(1) X = Don't care
(2) Direction controlled by eUSCI_A1 module.
(3) Setting P2SEL1.x and P2SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
(4) Setting the CEPD.x 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 CEPD.x bit.
