External Trigger Source Select — This bit selects the external trigger source to be either one of the AD
channels or one of the ETRIG3–0 inputs. See the device overview chapter for availability and connectivity of
ETRIG3–0 inputs. If ETRIG3–0 input option is not available, writing a 1 to ETRISEL only sets the bit but has
not effect, that means still one of the AD channels (selected by ETRIGCH2–0) is the source for external trigger.
The coding is summarized in

as source for the external trigger. The coding is summarized in
ETRIGSEL
Only if ETRIG3–0 input option is available (see device overview chapter), else ETRISEL is
ignored, that means external trigger source is still on one of the AD channels selected by
