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.
