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 device specification for availability and connectivity of ETRIG3-
0 inputs. If a particular ETRIG3-0 input option is not available, writing a 1 to ETRISEL only sets the bit but has
not effect, this means that one of the AD channels (selected by ETRIGCH3-0) is configured as the source for
external trigger. The coding is summarized in
A/D Resolution Select — These bits select the resolution of A/D conversion results. See
coding.
Discharge Before Sampling Bit
0 No discharge before sampling.
1 The internal sample capacitor is discharged before sampling the channel. This adds 2 ATD clock cycles to
External Trigger Channel Select — These bits select one of the AD channels or one of the ETRIG3-0 inputs
as source for the external trigger. The coding is summarized in

the sampling time. This can help to detect an open circuit instead of measuring the previous sampled
channel.
If only AN0 should be converted use MULT=0.
