PRODUCTION DATA
Figure 8-3 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 (CC1 or CC2) that is DC biased due to the Rp (or Rd) cable attach mechanism.
