NOTES:

BSR.7 = BLOCK STATUS

1 = Ready

0 = Busy

RY/BY# output or BS bit must be checked to

determine completion of an operation (block lock,

suspend, 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

BSR.2 = VPP STATUS

1 = VPP Error Detect, Operation Abort

0 = VPP OK

BSR.1 = VPP LEVEL

1 = VPP Detected at 5.0V ± 10%

0 = VPP Detected at 12.0V ± 5%

BSR.1 is not guaranteed to report accurate

feedback between the VPPH1 and VPPH2 voltage

ranges. Programs and erases with VPP between

VPPLK(max) and VPPH1 (min), between

VPPH1(max) and VPPH2(min), and above

VPPH2(max) produce spurious results and should

not be attempted.

BSR.4,3,0 = RESERVED FOR FUTURE ENHANCEMENTS

These bits are reserved for future use; mask them out when polling the BSRs.
