Also, asserting RP# aborts the block-erase operation, and array contents at the

programming within the block is attempted.
Suspend and Resume
An erase or programming operation can be suspended to perform other operations, and
then subsequently resumed.

All erase and programming operations require the addressed block to remain unlocked
with a valid voltage applied to VPEN throughout the suspend operation. Otherwise, the
block-erase or programming operation will abort, setting the appropriate Status
Register error bit(s). Also, asserting RP# aborts suspended block-erase and
programming operations, rendering array contents at the addressed location(s)
indeterminate.
