Channel #0 in-place comparator function description
The in-place comparator of Channel #0 has four sets of compare input sources for selection,
and they are the position counter values for axes #0, #1, #2, and #3. The output interface also
provides four sets of output interfaces for selection, and they are CMOS3.3V output, DO output
of each axis (24V), axis #3 RS422 DIR single serial output, and axis #3 RS422 dual serial output
at the same time (as shown in Figure 3.1.4.2).

Note: in the output selection function interface, you can only select
one channel for output. This means you cannot assign Channel #0
and Channel #1 at the same time for different signal output.
