Notes: 1. Do not set multiple bits simultaneously.
2. P bit and E bit setting should be carried out in accordance with the program/erase
Do not release or cut the V
algorithms shown in section 6.7, Programming and Erasing Flash Memory.
A watchdog timer setting should be made beforehand to prevent the P or E bit from
being set for longer than the specified time.
See section 6.9, Flash Memory Programming and Erasing Precautions, for more
information on the use of these bits.
