ID Check
This command checks the ID code. Execute the boot ID check
command as explained here following.
G
ID Code
When the flash memory is not blank, the ID code sent from the se-
rial programmer and the ID code written in the flash memory are
compared to see if they match. If the codes do not match, the
command sent from the serial programmer is not accepted. An ID
code contains 8 bits of data. Area is, from the 1st byte, addresses
FFD4
16
to FFDA
16
. Write a program into the flash memory, which
already has the ID code set for these addresses.

of the 1st byte of the ID code with the 2nd, 3rd, and 4th bytes
respectively.
(3) Transfer the number of data sets of the ID code with the 5th
byte.
(4) Transfer the ID code with the 6th byte onward, starting with the
1st byte of the code.
