NOTES:
1. RY
/BY
output or BS bit must be checked to determine
completion of an operation (Block Lock, Suspend, Erase or
Data Write) before the appropriate Status bits (BOS, BLS)
is checked for success.
2. The BOAS bit will not be set until BSR.7 = 1.
3. Operation halted via Abort command.
4. BSR.1-0 = Reserved for future enhancements. These bits
are reserved for future use; mask them out when polling
the BSRs.
5. When multiple operations are queued, checking BSR.7
only provides indication of completion for that particular
block. GSR.7 provides indication when all queued opera-
tions are completed.
