A-3 STATUS REGISTER READ OPERATIONS
If AC timing for reading the status register described in specifications is not satisfied, a system processor can check the
status register bit SR.15 instead of SR.7 to determine when the erase or program operation has been completed.
Figure A-3-1. Example of Checking the Status Register
(In this example, the device contains four partitions.)
Table A-3-1. Status Register Definition (SR.15 and SR.7)
SR.15 = WRITE STATE MACHINE STATUS: (DQ
15
)
1 = Ready in All Partitions
0 = Busy in Any Partition
SR.7 = WRITE STATE MACHINE STATUS
FOR EACH PARTITION: (DQ
7
)
1 = Ready in the Addressed Partition
0 = Busy in the Addressed Partition
NOTES:
SR.15 indicates the status of WSM (Write State
Machine). If SR.15="0", erase or program operation is in
progress in any partition.
SR.7 indicates the status of the partition. If SR.7="0",
erase or program operation is in progress in the addressed
partition. Even if the SR.7 is "1", the WSM may be
occupied by the other partition.
