*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 : Protect of “outermost” 2 x 8 Kbytes on both ends of each boot block sector.
