Timing Waveforms
Write Cycle 1 (WE controlled)
Write Cycle 2 (CE controlled)
Notes
Document #: 001-06435 Rev. *D
13. This cycle is WE controlled, OE is HIGH during write.
14. Data in and/or out is high impedance if OE = V
15. During this period the IOs are in output state and input signals must not be applied.
16. This cycle is CE controlled.
17. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
