The individual registers already provide the accumulated energy for each phase, so a simple sum does it.

Thanks for your reply. But the values given out of these registers are 32 bit. I was thinking how do I convert it to the actual value. I think there is some conversion factor.

As per the datasheet(page 58), PMAX = 33,516,139 = 0x1FF6A6B, the instantaneous power computed when the ADC inputs are at full scale. So will dividing the value obtained from the register by Pmax give me the actual wh value ?
