Figure-3 Energy Register Operation Diagram
For all-phase-sum total of active, reactive and (arithmetic sum)
apparent energy, the associated power is obtained by summing the
power of the three phases. The accumulation method of all-phase-sum
energy is determined by the EnPC/EnPB/EnPA/ABSEnP/ABSEnQ bits
(b0~b4, MMode0).
Note that the direction of all-phase-sum power and single-phase
power might be different.
