Notes: 1. The programming operation is not guranteed when the number of the SC pulse exceeds 64.
2. Any commands, including reset command FFH, cannot be input while RDY/Busy is V_OL.
3. The status returns to the standby status after RDY/Busy returns to High-Z.
4. By using program (3), the data can be programmed additionally for each sector before erase.
