WAVEFORM MODE REGISTER (0x15)
The waveform sampling mode of the ADE7758 is defined by writing to the WAVMODE register. Table 20 summarizes the functionality of
each bit in the WAVMODE register.

Description
These bits are used to select the phase of the waveform sample.
PHSEL[1:0]
These bits are used to select the type of waveform.
WAVSEL[2:0]
These bits are used to select the data rate.
DTRT[1:0]
Setting this bit to Logic 1 switches the VARCF output pin to an output frequency that is
proportional to the total apparent power (VA). In the default state, Logic 0, the VARCF pin outputs
a frequency proportional to the total reactive power (VAR).
