Write Cycle No. 1 (CE Controlled)[12, 13]
Write Cycle No. 2 (BLE or BHE Controlled)
Notes:
11. Address valid prior to or coincident with CE transition LOW.
12. Data I/O is high impedance if OE or BHE and/or BLE= VIH.
13. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
