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

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 * 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.
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.
