1. The CRC code is there purely to provide reassurance that the calibration data has not been accidentally overwritten. The concept is that the user calculates the CRC over the calibration words (using, for example, the sample code provided in RFMicron’s Reading Magnus-S Sensors App Note), and then compares the calculated value to the value stored on the temperature sensor tag. If they match, then the calibration data has not been altered. However, if the user is confident that the calibration data has not been unintentionally modified, then there is no harm in simply ignoring the CRC code.
2. The “C” value in the referenced formula is the Temperature Code that you want to convert to degrees C.
