a block not being erased returns valid data. During
suspension the memory will respond only to the
Erase Resume ER and the Program PG instruc-
tions. A Program operation can be initiated during
erase suspend in one of the blocks not being
erased. It will result in both DQ2 and DQ6 toggling
when the data is beingprogrammed. ARead/Reset
