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, 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, the 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; usually 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.
