3.4.4 MIPI DSI Display Interface

The MIPI Display Serial Interface (DSI) Host Controller is a digital core that implements all protocol functions defined in the MIPI DSI Specification. The DSI host provides an interface between the LCD Controller (LCDC) and the MIPI D-PHY, allowing communication with a DSI-compliant display.

The DSI sends data to a DSI-compliant display. A D-PHY configured as a host (TX) acts as the physical layer.

On the SAMA7D65-Curiosity Kit, an external MIPI display can be connected to the J16 34-pin FPC connector.
