Note:
In CPU rewrite mode, the flash memory can be rewritten when the CPU executes software commands.
Program ROM 1, program ROM 2, and data flash can be rewritten with the MCU mounted on the board
and without using a ROM programmer.
The program and block erase commands are executed only in individual block areas of program ROM 1,
program ROM 2, and data flash.
Erase-write 0 mode (EW0 mode) and erase-write 1 mode (EW1 mode) are available in CPU rewrite
mode. Table 30.10 lists the differences between EW0 mode and EW1 mode.

CPU Rewrite Mode
Item
Do not generate an interrupt (except NMI interrupt) or start a DMA transfer.
EW0 Mode and EW1 Mode
The rewrite control program must be
transferred to an area other than the
flash memory (e.g., RAM) before being
executed.
