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.
4.3.10 Other CE Parameters
Table 66 shows the CE parameters used for suppression of noise due to scaling and truncation effects.
The table also includes the parameter which indicates the CE Code version.

Description
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 el-
ement 0 and 1 to compensate for input noise and truncation.

These parameters are added to the VAR calculation for el-
ement A and B to compensate for input noise and truncation.

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”.
These locations are overwritten in operation.
4.3.11 CE Flow Diagrams
Figure 41 through Figure 43 show the data flow through the CE in simplified form. Functions not shown
include delay compensation, sample interpolation, scaling and processing of meter equations.
