TMS320F28379D: Shutdown mode for ePWM

Part Number: TMS320F28379D

Hi,

I'm trying to implement a shutdown command for the DSP by stopping the PWM signals at a fault condition. 

I'm using the "AQCSFRC" register to implement this.

EPwm1Regs.AQCSFRC.bit.CSFA = 1;

EPwm1Regs.AQCSFRC.bit.CSFB = 1;

This stops the PWM and keep PWMA at logic low but it keeps the PWMB at logic high.

Is there any other way to overcome this ?

Thank you in advance.
