(1) Setting P1SEL1.x and P1SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when

applying analog signals.

(2) Not available on all devices and package types.

(3) Setting the CDPD.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 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.
