19.3.1
Standard serial I/O mode has an ID code check function, and parallel I/O mode has a ROM code protect function to
prevent the flash memory from being read or rewritten easily.
This function is used 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 checked to see if they match. If the ID codes do
not match, the commands sent from the programmer are not acknowledged. The ID codes consist of 8 bits of
data each, the areas of which, beginning with the first byte, are 00FFDFh, 00FFE3h, 00FFEBh, 00FFEFh,
00FFF3h, 00FFF7h, and 00FFFBh. Write programs in which the ID codes are set at these addresses and write
them to the flash memory.
