Notes:
Write Cycle No.2 (CE Controlled)
Write Cycle No. 3 (WE Controlled, OE LOW)
10. Device is continuously selected. OE, CE = V
12. Address valid prior to or coincident with CE transition LOW.
13. Timing parameters are the same for all chip enable signals (CE
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.
11. WE is HIGH for read cycle.
