Abstract:
1. An integrated circuit comprising: transmitter circuitry for transmitting data over a serial communications link; receiver circuitry for receiving data over the serial communications link; control circuitry for controlling the transmitter circuitry and receiver circuitry, wherein the transmitter circuitry, receiver circuitry, are configured to transmit regular data through a regular data port and are configured to transmit priority data through a priority port, wherein when there is priority data to be sent through the priority port the transmission of regular data through the regular data port is interrupted and the priority data is nested within the regular data; and a data encapsulation circuit that encapsulates the regular data and priority data between two-byte start-of-packet codes and two-byte end-of-packet codes, wherein when the priority data is nested within the regular data, the start-of-packet and end-of-packet codes associated with the priority data are nested within the regular data.
