The JTHW multiplexer port provides 8 inputs and 8 outputs at TTL levels. While these I/O 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/O that can be accessed on this port.
In multiplexed form, some of the SELn outputs are used to select which of the multiplexed I/O are to be
accessed.
