Description

Accessory modes

Audio adapter accessory mode. It is defined by the presence of Ra/Ra on the CC1/CC2 pins.

Debug accessory mode. It is defined by the presence of Rd/Rd on CC1/CC2 pins in source

power role or Rp/Rp on CC1/CC2 pins in sink power role.

DFP

Downstream facing port, specifically associated with the flow of data in a USB connection.

Typically, the ports on a HOST or the ports on a hub to which devices are connected. In its

initial state, DFP sources VBUS and VCONN, and supports data.

DRP

Dual-role port. A port that can operate as either a source or a sink. The port role may be

changed dynamically.

Sink

Port asserting Rd on the CC pins and consuming power from the VBUS; most commonly a

device.

Source

Port asserting Rp on the CC pins and providing power over the VBUS; most commonly a host

or hub DFP.

UFP

Upstream facing port, specifically associated with the flow of data in a USB connection. The

port on a device or a hub that connects to a host or the DFP of a hub. In its initial state, the

UFP sinks the VBUS and supports data.
