NOTES :
Check RY/BY# or SR.7 to determine block erase or word
write completion. SR.6-0 are invalid while SR.7 =
If both SR.5 and SR.4 are
improper command sequence was entered.
SR.3 does not provide a continuous indication of V
The WSM interrogates and indicates the V
Block Erase or Word Write command sequences. SR.3 is not
guaranteed to reports accurate feedback only when V
V
The WSM interrogates the RP# only after Block Erase or
Word Write command sequences. It informs the system,
depending on the attempted operation, if the RP# is not V
SR.0 is reserved for future use and should be masked out
when polling the status register.
