Status Register indicates the status of the WSM (Write State
Machine).
Check SR.7 to determine block erase, full chip erase,
program or OTP program completion. SR.6 - SR.1 are invalid
while SR.7="0".
If both SR.5 and SR.4 are "1"s after a block erase, full chip
erase, program, set/clear block lock bit, set block lock-down
bit attempt, an improper command sequence was entered.
SR.3 does not provide a continuous indication of V
The WSM interrogates and indicates the V
Block Erase, Full Chip Erase, Program or OTP Program
command sequences. SR.3 is not guaranteed to report
accurate feedback when V
SR.1 does not provide a continuous indication of block lock
bit. The WSM interrogates the block lock bit only after Block
Erase, Full Chip Erase, Program or OTP Program command
sequences. It informs the system, depending on the attempted
operation, if the block lock bit is set. Reading the block lock
configuration codes after writing the Read Identifier Codes/
OTP command indicates block lock bit status.
SR.15 - SR.8 and SR.0 are reserved for future use and should
be masked out when polling the status register.
