End
Start
Execute read array command or reset flash
memory by setting flash memory reset bit (by
writing “1” and then “0” in succession) (Note 3)
Single-chip mode or Boot mode (Note 1)
Set CPU mode register (Note 2)
Using software command execute erase,
program, or other operation
Jump to control program transferred in RAM
(Subsequent operations are executed by control
program in this RAM)
Transfer CPU rewrite mode control program
to RAM
Notes1: When starting the MCU in the single-chip mode, supply 4.5 V to 5.5 V to the CNVss
pin until checking the CPU rewrite mode entry flag.
2: Set bits 6, 7 (main clock division ratio selection bits) at CPU mode register (003B16).
3: Before exiting the CPU rewrite mode after completing erase or program operation,
always be sure to execute the read array command or reset the flash memory.
Write “0” to CPU rewrite mode select bit
Set CPU rewrite mode select bit to “1” (by
writing “0” and then “1” in succession)
Check CPU rewrite mode entry flag
