(1) Direction controlled by eUSCI_B0 module.
(2) Setting P1SEL1.x and P1SEL0.x will disable the output driver as well as the input Schmitt trigger to prevent parasitic cross currents
when applying analog signals.
(3) Not available on all devices and package types.
(4) Setting the CDPD.x bit of the comparator will disable the output driver as well as the input Schmitt trigger to prevent parasitic cross
currents when applying analog signals. Selecting the CDx input pin to the comparator multiplexer with the CDx bits automatically
disables output driver and input buffer for that pin, regardless of the state of the associated CDPD.x bit
(5) Direction controlled by eUSCI_A0 module.
