23.5.2
Setting the FMCMDEN bit in FLMCR1 to 1 shifts the flash memory into user program mode, in
which commands can be accepted. Figure 23.3 shows how to set and clear the EW0 mode.
Programming and erasure are controlled through software commands. The flash memory state
after programming or erasure can be checked through FLMSTR or the status register.

3.
To set the FMR01 bit to 1, write 0 to the bit and then write 1 to it
in a row.
Write to the FMR01 bit from an area outside the on-chip flash memory.
After a read array command, disable the CPU programming mode.
In user program mode, the programming control program should be executed
in the on-chip RAM or an external area.
EW0 mode processing procedures
EW0 Mode
Jump to the programming control program transferred
