DRV8412: The strange behavior at Fault* pin at the power-up sequency

Part Number:DRV8412

Hi BU team

DRV8412 was designed for the stepper motor application.  Monitored the Fault* pin timing during the powered-up and found an unsmooth rising edge. 

The issues were showed in two below screenshots.

Would you help check it and share your comments?

Thanks
