If APL=2 then LED provides high frequency
pulses proportional to Active Energy with 50%
duty cycle.
If APL=3 then LED provides pulses proportional
to Active Energy (internal signal AW). The
number of pulses per kWh can be selected
according to the value of KMOT configuration bit.
No-load indicator:
when low, a no-load condition is detected
Tamper indicator:
when low tamper condition is detected
Negative active power indicator:
when low a negative active power condition is
detected
Must be high to activate SCLNLC, SDATAD and
SYN indications
(APL register=2 or 3)
Stand-alone mode

If APL=0 then Watchdog signal.
If APL=1 then ΔΣ signal of current channel
If APL=0 then ZCR
If APL=1 then ΔΣ signal of voltage channel
If APL=0 then LED can provide Active,
Reactive or Apparent Energy according to
value of KMOT configuration bit.
If APL=1 then LED is connected to the MUX
signal generated from the tamper detection
circuit.
When LED=low then the primary current
channel is selected, if LED=high the
secondary current channel is selected.
Used for SPI interface (see SPI interface
section for details)
