Notes:
1. A0 - A14 must conform to the addressing sequence for the first 3 bytes as shown above.
2. After the command sequence has been issued and a page write operation follows, the page
3. OE must be high only when WE and CE are both low.
address inputs (A7 - A16) must be the same for each high to low transition of WE (or CE).
