Notes:

6. CE

1 and WE are LOW and CE2 is HIGH for WRITE cycle.

7. OE is LOW for this WRITE cycle to show twz and tow.

8. If CE

1 goes HIGH or CE2 goes LOW simultaneously with WE HIGH, the output remains in a high impedance state.

9. Write Cycle Time is measured from the last valid address to the first transitioning address.
