Figure 24. Quadruple Word Program Flowchart and Pseudo Code
Note: 1. Status check of SR1 (Protected Block), SR3 (VPP Invalid) and SR4 (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.
4. Any address within the bank can equally be used.
