DRV8308: Control loop

Part Number: DRV8308

Hi Experts, 

I have few questions on the DRV8308 

1. May I know if there is current closed loop built in the driver? If yes, which parameter is for user to adjust based on the motor?
2. Is it possible to share the control diagram of the current and/or velocity loop? It may help us to locate the parameters for the tuning.

Best Regards
