Low-Power, Active Energy, Polyphase AFE
This register contains the value by which the raw power value in each phase is multiplied before being presented to
the virtual power registers. The table below lists the raw power registers and the corresponding virtual registers.
PWR_CC establishes the amount of power represented by one PWR_LSB of the power registers. To avoid significant
conversion loss, PWR_LSB should be chosen such that PWR_CC is > 1000. Calculate the value of PWR_CC accord-
ing to the following formula:
