SA9602M
The pulse rate of the LED output is fixed at 1000 pulses/kWh when MD = 1. This
high rate of pulses is preferred for such tasks as calibration, verification and
monitoring of consumption rate. The LED waveform is as shown below:

Direction, Indication and Selection
The SA9602M provides information on the energy flow direction on pin DIRO.
A logic 0 on pin DIRO indicates reverse energy flow. Reverse energy flow is defined
as the condition where the voltage sense input and current sense input are out of
phase.
Positive energy flow, when voltage sense and current sense input are in phase, is
indicated on pin DIRO a logic 1.
The DIRO pin may be used to drive a LED in order to indicate reverse energy.
