Power Application Controller
The auto-sampling sequencer can interrupt the microcontroller when either conversion sequence is finished.
13.2.3. EMUX Control
A dedicated low latency interface controllable by the auto-sampling sequencer or register control allows
changing the ADC premultiplexer and asserting/deasserting the S/H circuit in the configurable analog front end,
allowing back to back conversions of multiple analog inputs without microcontroller interaction.
