(2) Setting the CAPD.x bit disables the output driver as well as the input to prevent parasitic cross currents when applying analog signals.
Selecting the CAx input to the comparator multiplexer with the P2CAx bits automatically disables the input buffer for that pin, regardless
of the state of the associated CAPD.x bit.
