4.6 Global Status Register
NOTE:
1. When multiple operations are queued, checking BSR.7 only provides indication of completion for that particular block.

GSR.7 = WRITE STATE MACHINE STATUS
GSR.6 = OPERATION SUSPEND STATUS
GSR.5 = DEVICE OPERATION STATUS
GSR.4 = DEVICE SLEEP STATUS
MATRIX 5/4
GSR.3 = QUEUE STATUS
GSR.2 = PAGE BUFFER AVAILABLE STATUS
GSR.1 = PAGE BUFFER STATUS
GSR.0 = PAGE BUFFER SELECT STATUS
GSR.7 provides indication when all queued operations are completed.

NOTES:
[1]
to determine completion of an operation (block
lock, suspend, any RY/BY# reconfiguration,
Upload Status Bits, erase or data program)
before the appropriate Status bit (OSS or DOS)
is checked for success.
If operation currently running, then GSR.7 = 0.
If device pending sleep, then GSR.7 = 0.
Operation aborted: Unsuccessful due to Abort
command.
The device contains two Page Buffers.
Selected Page Buffer is currently busy with WSM
operation
RY/BY# output or WSMS bit must be checked
