STOP
Terminates the auto-boot sequence.
0 = Normal (default)
1 = Stop sequence
INTOD
Converts INT output pin to an open drain output.
0 = Normal (default)
1 = Open drain
NOCPU
Saves power by disabling the CPUCLK pin.
0 = Normal (default)
1 = Disables CPUCLK
NOOSC
Saves power by disabling the crystal oscillator.
0 = Normal (default)

The Harmonic Active Power (PH) is calculated by subtracting the Fundamental Active Power from the Active
(Real) Power. The value is represented in two's complement notation and in the range of -1.0 ≤ PH < 1.0, with
the binary point to the right of the MSB.

The Fundamental Active Power (PF) is calculated by performing a discrete Fourier transform (DFT) at the rele-
vant frequency on the V and I channels. The results are multiplied to yield fundamental power. The value is rep-
resented in two's complement notation and in the range of -1.0 ≤ PH < 1.0, with the binary point to the right of
the MSB.
