Zusammenfassung:A circuit includes a set of LED driver devices and a controller including a set of nodes coupled to a first slave address pin and a second slave address pin in each LED driver devices in the set of LED driver devices. Each LED driver device includes: a finite state machine (FSM) configured to generate LED drive PWM-modulated signal patterns; an oscillator configured to generate a clock signal for the FSM; a first signal path activatable between the first slave address pin and the FSM; and a second signal path activatable between the FSM and the second slave address pin.
