Temperature Measurement and Temperature Compensation
Input variables: TEMP_NOM is the reference value for temperature measurement, i.e. when this value is set with
TEMP_RAW_X at known temperature. The 71M6513/6513H measures temperature with reference to this value.
DEGSCALE is the slope or rate of temperature increase or decrease from the TEMP_NOM for TEMP_X measurement.
PPMC and PPMC2 are temperature compensation coefficients. Their values should reflect the characteristics of the band gap
voltage reference of the chip. PPMC and PPMC2 follow the square law characteristics to compensate for nonlinear temperature
behaviors, when the 71M6513/6513H is in internal temperature compensation mode.
EXT_TEMP allows the MPU to select between direct control of GAIN_ADJ or management of GAIN_ADJ by the CE, based on
TEMP_X and the temperature correction coefficients PPMC and PPMC2.
