ePWM modules can be chained together via a clock synchronization scheme that allows them to operate as a single system when required. In the synchronous mode of operation, it is critical to check the proper synchronization of the various PWM instances to avoid catastrophic conditions. The synchronization of the various PWMs can be checked by reading the TBSTS.SYNCI bit of ePWM module. The proper phase relationship intended as a result of the sync operation can be cross-checked by comparing the TBCTR register value.
