I am working with ADE7754, i am able to read and write to ADE register meaning my spi communication is working fine. I have connected supply and used input signal conditioning network same as in ADE7754 evaluation board. I have configured ADE for detecting ZCD on all three phases. But i am not getting interrupt and the value in VRMS register is not updating, i.e, VRMS reg value is always same whether connected to supply or not. May be my input is not getting detected at ADE side.

I am not understanding what is going wrong, probably i am missing some silly thing. Any help is appreciable.
