Thank you Rick
I Known DRV8812EVM DAC mode to drive drive Stepper motor but in my sch I use PWM mode to to drive Stepper motor. I found if pin23 20 input fixed PWM （Frequency any period are all not change ）but out put pin have same uncertain 1-2us timer delay with input. How it happen, i test other drive like drv8841 input wave and output wave are same not delay
