Switching Waveforms
Write Cycle No. 1 (CE Controlled)
Write Cycle No. 2 (WE Controlled, OE HIGH During Write)
Notes:
Document #: 38-05169 Rev. *A
15. Data I/O is high impedance if OE = V
16. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
17. During this period the I/Os are in the output state and input signals should not be applied.
