Notes:

1. The option function select area is allocated in the flash memory, not in the SFRs. Set appropriate values as ROM data by a program.

Do not perform any additional writes to the option function select area. Erasing the block including the option function select area sets the option

function select area to FFh.

2. The ID code area is allocated in the flash memory, not in the SFRs. Set appropriate values as ROM data by a program. Do not perform any

additional writes to the ID code area. Erasing the block including the ID code area sets the ID code area to FFh.
