Since the Control Word Register and the three Counters have
separate addresses (selected by the A1, A0 inputs), and each
Control Word specifies the Counter it applies to (SC0, SC1
bits), no special instruction sequence is required. Any
programming sequence that follows the conventions above is
acceptable.
