Notes
SR7 WRITE STATE MACHINE STATUS (WSMS)
1 = Ready
0 = Busy
Check Write State Machine bit first to determine Word Program
or Sector Erase completion, before checking program or erase
status bits.
SR6 = ERASE SUSPEND STATUS (ESS)
1 = Erase Suspended
0 = Erase In Progress/Completed
When Erase Suspend is issued, WSM halts execution and sets
both WSMS and ESS bits to “1” – ESS bit remains set to “1” until
an Erase Resume command is issued.
SR5 = ERASE STATUS (ES)
1 = Error in Sector Erase
0 = Successful Sector Erase
When this bit is set to “1”, WSM has applied the max number of
erase pulses to the sector and is still unable to verify successful
sector erasure.
SR4 = PROGRAM STATUS (PRS)
1 = Error in Programming
0 = Successful Programming
When this bit is set to “1”, WSM has attempted but failed to
program a word
SR3 = VPP STATUS (VPPS)
1 = VPP Low Detect, Operation Abort
0 = VPP OK
The V
PP
status bit does not provide continuous indication of VPP
level. The WSM interrogates V
PP
level only after the Program or
Erase command sequences have been entered and informs the
system if V
PP
has not been switched on. The V
PP
is also checked
before the operation is verified by the WSM.
SR2 = PROGRAM SUSPEND STATUS (PSS)
1 = Program Suspended
0 = Program in Progress/Completed
When Program Suspend is issued, WSM halts execution and
sets both WSMS and PSS bits to “1”. PSS bit remains set to “1”
until a Program Resume command is issued.
SR1 = SECTOR LOCK STATUS
1 = Prog/Erase attempted on a locked sector; Operation aborted.
0 = No operation to locked sectors
If a Program or Erase operation is attempted to one of the locked
sectors, this bit is set by the WSM. The operation specified is
aborted and the device is returned to read status mode.
SR0 = Plane Status (PLS)
Indicates program or erase status of the addressed plane.

Description
0
0
The addressed plane is performing a program/erase operation.
0
1
A plane other than the one currently addressed is performing a program/erase operation.
1
x
No program/erase operation is in progress in any plane. Erase and Program suspend bits (SR6, SR2)
indicate whether other planes are suspended.
