A circuit includes a high priority circuit and a non-high priority circuit. The high priority circuit is operative to communicate high priority information to a single path of a differential serial communication link. The non-high priority circuit communicates non-high priority information to the single path. The high priority information is communicated prior to the non-high priority information. In one example, the circuit includes a flow control distributor operatively coupled to the high priority circuit and the non-high priority circuit. The flow control distributor distributes a total number of flow control credits into high priority credits and non-high priority credits. The flow control distributor controls communication of the high priority information based on the high priority credits. The flow control distributor controls communication of the non-high priority information based on the non-high priority credits.
