Where does the phase voltage datapath divert to another phase when using VTOIx? It looks like it is after the xPHCAL input from figure 40, Phase Voltages Used in Different Datapaths, of the ADE7878 datasheet but how far after? Is it before or after the zero crossing detection? I am planning to use the Voltage vs Current time delay measurements in the ANGLEx registers and use VTOIx to overcome PCB layout issues. Where would the datapath change be on Figure 4, ADE7878 Functional Block Diagram, of the ADE7878 data sheet?
