Abstract
A communication system comprising: a digital serial bus, and a master device and at least one slave device connected to the bus. The master and the slave(s) are adapted to communicate according to a predefined communication protocol. The master is adapted for transmitting a continuous bitstream in the form of a plurality of frames, such that each frame comprises one or more words. Each word has a constant time duration, with the first word of each frame being a unique word transmitted by the master for indicating the start of a frame. One or more bits each word is transmitted by the master as a dominant bit; a non-dominant bit, for allowing the at least one slave to overwrite. The at least one slave is adapted for overwriting in the continuous bitstream some non-dominant bits to transmit data in a quasi-synchronous manner.
