Technical Field

Background

The USB Type-C standard introduces dual role capability, with both ends of each USB Type-C cable being identical, so two devices must communicate with each other to confirm whether the host is a peripheral or a host. The role communication is performed after the cable is connected, and the host port for data communication is called a downstream port (DFP), i.e., an upstream port (UFP). In terms of power supply, the power supply end is called a source end, and the power consumption end is called a suction end. Devices may have Dual Role (DRD) capability on data or Dual Role (DRP) capability on power. And the CC line plays a role in defining the role of power supply during the connection of two devices.

However, some low-end embedded platforms or earlier-pushed processors do not have a native Type-C interface, which is generally required to support the Type-C interface through a bridge conversion scheme, which is relatively costly and does not support the PD protocol of power delivery.
