When program suspend is issued, WSM halts execution and
sets both WSMS and PSS bits to 1. The 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, the WSM sets this bit. The operation specified is
aborted and the flash memory device returns to read status
mode.
This bit is reserved for future use and must be masked out
when polling the Status Register.
