Note : When multiple sector erase over several banks is operated, the system cannot read out of the bank to which
a sector being erased belongs. For example, suppose that erasing is taking place at both Bank A and Bank B,
neither Bank A nor Bank B is read out (they would output the sequence flag once they were selected.)
Meanwhile the system would get to read from either Bank C or Bank D.
