CCS/TMS570LC4357: The ETPWM module creates a continuous and repeating signal, but how can I create a signal with a specific frequency that only pulses twice then flatlines?

I'm aware that I can manually code a pin to activate, then use a delay function in CCS, but I believe I heard that there is a bit of inaccuracy in this method

Hello,

PWM module generate a sequence of waveform rather than just one pulse. But you can TZ (trip-zone) to pull the PWM pin to LOW to HIGH. Please refer to trip zone section in TRM.
