USB Type-C Alternate Mode Reference Design

The USB Type-C Alternate Mode Reference Design is a virtual reference design where the schematics, software, and videos are available to aid developers in creating an Alternate Mode USB Type-C Solution. This reference design features 2 Power Delivery (PD) controllers and one Alternate Mode USB controller. It is able to take in display port data and convert this to USB Type-C while also either receiving power or sending power via the 2 PD controllers. This design takes advantage of the EFM8 BB3 PD controller and the EFM8 UB1 USB controller to create a complete USB Type-C solution.
