Product Specification
Status check of SR1 (Protected Block), SR3 (VPP Invalid) and SR4 (Program Error) can be made after each program operation or after a sequence.
If an error is found, the Status Register must be cleared before further Program/Erase Controller operations.
Any address within the bank can equally be used.
To read the memory in Asynchronous mode, the CR15 Configuration Register bit must be written to 1.
