power source input pin for the built-in QzROM. When programming in the QzROM, the impedance of the OSCSEL pin is low to allow the electric current for writing to flow into the built-in QzROM. Because of this, noise can enter easily. If noise enters the OSCSEL pin, abnormal instruction codes or data are read from the QzROM, which may cause a program runaway.

QzROM Version Product Shipped in Blank As for the product shipped in blank, Renesas does not perform the writing test to user ROM area after the assembly process though the QzROM writing test is performed enough before the assembly process. Therefore, a writing error of approximate 0.1% may occur. Moreover, please note the contact of cables and foreign bodies on a socket, etc. because a writing environment may cause some writing errors. Ordering QzROM Writing 1. Notes On QzROM Writing Orders When ordering the QzROM product shipped after writing, submit the mask file (extension: .msk) which is made by the mask file converter MM. * Be sure to set the ROM option data* setup when making the mask file by using the mask file converter MM.. The ROM code protect is specified according to the ROM option data* in the mask file which is submitted at ordering. Note that the mask file which has nothing at the ROM option data* or has the data other than "0016", "FE16" and "FF16" can not be accepted. * Set "FF16" to the ROM code protect address in ROM data regardless of the presence or absence of a protect. When data other than "FF16" is set, we may ask that the ROM data be submitted again. * ROM option data: mask option noted in MM 2. Data Required for QzROM Ordering The following are necessary when ordering a QzROM product shipped after writing: * QzROM Writing Confirmation Form* * Mark Specification Form* * ROM data: Mask file * For the QzROM writing confirmation form and the mark specification form, refer to the "Renesas Technology Corp." Homepage (http://www.renesas.com/homepage.jsp). Note that we cannot deal with special font marking (customer's trademark etc.) in QzROM microcomputer.

Overvoltage in QzROM Version Make sure that voltage exceeding the VCC pin voltage is not applied to other pins. In particular, ensure that the state indicated by bold lines in figure below does not occur for pin OSCSEL pin (VPP power source pin for QzROM) during power-on or poweroff. Otherwise the contents of QzROM could be rewritten.

Page 130 of 131
38D2 Group
During CPU rewrite mode, set the system clock 4.0 MHz or less using the main clock division ratio selection bits (bits 6 and 7 of address 003B16). 2. Prohibited Instructions The instructions which refer to the internal data of the flash memory cannot be used during the CPU rewrite mode. 3. Interrupts The interrupts cannot be used during the CPU rewrite mode because they refer to the internal data of the flash memory. 4. Watchdog Timer In case of the watchdog timer has been running already, the internal reset generated by watchdog timer underflow does not happen, because of watchdog timer is always clearing during program or erase operation. 5. Reset Reset is always valid. In case of CNVSS = "H" when reset is released, boot mode is active. So the program starts from the address contained in address FFFC16 and FFFD16 in boot ROM area. CNVSS Pin The CNVSS pin determines the flash memory mode. Connect the CNVSS pin the shortest possible to the GND pattern which is supplied to the VSS pin of the microcomputer. In addition connecting an approximately 5 k. resistor in series to the GND could improve noise immunity. In this case as well as the above mention, connect the pin the shortest possible to the GND pattern which is supplied to the VS S pin of the microcomputer.
Note. When the boot mode or the standard serial I/O mode is used, a switch of the input level to the CNVSS pin is required.
