REV. 0.6, AUG. 20, 2003
Table 6. Status Register Definition
SR.7 = WRITE STATE MACHINE STATUS (WSMS)
1 = Ready
0 = Busy
SR.6 = SECTOR ERASE SUSPEND STATUS (ESS)
1 = Sector ERASE Suspended
0 = Sector Erase in Progress/Completed
SR.5 = ERASE STATUS (ES)
1 = Error in Programming
0 = Successful Sector Erase or Clear Sector Lock-
Bits
SR.4 = PROGRAM STATUS (PS)
1 = Error in Programming
0 = Successful Programming
SR.3 = VPP STATUS (VPPS)
1 = VPP Low Detect, Operation Abort
0 = VPP OK
SR.2 = PROGRAM SUSPEND STATUS (PSS)
1 = Program Suspended
0 = Program in Progress/Completed
SR.1 = SECTOR LOCK STATUS
1 =Program/Erase attempted an a locked sector;
operation aborted
0 = No operation to locked sectors
SR.0 = RESERVED FOR FUTURE ENHANCEMENTS
(R)
NOTES:
Check WSM bit first to determine word program or sec-
tor Erase completion, before checking Program or Erase
Status bits.
When Erase Suspend is issued, WSM halts execution
and sets both WSMs and ESS bits to "1". ESS bit re-
mains set to "1" until an Erase Resume command is
issued.
When this bit (SR.5) is set to "1", it means WSM is
unable to verify successful sector erasure.
When this bit is set to "1", WSM has attempted but failed
to program a word.
SR.3 bit is not guaranteed to report accurate feedback
between VPPLK and VPP min.
When program suspend is issued, WSM halts the ex-
ecution and sets both WSMs and SR.2 bit to "1". SR.2
remains set to "1" until a Program Resume command is
issued.
If a program or erase operation is attempted to one of
the locked sectors, this bit is set by the WSM. The op-
eration specified is aborted and the device is returned to
read status mode.
SR. 0 is reserved for future use and should be masked
out when polling the status register.
