Notes 1:
For this bit to be set to
“1”, the user needs to write a
“
0” and then a
“1” to it in succession. For this bit to be set to “0”, write
“
0” only to
this bit.
2:
Effective only when the CPU rewrite mode select bit =
“
1”.

End
Start
Execute read array command (Note 2)
Single-chip mode or Boot mode
Set CPU mode register (Note 1)
Using software command executes erase,
program, or other operation
Jump to control program transferred to internal
RAM
(Subsequent operations are executed by control
program in this RAM)
Transfer CPU rewrite mode control program to
internal RAM
Notes 1: Set the main clock as follows depending on the clock division ratio selection bits of CPU
mode register (bits 6, 7 of address 003B16).
2 : Before exiting the CPU rewrite mode after completing erase or program operation, always
be sure to execute the read array command.
Write “0” to CPU rewrite mode select bit
Set CPU rewrite mode select bit to “1” (by
writing “0” and then “1” in succession)
Set all user block E/W enable bit to “1”
(by writing “0” and then “1” in succession)
Set 8 KB user block E/W enable bit
(At E/W disabled; writing “0”, at E/W enabled;
writing “0” and then “1” in succession)
Set all user block E/W enable bit to “0”
Set 8 KB user block E/W enable bit to “0”
