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.
2:
Effective only when the CPU rewrite mode select bit = 1. Set this bit to
0
subsequently
after setting it to
1
(reset).

Transfer CPU rewrite mode control
program to internal RAM
Notes 1:
Set bit 6, 7 (Main clock division ratio selection bits ) at CPU mode register (003B
16
).
2:
Before exiting the CPU rewrite mode after completing erase or program operation, always be sure to
execute a read array command or reset the flash memory.
