Abstract: In a digital communication system, a master device and a number of slave devices are coupled in communication with the master device over a shared data communication bus. A selection line for each one of the slave devices couples the master device with a respective slave device and is dedicated to selection by the master device of the respective slave device for communication over the shared data communication bus. Each of the slave devices is able to send an interrupt request to the master device over the respective selection line to be served by the master device initiating a communication over the shared data communication bus, each selection line thereby being a bidirectional communication line between the respective slave device and the master device.

Abstract: In a digital communication system, a master device and a number of slave devices are coupled in communication with the master device over a shared data communication bus. During an address assignment procedure, the master device assigns different respective dynamic addresses to the slave devices in order to address the slave devices for data communication; during the address assignment procedure, the slave devices are arranged in a daisy-chain configuration, wherein each slave device has a daisy-chain input and a daisy-chain output, the daisy-chain input of a slave device being coupled to the daisy-chain output of a previous slave device in the daisy chain configuration, the daisy-chain input of a first slave device being coupled to a daisy-chain enabling output of the master device; in particular, the master device is configured to assign the respective dynamic addresses to the slave devices based on their arrangement in the daisy-chain configuration.
