qID Code Check
This command checks the ID code. Execute the boot ID check
command as explained here following.
qID 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
FFC216 to FFC816. Write a program into the flash memory, which
already has the ID code set for these addresses.

Fig. 98 ID code storage addresses
(1) Transfer the “F516” command code with the 1st byte.
(2) Transfer addresses AB0 to AB7, AB8 to AB15 and AB16 to AB23
(“0016”) of the 1st byte of the ID code with the 2nd and 3rd re-
spectively.
(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.
