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.
The FMR01 or FMR02 bit in the FMR0 register
The FMR13 bit in the FMR1 register
The FMR20, FMR22, or FMR 27 bit in the FMR2 register
The FMR14, FMR15, FMR16, or FMR17 bit in the FMR1 register
