Notes:
11.
CE
1 and WE must be LOW, and CE2 HIGH for WRITE cycle.
12.
OE is LOW for this WRITE cycle to show t
WZ and tOW.
13. If
CE
1 goes HIGH, or CE2 goes LOW, simultaneously with WE HIGH,
the output remains in a high impedance state.
14. Write Cycle Time is measured from the last valid address to the first
transitioning address.
