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.
When blank products are shipped, the option function select area is set to FFh. It is set to the written value after written by the user.
When factory-programming products are shipped, the value of the option function select area is the value programmed by the user.
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.
When blank products are shipped, the ID code areas are set to FFh. They are set to the written value after written by the user.
When factory-programming products are shipped, the value of the ID code areas is the value programmed by the user.
