This signed register provides the raw real energy accumulated over the most recent DSP cycle. For each ADC sam-
ple period, the real instantaneous power calculated from the instantaneous voltage and current is accumulated. At
the end of each DSP cycle, the result of the accumulation over the DSP cycle is copied to this register and is accu-
mulated in X.EAPOS or X.EANEG, depending on the sign of the accumulated energy.
LSB of the energy registers is V
This signed register provides the raw reactive energy accumulated over the most recent DSP cycle. For each ADC
sample period, the reactive instantaneous power calculated from the instantaneous voltage and current is accumu-
lated. At the end of each DSP cycle, the result of the accumulation over the DSP cycle is copied to this register and
is accumulated in X.ERPOS or X.ERNEG, depending on the sign of the accumulated energy.
