Fault, Warning Reporting and Handling in DRV8301

Hi,

I am experimenting with PMSM and DRV8301-HC-C2-Kit.  The kit goes into fault mode if the motor speed crosses 175rpm and also if the load crosses 10Kgf.  How to know the reason for this fault. 

Datasheet Page16 mentions of various report handling thru SPI.  I checked the SPISTS register and it displays 0x0000.  How to capture the fault condition i.e., over current over temperature etc?.

Pl suggest

thx
