31.2.6 AUTO-CONVERSION TRIGGER
The Auto-conversion Trigger allows periodic ADC mea-
surements without software intervention. When a rising
edge of the selected source occurs, the ADGO bit is set
by hardware.
The Auto-conversion Trigger source is selected with
the ADACT<4:0> bits of the ADACT register.
Using the Auto-conversion Trigger does not assure
proper ADC timing. It is the user’s responsibility to
ensure that the ADC timing requirements are met. See
Table 31-2 for auto-conversion sources.
