The six consecutive addresses must be in order listed (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. See STORE cycle and RECALL cycle tables and
diagrams for further details.
The following six-address sequence is used for testing purposes and should not be used: 0000, 1555, 0AAA, 1FFF, 10F0, 139C.
