DRV8889-Q1: Question on OCP and fault action

Hi team

From my understanding for brush DC driver the OCP usually use to limit the inrush current during startup. For stepper motor driver which use current control, when does OCP usually happens? If OCP for thousands of time, will our IC degrade?

For the fault action like latch or auto-retry, can it be configured through SPI when output availble? Or it needs to be configured with output disabled? 

Thank you
