Hi, my application is to detect voltage surges & sags using ADE 7758.
After referring the data-sheet, I am having a couple of queries regarding the same.
Regarding the voltage sampling, WFORM register holds the value of the voltage sampled from the ADC.
Again, the PHSEL[1:0] bits determines the phase from which the sample are routed. This means that WFORM register holds only the voltage value of the selected phase.
So, to read voltage from different phases, are we supposed to follow a cyclic pattern like
select phase a
select phase b
select phase c
