Bit
Cache program error bit (SR1)
The cache program error bit can be used to identify if the previous page (page N-1) has been
successfully programmed or not in a cache program operation. SR1 is set to ’1’ when the
cache program operation has failed to program the previous page (page N-1) correctly. If
SR1 is set to ‘0’ the operation has completed successfully.
The cache program error bit is only valid during cache program operations, during other
operations it is don’t care.
Error bit (SR0)
The error bit is used to identify if any errors have been detected by the P/E/R controller. The
error bit is set to ’1’ when a program or erase operation has failed to write the correct data to
the memory. If the error bit is set to ‘0’ the operation has completed successfully. The error
bit SR0, in a cache program operation, indicates a failure on page N.
