ATA TO OUTPUT MAPPING
Each colour of each pixel is handled separately. In double
pixelmodethereare6 bytes(red,greenandblueofpixel 0
and pixel 1 from which pixel 0 arrives first). In single pixel
mode there are 3 bytes (red, green and blue of pixel 0).
Each of the six output ports (see Fig.27) can be connected
to each colour and can be inverted, swapped and aligned
to the MSB (sensible to drive 6-bit panels).
Registers OI_B0R, OI_B0G, OI_B0B, OI_B1R, OI_B1G
and OI_B1B have to be programmed according to
Table 55.

If this bit is set to logic 1, then the lower 6 bits are aligned to MSB.
If this bit is set to logic 1, then swap [7:0] to [0:7]; LSB becomes MSB.
If this bit is set to logic 1, then bit wise inversion of the colour component.
Output port Px gets data byte with 6 bytes in double pixel mode or 3 bytes in
single pixel mode (for x = A to F):
