The JTHW multiplexer port provides 8 inputs and 8 outputs at TTL levels. While these I/Os can be used
in unmultiplexed form for 16 discrete I/O points, most users will utilize PMAC software and accessories
to use this port in multiplexed form to greatly multiply the number of I/Os that can be accessed on this
port. In multiplexed form, some of the SELn outputs are used to select which of the multiplexed I/Os are
to be accessed.
