Peak current, I1 PEAK ( I2 PEAK ) and peak voltage, V1 PEAK ( V2 PEAK ) are the instantaneous current and voltage
samples with the greatest magnitude detected during the last low-rate interval. These are two's complement
values in the range of -1.0 ? value ? 1.0, with the binary point to the right of the MSB.

Apparent power S1 ( S2 ) is the product of V1 RMS and I1 RMS ( V2 RMS and I2 RMS ), These are two's complement
values in the range of 0 ? value ? 1.0, with the binary point to the right of the MSB.

Power factor is calculated by dividing active power by apparent power. The sign is determined by the active
power sign. These are two's complement values in the range of -1.0 ? value ? 1.0, with the binary point to the
right of the MSB.

T contains results from the on-chip temperature measurement. By default, T uses the Celsius scale, and is a
two's complement value in the range of -128.0 ? value ? 128.0 ( o C), with the binary point to the right of bit 16.
T can be rescaled by the application using the T GAIN and T OFF registers.
