+ \item In-Muxer selection number (0,1,2,3) obviously has to match
+ with Out-Muxer order (otherwise a bi-directional FN
+ needs different Mux-register settings for
+ selecting either IN or OUT)
+ \vspace{6pt}
+ \item Priority-mux selection values do not actually matter,
+ and have nothing to do with the actual Muxer settings.
+ \vspace{6pt}
+ \item GPIO FN's input muxer is nothing more than an AND gate\\
+ (you never route more than one pin to one GPIO)
+ \vspace{6pt}
+ \item Any other FN with only 1:1 In also an AND gate \\
+ (this just always happens to be true for GPIO)
+ \vspace{6pt}
+ \item Not all FNs have input capability: clearly they will not
+ be included in the In-Muxing.
