Hello Mahmoud,

There are multiple ways you could SW force your EPWM. You can refer to epwm.h file what fits best for you.

A simple example for AQ continuous SW force action:

EPWM_setActionQualifierContSWForceAction(uint32_t base,

EPWM_ActionQualifierOutputModule epwmOutput,

EPWM_ActionQualifierSWOutput output)

(or)

for one-time SW force action:

EPWM_setActionQualifierSWAction(myEPWM1_BASE, EPWM_AQ_OUTPUT_A, EPWM_AQ_OUTPUT_LOW);

Best,

and if i want to turn it back on i should replace EPWM_AQ_OUTPUT_LOW with EPWM_AQ_SW_DISABLED ?

Yes, using the EPWM_AQ_SW_DISABLED you can disable the SW logic.
