Triple ADC mode
•
When the 1st trigger occurs, all injected ADC1 channels in the group are converted.
•
When the 2nd trigger occurs, all injected ADC2 channels in the group are converted.
•
When the 3rd trigger occurs, all injected ADC3 channels in the group are converted.
•
and so on
A JEOC interrupt, if enabled, is generated after all injected ADC1 channels in the group
have been converted.
A JEOC interrupt, if enabled, is generated after all injected ADC2 channels in the group
have been converted.
A JEOC interrupt, if enabled, is generated after all injected ADC3 channels in the group
have been converted.
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 ADC1
channels in the group.

Combined regular/injected simultaneous mode

It is possible to interrupt the simultaneous conversion of a regular group to start the
simultaneous conversion of an injected group.
Note: In combined regular/injected simultaneous mode, one must convert sequences with the
same length or ensure that the interval between triggers is longer than the long conversion
time of the 2 sequences (Dual ADC mode) /3 sequences (Triple ADC mode). Otherwise, the
