TMS320F280039C: Software Sync initialization when using HRPWM

Part Number: TMS320F280039C


Hi Team,

In the TRM for F28003x, there is a note 'When EPWMxSYNCI is EPWMxSYNCO source, a software synchronization pulse should be issued only once during high-resolution period initialization. If a software sync pulse is applied while the PWM is running, the jitter will appear on the PWM output at the time of the sync pulse.'

However, in case of processors F28003x/28002x and F2838x, we do not have EPWMxSYNCI as source for EPWMxSYNCO but we have SWEN which is basically passing through the Software sync signal. Does this mean that, the above note should be 'When SWEN is EPWMxSYNCO source, a software synchronization pulse should be issued only once during high-resolution period initialization?'
