5.5 Pulse-Rate Register
Address: 6
Default** = 32000.00Hz
The Pulse-Rate Register determines the frequency of the train of pulses output on the EOUT pin. Each EOUT
pulse represents a predetermined magnitude of real (billable) energy. The register’s smallest valid value is 2
-4
but can be in 2
-5
increments.
5.6 I,V,P,E Signed Output Register Results
Address: 7 - 10
These signed registers contain the last value of the measured results of I, V, P, and E. The results are in the
range of -1.0
I, V, P, E
<
1.0. The value is represented in two's complement notation, with the binary point
place to the right of the MSB (which is the sign bit). I, V, P, and E are output results registers which contain
signed values. Note that the I, V, and P Registers are updated every conversion cycle, while the E Register is
only updated after each computation cycle. The numeric format of this register is two’s complement notation.

Unsigned Output Register Results
Address: 11,12
These unsigned registers contain the last value of the calculated results of I
RMS
and V
RMS
. The results are in
the range of 0.0
I
RMS
,V
RMS
<
1.0. The value is represented in binary notation, with the binary point place to
the left of the MSB. I
RMS
and V
RMS
are output result registers which contain unsigned values.
5.8 Timebase Calibration Register
Address: 13
Default** = 1.000
The Timebase Calibration Register is initialized to 1.0 on reset, allowing the device to function and perform com-
putations. The register can be loaded with the clock frequency error to compensate for a gain error caused by
the crystal/oscillator tolerance. The value is in the range 0.0
TBC
<
2.0.
