K70 Temperature reading - Slopes

I am attempting to read the temperature from the K70 and compute the degrees.

 

The docs mention a warm slope and a cold slope. I have found a slope value in the K70 docs of 1.715 mV/C.

 

I am not sure how this corresponds to the Warm / Cold slope values I should be using in the temp calc. I have looked at AN3031, which addresses the HC08 MPU.

 

The values for the slopes in AN3031 are 1.769 (Warm) and 1.646(cold).

 

Please advise.. or better yet.. if there is a code sample for this computation it would save me time and help me understand the process.

 

thank you!
