EW0 Mode Operating Procedure
Jump to a rewrite control program which has been
transferred to any areas other than the flash memory
(The subsequent process is executed by the rewrite
control program in any areas other than the flash
memory)
Transfer a rewrite control program which uses CPU
rewrite mode to any areas other than the flash
memory
Figure 18.8 shows the How to Set and Exit EW0 Mode. Figure 18.9 shows the How to Set and Exit
EW1 Mode.
NOTES :
1. Select 5MHz or below for CPU clock by the CM06 bit in the CM0 register and the CM16 to CM17 bits in the CM1 register.
2. When setting the FMR01 bit to “1”, write “0” to the FMR01 bit before writing “1”. Do not generate an interrupt between writing “0” and
3. Disable CPU rewrite mode after executing the read array command.
