Hi everyone!

I'm building an power meter based on ADE7978(1 pcs) and ADE7932(4 pcs) chipset. The four ADE7932 respectively used for collecting A/B/C phase voltage current and voltage current, an independent respectively from ADE7978 DATA_A/DATA_B/DATA_C/DATA_N. I read AVRMS BVRMS/CVRMS register values are correct, but read NVRMS register values is not normal. You can determine the received DATA_N ADE7932 is normal, but why it is wrong to read data from the NVRMS is unknown. Please give me a solution, thank you!
