We are using these devices in multiple energy meter designs. They continuously sample V, I, Watts and VA using a mircocontroller which reads those values from the SPI port based in the device IRQ. I now need to be able set up a mode where I collect values from the Waveform registers of these ADE devices. What is not clear to me from the spec is,
How fast (often) will I need to read the Waveform register in order to get every sample, so that none are overwritten and lost?
Does changing the sample rate change the frequency with which I would need to be able to read the Waveform register?
