REGISTER 3-12:
These four registers represent the total apparent energy accumulated so far. Energy
from each LINE_CYC line cycles is:
EQUATION 3-2:
Note that during calibration, this value, ENERGY_VA_Z, and ENERGY_VA_L_RAW
will all have the same value.
This register is updated every LINE_CYC line cycles (updating ends after first update
if calibration is enabled).
