Notes on CPU Rewrite Mode
Take the notes described below when rewriting the flash memory in
CPU rewrite mode.
qOperation speed
During CPU rewrite mode, set the system clock
φ to 4.0 MHz or less
using the main clock division ratio selection bits (bits 4 and 5 of ad-
dress 003B16).
qInstructions inhibited against use
The instructions which refer to the internal data of the flash memory
cannot be used during CPU rewrite mode.
qInterrupts inhibited against use
The interrupts cannot be used during CPU rewrite mode because
they refer to the internal data of the flash memory.
qWatchdog timer
If the watchdog timer has been already activated, internal reset due
to an underflow will not occur because the watchdog timer is surely
cleared during program or erase.
qReset
Reset is always valid. The MCU is activated using the boot mode at
release of reset in the condition of CNVss = “H”, so that the program
will begin at the address which is stored in addresses FFFC16 and
FFFD16 of the boot ROM area.
