(1) X = don't care
(2) Default after reset (PUC/POR)
(3) Setting theCAPD.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currentswhen 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.
