NOTES:
BSR.7 = BLOCK STATUS
1 = Ready
0 = Busy
[1]
RY/BY# output or BS bit must be checked to
determine completion of an operation (block lock,
erase suspend, any RY/BY# reconfiguration, Upload
Status Bits, block erase or data program) before the
appropriate Status bits (BOS, BLS) is checked for
success.
BSR.6 = BLOCK-LOCK STATUS
1 = Block Unlocked for Program/Erase
0 = Block Locked for Program/Erase
BSR.5 = BLOCK OPERATION STATUS
1 = Operation Unsuccessful
0 = Operation Successful or Currently
Running
The BOAS bit will not be set until BSR.7 = 1.
BSR.4 = BLOCK OPERATION ABORT STATUS
1 = Operation Aborted
0 = Operation Not Aborted
MATRIX
5/4
0 0 = Operation Successful or
Currently Running
0 1 = Not a Valid Combination
1 0 = Operation Unsuccessful
1 1 = Operation Aborted
Operation halted via Abort command.
BSR.3 = QUEUE STATUS
1 = Queue Full
0 = Queue Available
BSR.2 = V

BSR.1
–0 = RESERVED FOR FUTURE ENHANCEMENTS
These bits are reserved for future use; mask them out when polling the BSRs.
NOTE:
1.
When multiple operations are queued, checking BSR.7 only provides indication of completion for that particular block.
GSR.7 provides indication when all queued operations are completed.
