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 conditions on FOUT2.
