TMS320F28377D: Ways to turn off all the EPWM outputs (to high, low or HZ)

Sheldon He

Part Number: TMS320F28377D

Hi expert,

Could you let me know if there are better ways to "turn off all the EPWM" (output goes to a dedicated state) on F28377D. Currently we have tried AQCFRC and TZFRC but the turn off is not simultaneous.

Do you have better solutions here?

Thanks

You can use an "UNUSED" or "UNBOUNDED" GPIO, as an output. Route that signal to INPUT XBAR, use that for a TRIP, turn all epwm outputs to a state which your system requires.
