Read Cycle No. 2 (OE Controlled)[14, 15]
Write Cycle No. 1 (WE Controlled)[16, 18]
Notes:
15.Address valid prior to or coincident with CE transition LOW.
16.Data I/O is high impedance if OE = VIH.
17.During this period, the I/Os are in output state and input signals should not be applied.
18.If CE goes HIGH simultaneously with WE HIGH, the output remains in high-impedance state.
