2.8.1 Operational Overview of the Event-Trigger Submodule
www.ti.com Event-Trigger (ET) Submodule
The following sections describe the event-trigger submodule's operational highlights.
Each ePWM module has one interrupt request line connected to the PIE and two start of conversion
signals (one for each sequencer) connected to the ADC module. As shown in Figure 2-39 , ADC start of
conversion for all ePWM modules are ORed together and hence multiple modules can initiate an ADC
start of conversion. If two requests occur on one start of conversion line, then only one will be recognized
by the ADC.
