Abstract: Some embodiments include a method of communication between a master device and N slave devices on a synchronous data bus. The method includes selecting a slave device from among the N slave devices using a selection channel, where the master device and the N slave devices are coupled in series through the selection channel. The method also includes transmitting data between the master device and the selected slave device using a transmission channel, where the master device and the N slave devices are coupled in parallel through the transmission channel.
