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 an additional write to the option function select area. Erasure of the block including the option function select area causes the

option function select area to be set 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 an additional write to the ID code area. Erasure of the block including the ID code area causes the ID code area to be set to FFh.
