ADC0 includes analog multiplexer circuitry with independent selection capability for the AIN+ and AIN-
inputs. Each input can be connected to one of ten possible input sources: AIN0.0 though AIN0.7, AGND, or
the on-chip temperature sensor circuitry (Figure 5.26). The ADC0MUX register (Figure 5.27) controls the
input mux selection for both input channels. The multiplexer configuration allows for measurement of sin-
gle-ended or differential signals. A single-ended measurement can be performed by connecting one of the
ADC inputs to AGND. Additionally, the temperature sensor can be measured in single-ended or differential
mode. The temperature sensor is automatically enabled when it is selected with the ADC multiplexer. See
