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.
