Abstract
Communication circuitry, comprising: N communication nodes being clock-candidate nodes, where N≥2; N communication units for communication using respective communication protocols, and connected or connectable to receive respective clock signals for communication under their respective communication protocols via respective said clock-candidate nodes; and a control unit configured, in a decision operation, to monitor the clock-candidate nodes and decide which of the communication protocols is in use dependent on at which of the clock-candidate nodes a received clock signal is detected, wherein at least one said communication unit is connected or connectable to receive and/or transmit data under its respective communication protocol via at least one said clock-candidate node other than the clock-candidate node via which that communication unit is to receive its respective clock signal.
