1. Data Format: I/O7 - I/O0 (Hex); Address Format: A14 - A0 (Hex).
2. Data Protect state will be activated at end of program cycle.
3. Data Protect state will be deactivated at end of program period.
4. 256 bytes of data MUST BE loaded.
1. A8 through A17 must specify the sector address during each high-to-low transition of WE (or CE) after the software code
4. OE must be high when WE and CE are both low.
5. All bytes that are not loaded within the sector being programmed will be indeterminate.
