Temp Measurement using Temp Diode in MC33978

The MC33978 / 34978 has a temp diode for measuring junction temperature that can be output on the AMUX.  The data sheet gives a coefficient of 8mV per degree C.  That is the only information that I can find on how to use this feature.  Is this merely a matter of applying a linear equation?  If so what is the slope intercept value?

 

If anyone can supply some guidance here I would greatly appreciate it.

 

Regards,

Tom
