Figure 15. Quadruple Byte Program Flowchart and Pseudo Code (A/A Mux Interface Only)
Note: 1. A Status check of b3 (V
PP
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. Address 1, Address 2, Address 3 and Address 4 must be consecutive addresses differing only for address bits A0 and A1.
