Prior to entering CPU rewrite mode (EW0, EW1 mode), set the CPU clock frequency to 10 MHz or lower using
bits MCD4 to MCD0 in the MCD register, and also set the PM12 bit in the PM1 register to 1 (1 wait state).
The following instructions cannot be used in EW0 mode because the flash memory is accessed by executing
these instructions: UND, INTO, JMPS, JSRS, and BRK instructions.
To set the FMR01 or FMR02 bit in the FMR0 register, or the FMR11 bit in the FMR1 register to 1, write a 1
immediately after writing a 0 to the bit. Write to the FMR0 or FMR1 register in 8-bit units. Do not generate an
interrupt or a DMA or DMACII transfer between these two settings. Also, set these bits while a high-level
(“H”) signal is applied to the NMI pin.
To change the FMR01 bit from 1 to 0, enter read array mode first, and then write into address 0057h in 16-bit
units. Set the eight high-order bits to 00h.
If the supply voltage drops while rewriting the block where a rewrite control program is stored, it may not be
possible to rewrite the flash memory again, because the rewrite control program is not rewritten successfully. If
this happens, use standard serial I/O mode to rewrite the block.
Do not rewrite a block where the rewrite control program is stored.
To use peripheral function interrupts, place interrupt routine programs and the relocatable vector table in the
RAM area.
When an interrupt request is generated by the NMI, watchdog timer, Vdet4 detection function, or oscillation
stop detection function, registers FMR0 and FMR1 are forcibly initialized and the erase or program operation
in progress is aborted. Now that the flash memory can be accessed, the interrupt routine will be executed.
The address match interrupt is not available because the flash memory is accessed to process this interrupt.
When an interrupt request is generated by the peripheral function or watchdog timer (when the PM22 bit in the
PM2 register is set to 0) during the erase or program operation, the interrupt is acknowledged after the erase or
program operation is completed.
When an interrupt request is generated by the NMI, watchdog timer (when the PM22 bit is set to 1), Vdet4
detection function, or oscillation stop detection function, registers FMR0 and FMR1 are forcibly initialized and
the erase or program operation in progress is aborted. Now that the flash memory can be accessed, the interrupt
routine will be executed.
