on page 12 of AN-1171 ADE7880 calibration note, the Error calculation need AWATTHR and AVARHR. As corrected by Hmani in here:

AVARHR should be replaced by AFVARHR.

Question then, How about AWATTHR? Should it be replaced by AFWATTHR?

AWATTHR reading is not equal to AFWATTHR reading(huge difference) in my case, although I input line frequency component only to my board.
