Direction controlled by eUSCI_B3 module.

Setting P8SEL1.x and P8SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
(4)
Setting the CEPD.q bit of the comparator disables the output driver and the input Schmitt trigger to prevent parasitic cross currents
when applying analog signals. Selecting the C0.q input pin to the comparator multiplexer with the CEIPSEL or CEIMSEL bits
automatically disables the output driver and input buffer for that pin, regardless of the state of the associated CEPD.q bit.
