The repeater module determines when to re-trigger based on the values of ADCSOCxCTL.TRIGSEL and the SOC flags in ADCSOCFLG1. A repeat trigger is issued when all SOCs configured to be triggered by the repeater module instance are no longer pending. Figure 18-10 describes the trigger repeat logic. Because the SOC pending flag goes low at the end of the sample and hold phase, the module has plenty of time to re-trigger conversions without introducing any latency between repeat conversions.
If the ADC is in burst mode, and the repeater is selected as the BURSTTRIG source, then the repeater fires a re-trigger pulse whenever there are no high-priority associated SOCs pending, and there are no round-robin SOCs pending.
