I and V contain the instantaneous measured values for current and voltage, respectively. The instantaneous
voltage and current samples are multiplied to obtain Instantaneous Power (P). The value is represented in two's
complement notation and in the range of -1.0 ? I, V, P ? 1.0, with the binary point to the right of the MSB.

The instantaneous power is averaged over each computation cycle (N conversions) to compute Active Power
(P Active ). The value will be within in the range of -1.0 ? P Active ? 1.0. The value is represented in two's complement
notation, with the binary point to the right of the MSB.

I RMS and V RMS contain the Root Mean Square (RMS) values of I and V, calculated each computation cycle. The
value is represented in unsigned binary notation and in the range of 0.0 ? I RMS , V RMS ? 1.0, with the binary point
to the left of the MSB.

Epsilon ( ? ) is the ratio of the input line frequency to the sample frequency of the ADC (See Section 5.4 Perform-
ing Measurements on page 16). Epsilon is either written to the register, or measured during conversions. The
