NOTES:
1. A0-A14 must conform to the addressing sequence for the first three bytes as shown above.
2. After the command sequence has been issued and a page write operation follows, the page address inputs
(A7-A18) must be the same for each high to low transition of WE\ (or CE\).
3. OE\ Must be high only when WE\ and CE\ are both low.
4. A17 and A18 must remain valid throughout the WE\ and CE\ low cycle.
