DRV8711: The stall detecting voltage by setting SDTHR

Part Number: DRV8711

Hi,

I have a question about the detecting voltage by setting SDTHR.
We need to adjust SDTHR register at using internal stall detection function.
SDTHR register has the resolution of 0x40.

How much detecting voltage does SDTHR=0x40 mean?
and
How much detecting voltage does SDTHR=0x20 mean?

I think that the detecting voltage is voltage value of divided internal ref voltage by SDTHR register.

Is it correct? 

Best regards,
Shimizu
