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 at 1 until an
Erase Resume command is issued.
When this bit is set to 1, WSM has applied the maximum
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.
