Configuration ChannelProviding the flexibility of Type C
Functionally the Configuration Channel (CC) is used to serve the following purposes:
Detect connect of USB ports,
Resolve cable orientation and twist connections to establish USB data bus routing
Establish DFP (sink) and UFP (source) roles between two
connected ports
Discover and configure power: USB Type- C current modes or USB Power Delivery
Discovery and configuration of optional Alternate and Accessory modes
Typical CC flow for DFP to UFP configuration:
Detect valid connection Establish USB power method Configure as a DFP or UFP

Typical Behavior upon Attachment
The CC2 / CC line shows the voltages on the configuration channel between the sink
and a source that applies VCONN to the cable.
t1: the cable is attached.
t2: the source confirms a valid sink is attached,
then applies 5V to VBUS and VCONN.
t3: USB Type C 3A advertisement begins &
USB PD messaging begins on CC line
t4: VBUS voltage is increased to negotiated level.
