4 It monitors and controls System Policy between various Providers and Consumers connected via USB. Device Policy Manager (one per Provider or Consumer) provides mechanisms to monitor and control the USB-PD within a particular Provider or Consumer. It enables local policies to be enforced across the system by communication with the System Policy Manager. Policy Engine(one per Source or Sink Port) interacts directly with the Device Policy Manager in order to determine the present local policy to be Protocol Layerforms the messages used to communicate information between a pair of ports. It receives inputs from the Policy Engine indicating which messages to send and indicates the responses back to the Policy EnginePoliciesProtocol LayerIt is responsible for sending and receiving messages across either the VBUSor CC wire. It consists of a transceiver that superimposes a signal (BFSK on VBUSor BMC on CC) on the wire.
