Notes:
1. To set this bit to 1, first write 0 and then 1 immediately. Do not generate an interrupt between writing 0 and
2. Write to the FMSTP bit by a program transferred to the RAM. The FMSTP bit is enabled when the FMR01 bit is
3. The CMDRST bit is enabled when the FMR01 bit is set to 1 (CPU rewrite mode enabled) and the FST7 bit in the
4. This bit valid only program ROM area.
5. To set the FMR01 bit to 0 (CPU rewrite mode disabled), set it when the RDYSTI bit in the FST register is set to 0

set to 1 (CPU rewrite mode enabled). To set the FMSTP bit to 1 (flash memory stops), set it when the FST7 bit in
the FST register is set to 1 (ready).
FST register is set to 0 (busy).
(no flash ready status interrupt request) and the BSYAEI bit is set to 0 (no flash access error interrupt request).
The program unit to program ROM area can be selected from 8-bit (byte) units or 16-bit (word) units. When
this bit is set to 1 (word units), use the word command for writing the software command.
When the FMR01 bit is set to 1 (CPU rewrite mode enabled), the MCU is made ready to accept software
commands.
When the FMR02 bit is set to 1 (EW1 mode), EW1 mode is selected.
