3.2.5 Grouping Channels Together

The ADC channel grouping feature allows users to combine multiple input channels acting as a single sensor connected to the ADC input channel. When the channel group option of the ADPCH register is configured as ADCC ‘channel’, the input channels selected by the ADC Channel Group Selection registers are collectively activated for both analog signal input and a precharge operation. The ADC input is the wire-OR signal from all enabled channels.

The below application example showcases the usage of the ADC Channel Grouping feature.
