Protection inside TMC5130A-TA

Hi,

    I'm planning to use TMC5130A-TA in my product to drive 24V stepper motor with 2A current required per coil. My question is if someone rotates the stepper motor manually when device is off the stepper motor will generate the back emf and force the current in the driver pins. Now will it damage the driver. Does driver has protection inside for such back emf generated ?

Or do I need to connect something externally to protect the driver. Please suggest what and how to connect externally.

Regards,
