Output variables: TEMP_X is the temperature measurement from reference temperature of TEMP_NOM. TEMP_X is
computed using TEMP_RAW_X and DEGSCALE. This quantity is positive when the temperature is above the reference and is
negative for cold temperatures.
TEMP_RAW_X is the raw processed value from ADC output and is the fundamental quantity for temperature measurement.
TEMP_RAW_X is less than TEMP_NOM at higher temperatures. TEMP_RAW_X is more than TEMP_NOM for cooler
temperatures than reference temperature.
GAIN_ADJ is a scaling factor for power measurements based on temperature (when in internal temperature compensation
mode). In general, for higher temperatures it is lower than 16384 and higher than 16384 for lower temperatures. GAIN_ADJ is
mainly dependent on the PPMC, PPMC2 and TEMP_X register values. This parameter is automatically computed by the CE
and is used by the CE for temperature compensation.

Scales all voltage and current inputs. 16384 provides unity gain. Default is
16384. If EXT_TMP = 0, GAIN_ADJ is updated by the CE.

Description
During calibration, the value of TEMP_RAW_X should be placed in
TEMP_NOM.
Scale factor for TEMP_X.
TEMP_X = -DEGSCALE*2
Should be 15 or 0. When 15, causes the CE to ignore internal temperature
compensation and permits the MPU to control GAIN_ADJ. When internal
temperature compensation is selected, GAIN_ADJ will be:
Default is 0 (internal compensation).
Linear temperature compensation factor. Equals the linear temperature co-
efficient (PPM/°C) of VREF multiplied by 26.84, or TC1 (expressed in µV/°C,
see Electrical Specifications) multiplied by 22.46

I and will therefore have a double effect on products.
