Note: The regular trigger selection cannot be changed on-the-fly.
The injected trigger selection can be anticipated and changed on-the-fly. Refer to
Section 21.4.21: Queue of context for injected conversions on page 634
Each ADC master shares the same input triggers with its ADC slave as described in
Figure 97.
Figure 97. Triggers sharing between ADC master and ADC slave
Table 163 to Table 166 give all the possible external triggers of the three ADCs for regular
and injected conversion.
