Alternate trigger mode
This mode is selected by programming bits DUAL[4:0] = 01001.
This mode can be started only on an injected group. The source of external trigger comes
from the injected group multiplexer of the master ADC.
This mode is only possible when selecting hardware triggers: JEXTEN must not be 0x0.
Injected discontinuous mode disabled (JDISCEN=0 for both ADC)
1. When the 1st trigger occurs, all injected master ADC channels in the group are
converted.
2. When the 2nd trigger occurs, all injected slave ADC channels in the group are
converted.
3. And so on.
A JEOS interrupt, if enabled, is generated after all injected channels of the master ADC in
the group have been converted.
A JEOS interrupt, if enabled, is generated after all injected channels of the slave ADC in the
group have been converted.
JEOC interrupts, if enabled, can also be generated after each injected conversion.
If another external trigger occurs after all injected channels in the group have been
converted then the alternate trigger process restarts by converting the injected channels of
the master ADC in the group.
