Software Protected Program Cycle Waveform
(1, 2, 3)
Notes: 1. A8 through A17 must specify the sector address
during each high to low transition of WE (or CE)
after the software code has been entered.
2. OE must be high when WE and CE are both low.
3.
All bytes that are not loaded within the sector being
programmed will be indeterminate.

Notes for software program code:
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.
