Timing Waveforms
Write Cycle No. 2 (CE Controlled)
Write Cycle No. 3 (WE Controlled, OE Low)
Notes:
16. This cycle is CE controlled.
17. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
18. The cycle is WE controlled, OE LOW. The minimum write cycle time is the sum of t
