27.3.20 ADC triggers
The ADCs can be triggered by the master and the 6 timing units.
10 independent triggers are available for both the regular and the injected sequencers of the
ADCs. The external events can be used as triggers. They are taken right after the
conditioning defined in the HRTIM_EECRx registers, and are not depending on the EEFxR1
and EEFxR2 register settings.
Up to 32 events can be combined (ORed) for ADC triggers 1 to 4, in HRTIM_ADC1R to
HRTIM_ADC4R registers, as shown on Figure 251. The ADC triggers 1/3 and 2/4 are using
the same source set. A multiple triggering is possible within a single switching period by
selecting several sources simultaneously. A typical use case is for a non-overlapping
multiphase converter, where all phases can be sampled in a row using a single ADC trigger
output.
