Start
Execute read array command or reset flash
memory by setting flash memory reset bit (by
writing
“
1
”
and then
“
0
”
in succession) (Note 2)
Single-chip mode, or boot mode
Set CPU mode register (Note 1)
Using software command execute erase,
program, or other operation
Jump to transferred control program in RAM
(Subsequent operations are executed by control
program in this RAM)
Transfer CPU reprogram 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 reprogram mode after completing erase or program operation, always be sure to
execute a read array command or reset the flash memory.
Write
“
0
”
