Setting P2SEL.x bit together with P2MAPx = PM_ANALOG disables the output driver as well as the input Schmitt trigger.
(4)
Setting the CBPD.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. Selecting the CBx input pin to the comparator multiplexer with the CBx bits automatically disables output driver and input
buffer for that pin, regardless of the state of the associated CBPD.x bit.
