STATUS REGISTER BITS
NOTES
SR7 = WRITE STATE MACHINE STATUS (ISMS)
1 = Ready
0 = Busy
Check STS or SR7 to determine block
erase, program, or lock bit
configuration completion. SR6–SR0 are
not driven while SR7 = 0.
Yes
SR6 = ERASE SUSPEND STATUS (ESS)
1 = Block Erase Suspended
0 = Block Erase in Progress/Completed
SR5 = ERASE AND CLEAR LOCK BITS STATUS (ECLBS)
1 = Error in Block Erasure or Clear Lock Bits
0 = Successful Block Erase or Clear Lock Bits
Yes
If both SR5 and SR4 are “1s” after a
block erase or lock bit configuration
attempt, an improper command
sequence was entered.
Yes
SR4 = PROGRAM AND SET LOCK BIT STATUS (PSLBS)
1 = Error in Programming or Setting Block Lock Bits
0 = Successful Program or Set Block Lock Bits
SR3 = PROGRAMMING VOLTAGE STATUS (V
PENS
)
1 = Low Programming Voltage Detected,
Operation Aborted
0 = Programming Voltage OK
Yes
SR3 does not provide a continuous
programming voltage level indication.
The ISM interrogates and indicates the
programming voltage level only after
block erase, program, set block lock
bits, or clear block lock bits command
sequences.
Yes
SR2 = PROGRAM SUSPEND STATUS (PSS)
1 = Program Suspended
0 = Program in Progress/Completed
SR1 = DEVICE PROTECT STATUS (DPS)
1 = Block Lock Bit Detected, Operation Aborted
0 = Unlock
Yes
SR1 does not provide a continuous
indication of block lock bit values. The
ISM interrogates the block lock bits
only after block erase, program, or lock
bit configuration command sequences.
It informs the system, depending on
the attempted operation, if the block
lock bit is set. Read the block lock
configuration codes using the READ
IDENTIFIER CODES command to
determine block lock bit status. SR0 is
reserved for future use and should be
masked when polling the status
register.
Yes
SR0 = RESERVED FOR FUTURE ENHANCEMENTS
