Read Cycle No. 2 (OE Controlled)[12, 13]
Write Cycle No. 1 (CE1 or CE2 Controlled)
[14, 15]
Notes:
13. Address valid prior to or coincident with CE1 transition LOW and CE2 transition HIGH.
14. Data I/O is high impedance if OE = VIH.
15. If CE1 goes HIGH or CE2 goes LOW simultaneously with WE going HIGH, the output remains in a high-impedance state.
