PH_AtoC_X
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/NACC + 4.8
0x83
MAINEDGE_X
The number of edge crossings of the selected voltage in the previous
accumulation interval. Edge crossings are either direction and are de-
bounced.

TEMP_RAW
N/A
The filtered, unscaled reading from the temperature sensor.
0x9D
TEMP_X
N/A
This register contains the difference between the die tem-
perature and the reference/calibration temperature as estab-
lished in the TEMP_NOM register, measured in 0.1°C.
0x39
DEGSCALE
21755
Scale factor for the temperature calculation. . It is not ne-
cessary to use values other than the default value.
0x1F
TEMP_NOM
0
This register holds the reference or calibration temperature
vale. At calibration time, the value read in TEMP_RAW must
be written to TEMP_NOM.
0x3A
PPMC
0
Linear temperature correction factor.
0x3B
PPMC2
0
Quadratic temperature correction factor.
Pulse Generation
Table 59 describes the CE pulse generation parameters.
The combination of the PULSE_SLOW and PULSE_FAST parameters 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 de-
rived 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.
Control is transferred to the MPU for pulse generation if EXT_PULSE = 1. In this case, the pulse rate is
determined by APULSEW and APULSER. The MPU has to load the source for pulse generation in
APULSEW and APULSER to generate pulses. Irrespective of the EXT_PULSE status, the output pulse rate
controlled by APULSEW and APULSER is implemented by the CE only. By setting EXT_PULSE = 1, the
MPU is providing the source for pulse generation. If EXT_PULSE is 1, W0SUM_X and VAR0SUM_X are the
default pulse generation sources. In this case, creep cannot be controlled since it is an MPU function.
The maximum pulse rate is 3*FS = 7.5 kHz.
PULSE_WIDTH allows adjustment of the pulse width for compatibility with calibration and other external
equipment. The minimum pulse width possible is 66.16s.
