Hi,
HRPWM example 9 generates the following function:
void EPWM_init(){

HRPWM_setActionQualifierAction(myEPWM1_BASE, EPWM_AQ_OUTPUT_B, EPWM_AQ_OUTPUT_NO_CHANGE, EPWM_AQ_OUTPUT_ON_TIMEBASE_DOWN_CMPA);
HRPWM_setActionQualifierAction(myEPWM1_BASE, EPWM_AQ_OUTPUT_B, EPWM_AQ_OUTPUT_HIGH, EPWM_AQ_OUTPUT_ON_TIMEBASE_UP_CMPB);
HRPWM_setActionQualifierAction(myEPWM1_BASE, EPWM_AQ_OUTPUT_B, EPWM_AQ_OUTPUT_LOW, EPWM_AQ_OUTPUT_ON_TIMEBASE_DOWN_CMPB);
HRPWM_setDeadBandDelayPolarity(myEPWM1_BASE, EPWM_DB_FED, EPWM_DB_POLARITY_ACTIVE_LOW);
HRPWM_setDeadBandDelayMode(myEPWM1_BASE, EPWM_DB_RED, true);

HRPWM_setMEPEdgeSelect(myEPWM1_BASE, HRPWM_CHANNEL_A, HRPWM_MEP_CTRL_RISING_AND_FALLING_EDGE);
HRPWM_setCounterCompareShadowLoadEvent(myEPWM1_BASE, HRPWM_CHANNEL_A, HRPWM_LOAD_ON_CNTR_ZERO_PERIOD);
HRPWM_setMEPEdgeSelect(myEPWM1_BASE, HRPWM_CHANNEL_B, HRPWM_MEP_CTRL_RISING_AND_FALLING_EDGE);
HRPWM_setCounterCompareShadowLoadEvent(myEPWM1_BASE, HRPWM_CHANNEL_B, HRPWM_LOAD_ON_CNTR_ZERO_PERIOD);
HRPWM_enablePeriodControl(myEPWM1_BASE);
...
...
same for PWM2, PWM3 and PWM4
}
The line in red seems a mix up. Shouldn't it be "HRPWM_setFallingEdgeDelayCountShadowLoadMode()" or use "EPWM_DB_INPUT_EPWMA"?
I use C2000Ware_5_04_00_00. CCS V20.1.1.8__1.7.1
