The present disclosure relates to a method comprising receiving edges conveyed by a serial bus and separated by multiples of a same duration, determining a measurement value of a ratio between a cycle time of a clock and the duration, and sending bits on the serial bus using the measurement value.

Apparatus and method for communication on a serial bus

The present disclosure relates to a method of communication via serial bus, comprising: the conveyance by the serial bus of a frame comprising at least two consecutive cycles of a dominant state followed by a recessive state, the recessive states and dominant states having durations comprised between 2 and 5 times the duration of a data bit conveyed by the serial bus, and preferably above 1.8 μs; and the detection by one or more circuits coupled to the serial bus of at least a part of the frame for triggering the passage from a sleep state to a wake state of the one or more circuits.

An embodiment method comprises receiving at least one frame comprising consecutive bits transported by a serial bus; estimating an arrival period of a last bit of the consecutive bits; and starting a sending of an acknowledgement of receipt before the end of the estimated arrival period.
