The Signal ON switches the illumination in PWM-Mode.
The Duty Cycle of Signal PWC controls LED current in PWM-Mode.
The FAIL Signal signals Error States in PWM Mode, Bulb Mode and Analog Mode.
For a detailed description of the logical behavior of this signals, see section 6.5.3.3.
The two Inputs ON and PWC are opto-coupled inputs with a common GND line COMMON.
The Output Signal FAIL is also opto-coupled with an open collector circuit to COMMON.
