The ADC module includes external trigger inputs ETRIG0, ETRIG1, ETRIG2, and ETRIG3. The external
trigger allows the user to synchronize ADC conversion to external trigger events.

Whenever the ADC’s Special Channel Conversion Bit (SC) is set, it is capable of running conversion on a
number of internal channels (see
connected to these special conversion channels.
