Figure 1-3 shows more internal details of a single ePWM module. The main signals used by the ePWM module are:
∙PWM output signals (EPWMxA and EPWMxB).
The PWM output signals are made available external to the device through the GPIO peripheral described in the system control and interrupts guide for your device.
∙Trip-zone signals (TZ1 to TZ6).
These input signals alert the ePWM module of an external fault condition. Each module on a device can be configured to either use or ignore any of the
∙
The synchronization signals daisy chain the ePWM modules together. Each module can be configured to either use or ignore its synchronization input. The clock synchronization input and output signal are brought out to pins only for ePWM1 (ePWM module #1). The synchronization output for ePWM1 (EPWM1SYNCO) is also connected to the SYNCI of the first enhanced capture module (eCAP1).
∙ADC start-of-conversion signals (EPWMxSOCA and EPWMxSOCB).
Each ePWM module has two ADC start of conversion signals (one for each sequencer). Any ePWM module can trigger a start of conversion for either sequencer. Which event triggers the start of conversion is configured in the
