These waveforms demonstrate how to establish the direction of energy flow as well as the
phase from which the energy is measured. The direction of energy indicated on pin DIR is
HIGH for POSITIVE energy flow and LOW for NEGATIVE energy flow, for the entire LOW
period of the FOUT1 pulse. The phase to which the direction indication on the DIR pin
refers can be ascertained by counting the number of falling edges on the DIR pin prior to
the falling edge of the FOUT1 pulse. The supervision of the DIR pin can be accomplished
with a
µController.
Although FOUT1 has a fixed frequency output, the table below shows the various
frequencies selectable for rated condition on FOUT2.
