Figure 19. Quadruple Word Program Flowchart and Pseudo Code
Note: 1. Status check of b1 (Protected Block), b3 (VPP Invalid) and b4 (Program Error) can be made after each program operation or after
a sequence.
2. If an error is found, the Status Register must be cleared before further Program/Erase operations.
3. Address 1 to Address 4 must be consecutive addresses differing only for bits A0 and A1.
