Note: This device also supports CE# controlled Block-Erase operation. The WE# and CE# signals are inter-
changeable as long as minimum timings are met. (See Table 18).
BAX = Block Address
WP# must be held in proper logic state (VIL or VIH) 1µs prior to and 1µs after the command sequence.
X can be VIL or VIH, but no other value.
