An ePWM module can be synchronized with adjacent ePWM modules. The generated PWM
waveforms are available as outputs on the GPIO pins. Additionally, the EPWM module can
generate ADC starter conversion signals and generate interrupts to the PIE block. External trip
zone signals can trip the output and generate interrupts, too. The outputs of the comparators are
used as inputs to the digital compare sub-module. Next, we will look at the internal details of the
ePWM module.
