Notes
25. The software sequence is clocked with CE controlled or OE controlled reads.
26. The six consecutive addresses must be read in the order listed in
26. The six consecutive addresses must be read in the order listed in
on page 5. WE must be HIGH during all six consecutive cycles. After the sixth address read
cycle, no further read or write operation must be performed for t
SS
duration. If these conditions are not met, the software sequence is aborted.
