Write Cycle No. 1 (WE Controlled) [15, 19, 20]
Write Cycle No. 2 (CE Controlled) [15, 19, 20]
Notes:
19. Data I/O is high impedance if OE = V
IH
.
20. If CE goes HIGH simultaneously with WE = V
IH
, the output remains in a high-impedance state.
21. During this period, the I/Os are in output state and input signals should not be applied.
