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.

DTRT

These bits are used to select the data rate.

DTRT[1:0]

Update Rate

26.04 kSPS (CLKIN/3/128)

13.02 kSPS (CLKIN/3/256)

6.51 kSPS (CLKIN/3/512)

3.25 kSPS (CLKIN/3/1024)

VACF

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).
