â¢ 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

programmer 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 program which has had the ID code preset at these

addresses to the flash memory.
