Software Protected Program Waveform
Notes: 1. OE must be high when WE and CE are both low.
2. 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.
Programming Algorithm
3. Data in bytes not loaded within a sector being programmed
may be altered by the program operation; therefore, all
bytes within a sector must be loaded.

Address Format: A14 - A0 (Hex).
2. Data Protect state will be re-activated at end of program cycle.
