Mov C,P2.1 ; move whatever on P2.1 to carry is there any initialization required (i.e latch register bit set ) ... how to do that ..any help in that regard >> The digital GND is not connected ADE7756 is properly grounded and uC has also been grounded properly and as ther are on 2 different board using 2 different power supplied so i have also made the gorund common >>The digital VDD has been left open i didnt get what it means ?? >> The AGND and DGND pins are connected in a way that there is an unaceptable differential voltage between these pins.
