17. Programming Algorithm
Notes: 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 128 bytes of data are loaded.
18. 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. After the command sequence has been issued and a page write operation follows, the page address inputs (A7 - A16) must
be the same for each high to low transition of WE
(or CE).
3. OE
must be high only when WE and CE are both low.
