Notes:
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 Controller operations.
3.
Any address within the bank can equally be used.
4.
To read the memory in Asynchronous mode, the CR15 Configuration Register bit must be written to 1.
