GSR.7 = WRITE STATE MACHINE STATUS (WSMS)
1 = Ready
0 = Busy
GSR.6 = OPERATION SUSPEND STATUS (OSS)
1 = Operation Suspended
0 = Operation in Progress/Completed
GSR.5 = DEVICE OPERATION STATUS (DOS)
1 = Operation Unsuccessful
0 = Operation Successful or Currently Running
GSR.4 = DEVICE SLEEP STATUS(DSS)
1 = Device in Sleep
0 = Device Not in Sleep
MATRIX 5/4
00 = Operation Successful or Currently Running
01 = Device in Sleep Mode or Pending Sleep
10 = Operation Unsuccessful
11 = Operation Unsuccessful or Aborted
GSR.3 = QUEUE STATUS (QS)
1 = Queue Full
0 = Queue Available
GSR.2 = PAGE BUFFER AVAILABLE STATUS (PBAS)
1 = One or Two Page Buffers Available
0 = No Page Buffer Available
GSR.1 = PAGE BUFFER STATUS (PBS)
1 = Selected Page Buffer Ready
0 = Selected Page Buffer Busy
GSR.0 = PAGE BUFFER SELECT STATUS (PBSS)
1 = Page Buffer 1 Selected
0 = Page Buffer 0 Selected
NOTES:
1. RY
/BY
output or WSMS bit must be checked to determine
completion of an operation (Block Lock, Suspend, any
RY
/BY
reconfiguration, Upload Status Bits, Erase or Data
Write) before the appropriate Status bit (OSS or DOS) is
checked for success.
2. If operation currently running, then GSR.7 = 0.
3. If device pending sleep, then GSR.7 = 0.
4. Operation aborted: Unsucccessful due to Abort command.
5. The device contains two Page Buffers.
6. Selected Page Buffer is currently busy with WSM operation.
7. 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.
