This pin lets you adjust the level at which the cycle skipping process takes
place. Shorting this pin to ground, permanently disables the skip cycle
feature.
By connecting an optocoupler to this pin, the peak current setpoint is
adjusted accordingly to the output power demand.
This pin senses the primary current and routes it to the internal comparator
via an L.E.B.
