where:
K = 66.1782 (Local Sensors)
K = 109.1587 (Remote Sensor)
NACC = SUM_SAMPS[12:0] (CE RAM 0x23)
See Table 83 for the definition of X.
The default value yields 1.0 Wh/pulse for VMAX = 600 V and
IMAX = 208 A. The maximum value for WRATE is 32,768 (2
15).
0x22
KVAR
6444
Scale factor for VAR measurement.
0x23
SUM_SAMPS
2520
SUM_SAMPS (NACC).
0x45
APULSEW
0
Wh pulse (WPULSE) generator input to be updated by the MPU
when using external pulse generation. The output pulse rate is:
APULSEW * FS * 2
-32 * WRATE * X * 2-14.
This input is buffered and can be updated by the MPU during a
conversion interval. The change takes effect at the beginning of
the next interval.
0x46
WPULSE_CTR
0
WPULSE counter.
0x47
WPULSE_FRAC
0
Unsigned numerator, containing a fraction of a pulse. The value
in this register always counts up towards the next pulse.
0x48
WSUM_ACCUM
0
Roll-over accumulator for WPULSE.
0x49
APULSER
0
VARh (VPULSE) pulse generator input.
0x4A
VPULSE_CTR
0
VPULSE counter.
0x4B
VPULSE_FRAC
0
Unsigned numerator, containing a fraction of a pulse. The value
in this register always counts up towards the next pulse.
0x4C
VSUM_ACCUM
0
Roll-over accumulator for VPULSE.
