A system including a first port configured to simultaneously couple with a first device and a second device; and a management circuit configured to route a data signal received from a first controller to the first device in response to receiving a first-device direction from the first controller and route the data signal received from the first controller to the second device in response to receiving a second-device direction from the first controller unless an override condition for the management circuit is satisfied.

Method for managing the operation of a system on chip, and corresponding system on chip

The system on a chip includes at least a first digital domain configured to be reinitialized by a first reinitialization signal, a second digital domain and an interface circuit. The interface circuit includes a starting register in the first digital domain, a destination register in the second digital domain and a synchronization circuit in the first digital domain. The interface circuit is configured to transfer data from the starting register to the destination register upon command of a control signal transmitted by the synchronization circuit. The starting register and the synchronization circuit are configured to not be reinitialized by the first reinitialization signal.
