NOTES:
SR.7 = WRITE STATE MACHINE STATUS
1 = Ready
0 = Busy
Check RY/BY# or SR.7 to determine block erase,
program, or lock-bit configuration completion.
SR.6
–0 are invalid while SR.7 = “0.”
SR.6 = ERASE SUSPEND STATUS
1 = Block Erase Suspended
0 = Block Erase in Progress/Completed
SR.5 = ERASE AND CLEAR LOCK-BITS
STATUS
1 = Error in Block Erasure or Clear Lock-Bits
0 = Successful Block Erase or Clear Lock-Bits
If both SR.5 and SR.4 are
“1”s after a block erase or
lock-bit configuration attempt, an improper
command sequence was entered.
SR.4 = PROGRAM AND SET LOCK-BIT
STATUS
1 = Error in Program or Set Master/Block
Lock-Bit
0 = Successful Program or Set Master/Block
Lock-Bit
SR.3 = V

STATUS
1 = V

SR.3 does not provide a continuous indication of
V
PP
level. The WSM interrogates and indicates the
V
PP
level only after a block erase, program, or lock-
bit configuration operation. SR.3 is not guaranteed
to reports accurate feedback only when V

SR.2 = PROGRAM SUSPEND STATUS
1 = Program Suspended
0 = Program in Progress/Completed
SR.1 = DEVICE PROTECT STATUS
1 = Master Lock-Bit, Block Lock-Bit and/or
RP# Lock Detected, Operation Abort
0 = Unlock
SR.1 does not provide a continuous indication of
master and block lock-bit values. The WSM
interrogates the master lock-bit, block lock-bit, and
RP# only after a block erase, program, or lock-bit
configuration operation. It informs the system,
depending on the attempted operation, if the block
lock-bit is set, master lock-bit is set, and/or
RP#

SR.0 = RESERVED FOR FUTURE
ENHANCEMENTS
SR.0 is reserved for future use and should be
masked out when polling the status register.
