DRV8301: The GVDD issue for DRV8301

Part Number:DRV8301

Hi team,

The customer uses DRV8301. He read the Status Register 1 and the Status Register 2 using SPI.

The value of  the Status Register 1 is jumped between 0 and 0x600. The value of  the Status Register 2 is 0x801.

Then he measures the voltage of the GVDD pin. It is 10.6V. The datasheet shows the GVDD voltage range is 8V~16V. 

So, I think 10.6V is fine. But why the value of the Status Register 1 is shown the GVDD is fault. 

Would you explain this?
