NOTES:
1. RY
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
5. When multiple operations are queued, checking BSR.7 only
completion of an operation (Block Lock, Suspend, Erase or
Data Write) before the appropriate Status bits (BOS, BLS) is
checked for success.
These bits are reserved for future use; mask them out when
polling the BSRs.

GSR.7 provides indication when all queued operations are
completed.
