In this mode, the repeater module passes the initial trigger through to the output. As soon as all SOCs configured to receive the trigger are in progress or completed, the repeater issues the trigger again. The process repeats until the configured number of trigger pulses (NSEL + 1) have been issued.
This mode allows the application to easily perform multiple back-to-back samples from a single trigger pulse. When used in conjunction with the aggregation options in the post-processing block, this mode enables oversampling, averaging, or peak detection. Figure 7-130 shows an example of oversampling SOCs generated from a single ePWM trigger.
TRIGGER = ePWM SOCA, NSEL = 3, PHASE = 0, MODE = Oversampling, SPREAD = 0
