17.3 Functions To Prevent Flash Memory from Rewriting
To prevent the flash memory from being read or rewritten easily, standard serial I/O mode has an ID code
check function.
17.3.1 ID Code Check Function
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 compared 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, the areas of which, beginning with the first byte, are 00FFDF
00FFEB
codes are preset at these addresses and write it in the flash memory.
