Temperature Parameters
MAINEDGE_X is useful for implementing a real-time clock based on the input AC signal. MAINEDGE_X is the number of half-
cycles accounted for in the last accumulated interval for the AC signal.
TEMP_RAW may be used by the MPU to monitor chip temperature. Temperature compensation is implemented by the CE,
based on the value written to TEMP_NOM .

Description
Filtered, unscaled reading from the temperature sensor.
Reference temperature for temperature compensation.
Multiplier for temperature calculation.
Scales all voltage and current inputs, based on the temperature
compensation mechanism. 16384 provides unity gain.
Linear parameter for temperature compensation.
Quadratic parameter for temperature compensation.
GAIN_ADJ is a scaling factor for measurements based on the temperature. GAIN_ADJ is controlled by the MPU for
temperature compensation.
