    Hi Kayala,

    If EPWM1A and EPWM1B are coming from 1A and 1B respectively, the software force feature can be used to set the idle state to low. Please refer to the following register for more details

    Are you using the dead band module in active high complementarity mode? If yes, since the deadband module comes after action qualifier you need to use trip zone module make both signals low in idle state.
