ID Check
ID Code
This command checks the ID code. Execute the boot ID check command as explained here following.
When the flash memory is not blank, the ID code sent from the peripheral unit 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 peripheral unit is not accepted. An ID code contains 8 bits of data. Area is, from the 1st byte,
addresses 0FFFDF
a program into the flash memory, which already has the ID code set for these addresses.
(M16C reception
(1) Send the “F5
(2) Send addresses A
(3) Send the number of data sets of the ID code in the 5th byte.
(4) The ID code is sent in the 6th byte onward, starting with the 1st byte of the code.
