3.4.4 LVDS Display Interface
The Low Voltage Differential Signaling Controller (LVDSC) manages data format conversion from the LCD Controller internal DPI bus to OpenLDI LVDS output signals.
LVDSC functions include bit mapping, balanced mode management and serializer.
On the SAM9X75 Curiosity Pro, the display is connected to 30-pin FPC connector J68.
