NOTES:
Procedure to enter EW0 mode
Transfer the rewrite control program in CPU rewrite
mode to a space other than the flash memory
1.In CPU rewrite mode, set the CM06 bit in the CM0 register and bits CM17 to CM16 in the CM1 register to CPU
2.Set the FMR01 bit to 1 immediately after setting it to 0. Do not generate an interrupts or DMA transfer between
3.Exit CPU rewrite mode after executing the read array command.
4.When CPU rewrite mode is exited while the FMR05 bit is set to 1, the user ROM area can be accessed.
5.When in CPU rewrite mode, bits PM10 and PM13 in the PM1 register are set to 1. The rewrite control program

Set the bit to 0 if setting to 0. Set this bit in a space other than the flash memory while the NMI pin is held "H".
can only be executed in the internal RAM or in an external area that is enabled for use when the PM13 bit = 1.
Single-chip mode, memory expansion mode
1.In EW1 mode, do not enter the memory expansion mode or boot mode.
2.In CPU rewrite mode, set the CM06 bit in the CM0 register and bits CM17 to CM16 in the CM1 register to

setting the bit to 0 and setting it to 1.
Set the FMR11 bit to 1 immediately after setting it to 0 while the FMR01 bit is set to 1.
Do not generate an interrupt or a DMA transfer between setting the FMR11 bit to 0 and setting it to 1.
Set bits FMR01 and FMR11 while "H" is applied to the NMI pin.
