The AFE contains two 9-to-1 analog multiplexers which are used to select the source connected to the positive input (INP) and negative input (INM) of the ADC. Each step can be configured, via the respective ADC_STEPCONFIG_j register, to select the appropriate input sources. For more information, refer to Section 12.1.1.4.2.1 and the ADC_STEPCONFIG_j register field descriptions.
