After the Chip Erase operation has completed the
memory will return to the Read Mode, unless an
error has occurred. When an error occurs the
memory will continue to output the Status Regis-
ter. A Read/Reset command must be issued to re-
set the error condition and return to Read Mode.

Note: A Bus Read must be done between each Write cycle where the data is programmed or verified, to Read the Status Register and check
that the memory is ready to accept the next data. SA is the Start Address. CA is the Continue Address. FA is the Final Address. X Don’t
