RY/BY# output or WSMS bit must be checked to
determine completion of an operation (erase,
erase suspend, or data program) before the
appropriate Status bit (ESS, ES or DWS) is
checked for success.
If DWS and ES are set to “1” during an erase
attempt, an improper command sequence was
entered. Clear the CSR and attempt the
operation again.
The VPPS bit, unlike an A/D converter, does not
provide continuous indication of V
WSM interrogates V
Program or Erase command sequences have
been entered, and informs the system if V
not been switched on. VPPS is not guaranteed to
report accurate feedback between V
and V
