Another app note from Fairchild Semiconductors on USB Type C to USB legacy design considerations. Link here (PDF)

When designing hardware systems with type C connectors, a designer also has to consider all legacy, standard, and nonstandard specifications that exist in the USB connector eco system. With the introduction of the Type C connector and the Configuration channel (CC Pin) new challenges occur trying to ensure overall system robustness. This note addresses some of the concerns with the CC pin in a robust system environment.
