Programming Algorithm
Notes for software program code:
1.
Data Format: I/O7 - I/O0 (Hex);
Address Format: A14 - A0 (Hex).
2.
Data protect state will be re-activated at the end of
program cycle.
3.
1 to 64 bytes of data are loaded.
Software Protected Program Cycle Waveforms(1)(2)(3)
Notes:
1.
A0 - A14 must conform to the addressing sequence for the first three bytes as shown above.
2.
A6 through A14 must specify the same page address during each high to low transition of WE (or CE) after the software
code has been entered.
3.
OE must be high only when WE and CE are both low.
