Feature Description (continued)

Figure 10. USB-PD Physical Layer and Simplified Plug and Orientation Detection Circuitry

USB-PD messages are transmitted in a USB Type-C system using a BMC signaling. The BMC signal is output

on the same pin (C_CC1 or C_CC2) that is DC biased because of the DFP (or UFP) cable attach mechanism

discussed in the Cable Plug and Orientation Detection section.
