Note m: The software sequence is clocked with E controlled reads.
Note n: The six consecutive addresses must be in the order listed in the Software STORE/RECALL Mode Selection Table: (0000, 1555, 0AAA, 1FFF,
10F0, 0F0F) for a STORE cycle or (0000, 1555, 0AAA, 1FFF, 10F0, 0F0E) for a RECALL cycle. W must be high during all six consecutive
cycles.
