Abstract: Systems, methods, and apparatus are described that enable a serial bus to be operated in one or more modes that employ additional wires for communicating data. A method for transmitting data over a serial bus includes receiving from a first line of the serial bus a clock signal used for timing transmission of data on a second line of the serial bus, activating a driver after the first line has transitioned from a first signaling state to a second signaling state while the data is being transmitted on the second line, driving the first line to the first signaling state to transmit a first bit of data when the first bit of data has a first value, and refraining from driving the first line to the first signaling state to transmit a first bit of data when the first bit of data has a second value.

Abstract: Systems, methods, and apparatus for communicating datagrams over a serial communication link are provided. A transmitting device generates an address field in a datagram, sets a value of at least one bit in the address field to indicate a number of bytes of data associated with a data frame of the datagram, generates the data frame in the datagram, the data frame including the number of bytes of data, and sends the datagram to a receiving device. A receiving device receives a datagram from a transmitting device, decodes an address field of the datagram to detect a number of bytes of data included in a data frame of the datagram based on a value of at least one bit in the address field, and decodes the data frame to recover the detected number of bytes of data.
