program.
Do not write additions to the OFS2 register. If the block including the OFS2 register is erased, the OFS2 register
is set to FFh.
When blank products are shipped, the OFS2 register 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 OFS2 register is the value programmed by the
user.
For a setting example of the OFS2 register, refer to 13.3.1 Setting Example of Option Function Select Area.
Assuming that the period from when the watchdog timer starts counting until it underflows is 100%, the refresh
acknowledgement period for the watchdog timer can be selected.
For details, refer to 14.3.1.1 Refresh Acknowledgment Period.
