Description
Kh =
VMAX ? IMAX ? K
WRATE ? N ACC ? X
? Wh / pulse
where:
K = 66.1782 (Local Sensors)
0x21
WRATE
547
K = 109.1587 (Remote Sensor)
K = 47.1132 (ce41a04 and Local Sensors)
N ACC = 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 ).

Scale factor for VAR measurement.
SUM_SAMPS (N ACC ).
Wh pulse (WPULSE) generator input to be updated by the MPU
when using external pulse generation. The output pulse rate is:
0x45
APULSEW
0
APULSEW * F S * 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.

WPULSE counter.
Unsigned numerator, containing a fraction of a pulse. The value
in this register always counts up towards the next pulse.
Roll-over accumulator for WPULSE.
VARh (VPULSE) pulse generator input.
VPULSE counter.
Unsigned numerator, containing a fraction of a pulse. The value
in this register always counts up towards the next pulse.
