(2) Setting P9SEL1.x and P9SEL0.x disables the output driver and the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
(3) 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.
(4) Depending on the configuration of the ESI module, other ESICI2/ pins are used, and thus should have the input Schmitt triggers
disabled (with P9SEL1.x = 1 and P9SEL0.x = 1) and cannot be used as digital I/O, ADC, or comparator inputs.
