DRV8881: DRV8881P current sense resistors

Part Number:DRV8881

Hi,

I am working on schematic layout of DRV8881 on Altium and I have two questions:

I was wondering what value of current sense resistor should I use and how can I find footprint for sense resistor at Altium? (Pin AISEN and BISEN are connected to sense resistor )

Also, do I have to connect any resistor between pins AVREF and BVREF and V3P3?

Thanks!!
