Abstract
Advanced TDM daisy-chain configurations utilize data transmission over a frame sync signal path with feedback to allow for communication between the master device and slave devices and/or between individual slave devices while maintaining a simple TDM communication interface. In certain daisy-chain configurations, the feedback path returns to the frame sync signal path between the master device and the first slave device, which allows for transmission of data from the last slave device to the master device and/or to the first slave device. In other daisy-chain configurations, the feedback path returns to the frame sync signal path between the first slave device and the second slave device, which allows for transmission of data from the last slave device to the first slave device (which may transfer data to the master device, e.g., over separate command and/or data lines) and/or to the first slave device.
