BOOSTXL-DRV8305EVM: Current scaling

$

Part Number:BOOSTXL-DRV8305EVM

I am using LauncpadXL 28379D + DRV8305EVM.

DRV8305, Gain is 10 V/V, Rshunt resistance is 0.007 ohm (DRV8305EVM) .

max input current, +19.3 A = 3 V from DRV 8305

Input current, 0A = 1.65 V from DRV 8305

What is the max negative current read by DRV8305?

What is the voltage output of DRV 8305 at its max negative current? 

I need this information for calibrating the current. I am little confused over here. I want to clarify myself. Thanks.
