(2) Setting theCAPD.xbit disables the output driver as well as the input to prevent parasitic cross currentswhenapplying 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.
