ID Check
ID Code
(M16C transmit
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 units 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 units 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.
RTS1(BUSY)
(1) Transfer the “F5
(2) Transfer addresses A
(3) Transfer the number of data sets of the ID code with the 5th byte.
(4) The ID code is sent with the 6th byte onward, starting with the 1st byte of the code.
3rd and 4th bytes respectively.
