(1) X = Don't care
(2) Setting the P6SEL.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals.
(3) The ADC12_A channel Ax is connected internally to AV_SS if not selected via the respective INCHx bits.
(4) X = Don't care
