(2) Setting P3SEL1.x and P3SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
(3) Setting the CEPDx bit of the comparator disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals. Selecting the Cx input pin to the comparator multiplexer with the input select bits in the comparator module
automatically disables output driver and input buffer for that pin, regardless of the state of the associated CEPDx bit.
