This register contains the reference point for the temperature
measurement. At calibration temperature, the value read at
TEMP_RAW_X should be written to TEMP_NOM. The CE will calculate
the chip temperature TEMP_X relative to the reference temperature.
The scale factor for the temperature calculation. It is not necessary
to use values other than the default value.
PHADJ
PHADJ
This is the scale factor for the VAR calculation. No value
other than the default value should be applied.
These parameters are added to the Watt calculation for
element 0 and 1 to compensate for input noise and truncation.
These parameters are added to the VAR calculation for
element A and B to compensate for input noise and truncation.
These parameters are added to compensate for input noise
and truncation in their respective channels in the squaring
calculations for I
Text strings holding the CE version information as supplied
by the CE data associated with the CE code. For example,
the words 0x63653331 and 0x61303463 form the text string
“ce31a04c”.
