Check Write State Machine bit first to determine Word Program
or Block Erase completion, before checking program or erase-
status bits.
When Erase Suspend is issued, WSM halts execution and sets
both WSMS and ESS bits to “1.” ESS bit remains set to “1” until
an Erase Resume command is issued.
When this bit is set to “1,” WSM has applied the max. number
of erase pulses to the block and is still unable to verify
successful block erasure.
When this bit is set to “1,” WSM has attempted but failed to
program a word/byte.

When Program Suspend is issued, WSM halts execution and
sets both WSMS and PSS bits to “1.” PSS bit remains set to “1”
until a Program Resume command is issued.
If a Program or Erase operation is attempted to one of the
locked blocks, this bit is set by the WSM. The operation
specified is aborted and the device is returned to read status
mode.
This bit is reserved for future use and should be masked out
when polling the status register.
