Check SR.7 to determine block erase or byte write
completion. SR.6-0 are invalid while SR.7="0".
If both SR.5 and SR.4 are "1"s after a block erase 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 or Byte Write command sequences. SR.3 is not
guaranteed to reports accurate feedback only when
V
The WSM interrogates the WP# and RP# only after Block
Erase or Byte Write command sequences. It informs the
system, depending on the attempted operation, if the WP# is
not V
SR.0 is reserved for future use and should be masked out
when polling the status register.
