7.3.1.1 Downstream Facing Port (DFP) - Source

The TUSB321 device can be configured as a DFP only by pulling the PORT pin high through a resistance to VDD. In DFP mode, the TUSB321 device constantly presents Rps on both CC. In DFP mode, the TUSB321 device advertises USB Type-C current based on the state of the CURRENT_MODE pin.

When configured as a DFP, the TUSB321 can operate with older USB Type-C 1.0 devices except for a USB Type-C 1.0 DRP device. The TUSB321 can not operate with a USB Type-C 1.0 DRP device. This limitation is a result of backwards compatibility problem between USB Type-C 1.1 DFP and a USB Type-C 1.0 DRP.
