Notes:
1. Other operations except for those indicated in this column are inhibited.
2. Do not apply CE#f = V
3. Don’t care or open LB#s or UB#s.
4. If WP#/ACC = V
5. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “” section.
6. If WP#/ACC = V
