Abstract: A data communication system has a number of communicatively coupled devices, including at least one slave-only device. Techniques for use in the data communication system include techniques for synchronization and re-synchronization of frame and bit clocks, techniques for assigning device address, techniques for dynamically controlling transmit power based on the number of devices, and techniques for serialized signal processing.

Abstract: A method of operating a microphone system includes the steps of monitoring an I/O terminal to detect whether a signal on that terminal achieves a pre-defined logic level during a monitoring period. The I/O terminal and a second I/O terminal are configured to one of a hardware mode or a communications-bus mode depending on whether the pre-defined logic level is detected. A microphone system includes two I/O terminals and an automatic detection and mode switching circuit, as well as a communications bus interface circuit and a hardware control circuit. The mode automatic detection and mode switching circuit couples the two I/O terminals to either the communications bus interface circuit or the hardware control circuit in response to the logic level detected on one of the I/O terminals during a monitoring period.

Abstract: A simplified bus arrangement using only three signal lines allows TDM data to be conveyed to or from a number of slave-only devices without the use of separate command line(s) and without any of the slave-only devices having to operate as a bus master or even support a master operating mode.

Abstract translation: 仅使用三条信号线的简化总线布置允许将TDM数据传送到或从多个从属设备传送，而不使用单独的命令行，并且没有任何从属设备必须作为总线操作 掌握甚至支持主操作模式。
