Software Protected Program Cycle Waveform
(1, 2, 3)
Notes: 1. A8 through A18 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.
