From signal P (3-ph active energy), stepper motor driving signals MA and MB (see

to MOP and MON pins.
The numbers of pulses per kWh on MOP and MON outputs (CM) is related to the number of
pulses on LED pin (C, see par.
Configuration of MOP and MON driving signals with APL = 1, 2, 3
The mono-flop limits the length of the pulses according to the LVS bit value.
The decoder distributes the pulses to MA and MB alternatively, which means that each of
them has only a half of selected frequency.
When a no-load condition is detected ( BIL =1) MOP and MON are held low because
integration of power is suspended.
The LED pin provides 3-phase active energy pulses according to the table below:
