Write 0 before writing 1 when setting the FMR01, FMR02, or FMR11 bit to 1. Do not generate an interrupt
between writing 0 and 1.
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.
To perform programming and erasure, use VCC = 2.7 to 5.5 V as the supply voltage. Do not perform
programming and erasure at less than 2.7 V.
