Input Signal
Active state, when a bus or signal is driven, and enters a low impedance state
Tri-stated, when a bus or signal is placed in a high impedance state
Data Valid state, when a signal level has reached V
Data Invalid state, when a signal level is in transition between V
1. X address enable, all rows are disabled when XE = 0
2. Y address enable, YMUX is disabled when YE = 0
3. Sense amplifier enable
4. Output enable, tri-state Flash data out bus when OE = 0
Note: The midpoint is V
