Switching Waveforms
Write Cycle No. 1 (WE Controlled)
Write Cycle No. 2 (CE Controlled)
Write Cycle No. 3 (WE Controlled, OE LOW)
Notes:
14. Data I/O is high impedance if OE = V
15. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
16. During this period, the I/Os are in the output state and input signals should not be applied.
