Notes on CPU Rewrite Mode
The below notes applies when rewriting the flash memory in CPU
rewrite mode.
G
Operation speed
During CPU rewrite mode, set the internal clock
φ
to 6 MHz or less
using the X
IN
Divider Select Bit (bit 7 of address 001F
16
).
G
Instructions inhibited against use
The instructions which refer to the internal data of the flash
memory cannot be used during CPU rewrite mode .
G
Interrupts inhibited against use
The interrupts cannot be used during CPU rewrite mode because
they refer to the internal data of the flash memory.
G
Reset
Reset is always valid. If reset is performed on erasing, 5 ms is
needed until the flash memory will return to its normal state. Ac-
cordingly, wait at least 5 ms before releasing reset.
