33.3.1
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.
The ID code check function is used in standard serial I/O mode. Unless 3 bytes (addresses 0FFFCh to 0FFFEh)
of the reset vector are set to FFFFFFh, the ID codes sent from the serial programmer or the on-chip debugging
emulator and the 7-byte 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 serial programmer or the on-chip debugging emulator are not
accepted. For details of the ID code check function, refer to 12. ID Code Areas.
