Analog-to-digital converter (ADC) RM0390
378/1328 RM0390 Rev 4
A JEOC interrupt, if enabled, is generated after all injected ADC2 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.
Figure 86. Alternate trigger: injected group of each ADC
If the injected discontinuous mode is enabled for both ADC1 and ADC2:
• When the 1st trigger occurs, the first injected ADC1 channel is converted.
• When the 2nd trigger occurs, the first injected ADC2 channel are converted
• and so on
A JEOC interrupt, if enabled, is generated after all injected ADC1 channels in the group

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.
