Low-Power, Active Energy, Polyphase AFE
This signed register contains the real accumulated energy delivered into phase A/B/C or total. The register is calcu-
lated according to the following formula:
This register contains the apparent accumulated energy delivered into phase A/B/C or total. The register is the prod-
uct of the ENR_CC and X.ES registers.
