Abstract: Systems, methods, and apparatus for data communication are provided. A method performed by a bus master includes terminating transmission of a first datagram by signaling a first bus park cycle on a serial bus, causing a driver to enter a high-impedance state, opening an interrupt window by providing a first edge in a clock signal transmitted on a second line of the serial bus, closing the interrupt window by providing a second edge in the clock signal, signaling a second bus park cycle on the serial bus, initiating an arbitration process when an interrupt was received on the first line of the serial bus while the interrupt window was open, and initiating a transmission of a second datagram when an interrupt was not received on the first line of the serial bus while the interrupt window was open.
