To set one of the following bits to 1, first write 0 and then 1 immediately. Do not generate an interrupt between
writing 0 and writing 1.

To set one of the following bits to 0, first write 1 and then 0 immediately. Do not generate an interrupt between
writing 1 and writing 0.
•
In EW0 Mode, if the supply voltage drops while rewriting any block in which a rewrite control program is
stored, it may not be possible to rewrite the flash memory because the rewrite control program cannot be
rewritten correctly. In this case, use standard serial I/O mode.
Do not write additions to the already programmed address.
Do not enter stop mode or wait mode during erase-suspend.
When the FST7 in the FST register is set to 0 (busy (during programming or erasure execution), do not enter to
stop mode or wait mode.
To perform programming and erasure, use VCC = 2.7 V to 5.5 V as the supply voltage. Do not perform
programming and erasure at less than 2.7 V.
Do not execute the block blank check command during erase-suspend.
