The Source supplies pull-up resistors (Rp) on CC1 and CC2 and monitors both to detect a Sink. The presence of an Rd pull-down resistor on either pin indicates that a Sink is being attached. The value of Rp indicates the initial USB Type-C Current level supported by the host. The Sou...

The Rp resistor pulls up the CC1 and CC2 pins in DFP, but Rd pulls them down in UFP. The source detects a logic high level at the CC1 and CC2 pins if the cable is not attached. By connecting the USB Type-C cable to the 5V power supply, a current route from the power supply...
These pull-ups seem to be somewhat separate from normal pinmuxing, so I'm not sure where this should be fixed. Possibly in some generic init code for this MCU, as the reference manual says:After exiting reset, the USB Type-C “dead battery” behavior is enabled, which may have a pull...
Cables with an eMark IC will have an internal 1k pull-down resistor Ra on the VCONN pin, so Ra has a lower value than Rd which is typically 5.1k. After inserting this type of cable, the Source will see both CC1 and CC2 pin voltages dropping. The voltage levels will tell the host ...
