If any of the three Reference Select input functions are not configured, then
the software will still follow the table, but will treat the unconfigured inputs as
if they are permanently open.
As an example, the table below describes what reference selections can be
made if "Speed Select 1" is the only configured input function. This
configuration allows a single input to choose between [Speed Ref A Sel] and
[Speed Ref B Sel].

As another example, describes what reference selections can be made if the
