17.3 Functions To Prevent Flash Memory from Rewriting
To prevent the flash memory from being read or rewritten easily, standard serial input/output mode has
an ID code check function.
17.3.1 ID Code Check Function
Use this function in standard serial input/output 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
00FFE3
the ID codes are preset at these addresses and write it in the flash memory.
