7.3.6 Plug Polarity Detection

Reversible Type-C plug orientation is reported by the POL pin when a Sink is connected, however when no Sink is attached, POL remains de-asserted irrespective of cable plug orientation. Table 2 describes the POL state based on which device CC pin detects VRd from an attached Sink pull-down. In a typical USB 3.x DFP port, this pin controls a superspeed data MUX for proper data connectivity irrespective of plug orientation. See Figure 20.
