If FREQSEL1/FREQSEL0 select phase A: Phase lag from A to B.
If FREQSEL1/FREQSEL0 select phase B: Phase lag from B to C.
If FREQSEL1/FREQSEL0 select phase C: Phase lag from C to A.
The angle in degrees is (0 to 360): PH_AtoB_X * 360/N ACC + 2.4
If FREQSEL1/FREQSEL0 select phase A: Phase lag from A to C.
If FREQSEL1/FREQSEL0 select phase B: Phase lag from B to A.
If FREQSEL1/FREQSEL0 select phase C: Phase lag from C to B.
Angle in degrees is (0 to 360): PH_AtoC_X * 360/N ACC + 4.8
The number of edge crossings of the selected voltage in the
previous accumulation interval. Edge crossings are either
direction and are debounced.
The output of the battery measurement. This value is
equivalent to twice the measured ADC value.

Description
The filtered, unscaled reading from the temperature sensor.
This register contains the difference between the die temperature
and the reference/calibration temperature as established in the
TEMP_NOM register, measured in 0.1°C.
Scale factor for the temperature calculation. It is not necessary
to use values other than the default value.
This register holds the reference or calibration temperature
vale. At calibration time, the value read in TEMP_RAW must be
written to TEMP_NOM.
Linear temperature correction factor.
Quadratic temperature correction factor.
5.3.10 Pulse Generation
Table 64 describes the CE pulse generation parameters.
The combination of the PULSE_SLOW and PULSE_FAST parameters (see Table 58) controls the speed of
the pulse rate. The default values of 0 and 0 will maintain the original pulse rate given by the Kh equation.
WRATE controls the number of pulses that are generated per measured Wh and VARh quantities. The
lower WRATE is, the slower the pulse rate for measured energy quantity. The metering constant Kh is
derived from WRATE as the amount of energy measured for each pulse. That is, if Kh = 1Wh/pulse, a
power applied to the meter of 120 V and 30 A results in one pulse per second. If the load is 240 V at
150 A, ten pulses per second will be generated.
