What is the KL17 temperature slope value?

[tonymakkiel]

Hi,

What are the cold and hot temperature slope value for KL17 mentioned in the reference manual (23.5.8)?  In the example code (adc_low_power_twrkl43z48m) a different equation seem to be used.

Temperature = 25 - (ADCR_T - ADCR_TEMP25) * 100 / ADCR_100M

The above equation will always return negative value.  Should it be

Temperature = 25 - ((ADCR_T - ADCR_TEMP25) / ADCR_100M)

?

Many Thanks,

Tony

You can find the Temp sensor slope on the data sheet, please also use the AN3031 for reference
