18.3.1
Standard serial I/O mode contains an ID code check function, and the parallel I/O mode contains a ROM
code protect function to prevent the flash memory from reading or rewriting easily.
Use this function in standard serial I/O mode. Unless the flash memory is blank, the ID codes sent
from the programmer and the ID codes written in the flash memory are determined whether they
match. If the ID codes do not match, the commands sent from the programmer are not
acknowledged. The ID code consists of 8-bit data, the areas of which, beginning with the first byte,
are 00FFDFh, 00FFE3h, 00FFEBh, 00FFEFh, 00FFF3h, 00FFF7h, and 00FFFBh. Write a program in
which the ID codes are set at these addresses and write it in the flash memory.
