Set up input channels 0,1 muxes in the same way as for the channels 2-7
later in the code.

Can a wording variant like “Set input channels “0,1 muxes” up …”
be a bit nicer?
(Is there a need to adjust any comments in the source code accordingly?)


Would you like to avoid empty descriptions according to addresses
