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
Table 1
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.
