qID 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

FFD416 to FFDA16. Write a program into the flash memory, which

already has the ID code set for these addresses.

(1) Transfer the “F516” command code with the 1st byte.

(2) Transfer addresses A0 to A7, A8 to A15 and A16 to A23 (“0016”)

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.
