DRV8350R: DRV8350 RT/SD pin question

Part Number: DRV8350R
Other Parts Discussed in Thread: DRV8350, LM5008A

HI Team, 

In DRV8350 datasheet 7.1, the abs of RT/SD pin is -0.3 ~ 7V. 

But in the figure 63, we connect this pin to VM via a resistor R_RT/SD. And in table 20, the example value of VM is 48V. How can we guarantee that the actual voltage on this pin is below 7V? How should we calculate the right resistor value? Thanks.
