Software Data Protection Disable
Algorithm(1)
NOTES:
1. Byte Data Format: I/O7 - I/O0, I/
Address Format: A14 - A0 (Hex)
2. Write Protect state will be active at end of write even if no other
data is loaded.
3. Write Protect state will be deactivated at end of period even if no
other data is loaded.
4. 1 to 128 bytes of data are loaded.

1. A0-A14 of the selected I/O bytes 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-A16) of the selected I/O bytes 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.
