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.
