The EXTSEL[3:0] and JEXTSEL[3:0] control bits select which out of 16 possible events can
trigger conversion for the regular and injected groups.
A regular group conversion can be interrupted by an injected trigger.
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 15.3.21: Queue of context for injected conversions on page 311
Each ADC master shares the same input triggers with its ADC slave as described in
