Abstract: Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A method performed at a first device coupled to a serial bus includes receiving first coexistence information directed to a second device, selecting a communication link to carry the first coexistence information to the second device, generating a first datagram that includes the first coexistence information, transmitting the first datagram to the second device over a point-to-point link in a first mode of operation, and transmitting the first datagram to the second device over a multi-drop serial bus in a second mode of operation. The first datagram may be configured according to a protocol associated with the communication link selected to carry the first coexistence information.

Abstract: Transmission of data over a serial link based on a unidirectional clock signal is provided. A unidirectional clock signal is generated based on a first clock of a master device. The unidirectional clock signal is sent to a slave device that is connected to the serial link. The master device transmits data to the slave device over the serial link based on the first clock. The slave device receives the unidirectional clock signal from a master device. The slave device transmits data over the serial link to the master device based on the unidirectional clock signal.

Abstract: Serial communication using a packetization protocol engineered for efficient transmission is provided. Data link layer (DLL) control packets can be generated for transmission of control messages. Each DLL control message packet can have a DLL control packet length, and the DLL control packet length can be a fixed length. Physical layer (PHY) control packets can be generated. Each PHY control packet can include one of the DLL control packets and a control token. The length of each PHY control packet can be the sum of the DLL control packet length and a control token length of the control token. The PHY control packets can be encapsulated in frames. Each of the frames can include a synchronization symbol having a symbol length. The length of each frame can be the sum of the symbol length and an encapsulation length, which can be twice the length of the PHY control packet.
