2 Since the LCDC supports maximum 24-bit data width TFT panels, no LCD panel data width configuration is re-
quired.
When using a 12-bit data width TFT panel, connect it to the R7–R4, G7–G4, and B7–B4 pins.
When using a 16-bit data width TFT panel, connect it to the R7–R3, G7–G2, and B7–B3 pins.
When using a 18-bit data width TFT panel, connect it to the R7–R2, G7–G2, and B7–B2 pins.
