*1 : Other operations except for indicated this column are inhibited.
*2 : WE can be VIL if OE is VIL, OE at VIH initiates the write operations.
*3 : Do not apply CEf = VIL, CE1s = VIL and CE2s = VIH at a time.
*4 : It is also used for the extended sector group protections.
*5 : WP/ACC = VIL; protection of boot sectors.
WP/ACC = VIH; removal of boot sectors protection.
WP/ACC = VACC (9 V); Program time will reduce by 40%.
