Analog-to-digital converter (ADC)

Figure 39. Alternate + Regular simultaneous
If a trigger occurs during an injected conversion that has interrupted a regular conversion, it
will be ignored.
Figure 40. Case of trigger occurring during injected conversion
Combined injected simultaneous + interleaved
It is possible to interrupt an interleaved conversion with an injected event. In this case the
interleaved conversion is interrupted and the injected conversion starts, at the end of the
injected sequence the interleaved conversion is resumed.
using an example.
When the ADC clock prescaler is set to 4, the interleaved mode does not recover with
evenly spaced sampling periods: the sampling interval is 8 ADC clock periods followed by 6
ADC clock periods, instead of 7 clock periods followed by 7 clock periods.
