I have also some important questions about energy :
1- how can I to find true value if I don't use a line cycle active energy accumulation ?
2- could you please give me information about which registers should I configure in the both methods of accumulation ?
for example WTHR0 and WTHR1 etc.
3- in line cycle accumulation, If I understood its logical, AWATTHR is updated automatically every period (period = accumulation time. Is it right ? ). please if I'm right, could you give a method how can I manage the communication between my micro-controller and ADE7878a. (should I use the interrupt for synchronizing the communication and catch every energy value respecting the accumulation time or what ? )
thank you in advance for your reply.
