Abstract: SoundWire-based embedded debugging in an electronic system is provided. In this regard, in one aspect, a SoundWire slave circuit receives a SoundWire data input signal over a SoundWire bus including two physical wires. The SoundWire data input signal includes a plurality of debug configuration bits in assigned SoundWire bitslots. The SoundWire slave circuit generates a plurality debug input bits required for debugging the SoundWire slave circuit based on the debug configuration bits received in the assigned SoundWire bitslots. In another aspect, the SoundWire slave circuit returns a SoundWire data output signal, which includes a debug output bit in an assigned SoundWire bitslot, over the SoundWire bus. By receiving debugging configurations and returning debugging results over the SoundWire bus, it is possible to debug the SoundWire slave circuit with a reduced number of physical pins, thus helping to reduce the overall pin count and footprint of the electronic device.
