NEGATIVE POWER INFORMATION
The ADE7752B detects when total power, calculated as the sum
of the three phases, is negative. This mechanism can detect an
incorrect connection of the meter or generation of negative
active energy. The REVP pin output goes active high when
negative power is detected on the sum of the three phase inputs.
If positive active power is detected on the sum of three phases,
then REVP pin output is low.
The REVP pin output changes state at the same time as a pulse
is issued on CF. If the sum of the phases measure negative
power, then the REVP pin output stays high until the sum of the
phases measures positive power.
