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 optionally 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.

Source

Port asserting Rp on the CC pins and providing power over the VBUS.

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.
