Software Protected Write Cycle Waveforms
(1, 2)
Notes: 1. A6 through A12 must specify the same page address during each high to low transition of WE (or CE) after
the software code has been entered.
2. OE must be high only when WE and CE are both low.

Notes for software program code:
1. Data Format: I/O7 - I/O0 (Hex);
Address Format: A12 - A0 (Hex).
2. Write Protect state will be activated at end of write even if no
other data is loaded.
3. Write Protect state will be deactivated at end of write period
even if no other data is loaded.
4. 1 to 64-bytes of data are loaded.
