- Double-click on your Target Preferences block.
- Go to the "Peripherals" tab -> ePWM.
- Select a Pin for the SYNCI. You have the choice between GPIO 6 and 32, pick what suits your hardware design.
- Click OK.Now, a rising edge on the GPIO you selected will drive a synchronization pulse to the ePWM1 module.
- Double click on your ePWM block, make sure ePWM1 is selected for the module.
- On the "General" tab, go to "Phase offset source" and select "Specify via dialog". The "Phase offset value" will be passed to the ePWM1 timer on each rising edge of your SYNCI signal. You can keep the "Phase offset value" as zero.
