Bits 4:0 – MUXPOS[4:0]: Positive MUX Input Selection

Positive MUX Input Selection

These bits define the MUX selection for the positive ADC input. If the internal bandgap voltage or temperature sensor input channel is selected, then the Sampling Time Length bit group in the Sampling Control register must be written with a corresponding value.
