Switching Waveforms
Write Cycle No. 1 (WE Controlled)
Write Cycle No. 2 (CE Controlled)
Notes:
19. Data I/O is high-impedance if OE = V
20. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
21. During the DON'T CARE period in the DATA I/O waveform, the I/Os are in output state and input signals should not be applied.
