Hello,

The UB948 can be configured to output RGB888 or RGB666 with either JEIDA or VESA mapping schemes. Mapping scheme selection is controlled by the MODE_SEL0 pin or may be overridden in register 0x49.

Hi Ben:

Which one is ok? Configured to 0x61/0x41/0x60/0x40? Thanks.

Hi Arvin,

If you want 24-bit Dual FPD-Link JEIDA format (LSB on D3/D7) as shown below, writing 0x40 to register 0x49 will do this.
