OG exemplary drawing
 
1. A system on chip comprising:
at least one master device;
at least one slave device;
a connection interface connected to the at least one master device and the at least one slave device, the connection interface configured to:
route signals between the at least one master device and the at least one slave device, and
operate according to configuration parameters; and
a configuration bus connected to the connection interface,
wherein the configuration bus, the at least one master device and the at least one slave device are independently connected to the connection interface,
wherein the configuration bus is configured to deliver new configuration parameters to the connection interface so as to adapt operation of the connection interface,
wherein the connection interface comprises a selection circuit configured to select the configuration parameters between the new configuration parameters and default configuration parameters, and
wherein the selection circuit is configured to select a new configuration parameter based on a value of a guard bit guarantying that the new configuration parameter is valid.
