Abstract: A processing system comprising a first sub-circuit configured to be powered by a first supply voltage and a second sub-circuit configured to be powered by a second supply voltage. The first sub-circuit comprises a general-purpose input/output register. The second sub-circuit comprises: a storage circuit configured to selectively store configuration data from the general-purpose input/output register; an input/output interface, at least one peripheral and a selection circuits to exchange signals of the peripherals, and the stored configuration data with the input/output interface. A power management circuit is configured to manage a normal operating mode, and a low-power mode during which the configuration data are maintained stored and the first sub-circuit is switched off. The power management circuit activates the low-power mode in response to receiving a commands, and resumes the normal operating mode in response to a wake-up events.

Abstract: 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.
