HYWATT, HYVAR, HYVA, HZWATT, HZVAR and HZVA 24-
bit signed registers. Figure 61 presents the associated data path.
The power factor of the fundamental component is stored into
FPF 24-bit signed register. The power factors of the 3 harmonic
components are stored into HXPF, HYPF and HZPF 24-bit
signed registers.

The total harmonic distortion plus noise ratios computed using
the rms of the fundamental components and the rms of the
phase current and the phase voltage (see Root Mean Square
Chapter for details about these measurements) are stored into
VTHDN and ITHDN 24-bit registers in 3.21 signed format.
This means the ratios are limited to +3.9999 and all greater
results are clamped to it.
