(2) ID Code Check Function
Use this function in standard serial I/O mode. When the contents
of the flash memory are not blank, the ID code sent from the pro-
grammer is compared with the ID code written in the flash memory
to see if they match. If the ID codes do not match, the commands
sent from the programmer are not accepted. The ID code consists
of 8-bit data, and its areas are FFD416 to FFDA16. Write a pro-
gram which has had the ID code preset at these addresses to the
flash memory.
