CE 1 and WE must be LOW, and CE2 HIGH for WRITE cycle. 12. OE is LOW for this WRITE cycle to show t WZ and tOW. 13. If CE 1 goes HIGH, or CE2 goes LOW, simultaneously with WE HIGH, the output remains in a high impedance state 14. Write Cycle Time is measured from the last valid address to the first transitioning address. |
