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 (

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.
Address: 20 (S1), 24 (S2)
Apparent power S1 ( S2 ) is the product of V1
values in the range of 0 ≤ value < 1.0, with the binary point to the right of the MSB.
Address: 21 ( PF1 ), 25 ( PF2 )
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.
Address: 29
These drive the pulse outputs when configured to do so. If the Ichan bit in Modes is “0”, these registers are
driven from P1
