NOTES:
Check RY/BY# or SR.7 to determine block erase, byte
write, or lock-bit configuration completion.
SR.6-0 are invalid while SR.7="0".
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.3 does not provide a continuous indication of V
level. The WSM interrogates and indicates the V
only after Block Erase, Byte Write, Set Block/Master
Lock-Bit, or Clear Block Lock-Bits command sequences.
SR.3 is not guaranteed to reports accurate feedback
only when V
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 Block
Erase, Byte Write, or Lock-Bit configuration command
sequences. It informs the system, depending on the
attempted operation, if the block lock-bit is set, master
lock-bit is set, and/or RP# is not V
lock and master lock configuration codes after writing
the Read Identifier Codes command indicates master
and block lock-bit status.
SR.0 is reserved for future use and should be masked
out when polling the status register.
