2. X: Don’t care.
3. Setting the CAPD.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. Selecting the CAx input pin 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.
