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