1. A device comprising:
a data terminal configured to be connected to a serial data line,
a clock terminal configured to be connected to a serial clock line for receiving a clock signal, and
a digital circuitry coupled to the data terminal and to the clock terminal,
wherein the digital circuitry is configured to operate based on a time base signal provided via a further clock terminal to the device or based on an internal clock signal generated by an internal oscillator of the device, wherein the device is configured to adjust the internal oscillator based on the clock signal and wherein the digital circuitry is configured to provide a data signal at the data terminal based on a detection of flicker light detected by the device.
