Notes:
1. To prevent an erroneous operation, be sure to maintain CS#="H", and set the FeRAM in an inactive state
(standby mode) before and after power-on and power-off.
2. Powering on at the intermediate voltage level will cause an erroneous operation; thus, be sure to power up
from 0 V.
3. Enter all signals at the same time as power-on or enter all signals after power-on.
