Description

Accessory mode

Debug accessory mode. It is defined by the presence of pull-up resistors 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, 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; 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 VBUS and supports data.
