Note on the FMSTP bit
Do not set the FMR27 bit to 1 while the FMSTP bit is 1 (flash memory stops). Also, do not set the FMR27 bit to 1 when the
flash memory status is busy (the FST7 bit is 0) immediately after changing the FMSTP bit from 1 to 0 (flash memory
operates).
Note on CPU rewrite mode
Do not execute the program command, block erase command, or lock bit program command while the FMR27 bit is 1.
Note on the A/D converter
Do not perform A/D conversion while the FMR27 bit is 1. Also, do not set the FMR27 bit to 1 while the ADST bit is 1
(during A/D conversion).
