PRODUCTION DATA.
Figure 10 shows the USB PD physical layer block surrounded by a simplified version of the analog plug and orientation detection block.
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.
