Manipulation of RGB data

It is possible to modify the encapsulation of the RGB data in a number of ways:

â swap the location of the RED and BLUE data

â reverse the bit order of the individual color channel data

â reverse the order of the data bytes themselves

Dithering

An optional dithering function can be enabled for each RGB output mode to reduce the

appearance of contours produced by RGB data truncation. This is enabled through the

DitherControl register.
