Figure 18. Quadruple Byte Program Flowchart and Pseudo Code (FWH Interface Only)
Note: 1. A Status check of b3 (VPP invalid) and b4 (Program Error) can be made after each Program operation by following the correct com-
mand sequence.
2. If an error is found, the Status Register must be cleared before further Program/Erase Controller operations.
3. A1 and A0 are treated as Don’t Care. Starting at the Start Address, the first data byte is programmed at the address that has A1-
A0 at 00, the second at the address that has A1-A0 at 01, the third at the address that has A1-A0 at 10, and the fourth at the address
that has A1-A0 at 11.
