When an error occurs, resetting the IC can have a significant performance impact. An IC including nodes interconnected in a mesh network may employ a transmit control circuit coupled to a transmit node and a receive control circuit coupled to a receive node to reinitialize interface circuits on both ends of a node-to-node interface in response to a detected error in either a transmit node or a receive node.
