46.6.3 Display Software Configuration
46.6.3.1 System Bus Access Attributes
These attributes are defined to improve bandwidth of the pixel stream.
 LOCKDIS field: when set to one the AHB lock signal is not asserted when the PSTRIDE value is different from
zero (rotation in progress).
 ROTDIS field: when set to one the Pixel Striding optimization is disabled.
 DLBO field: when set to one only defined burst lengths are performed when the DMA channel retrieves the data
from the memory.
 BLEN field: defines the maximum burst length of the DMA channel.
 SIF field: defines the targeted DMA interface.
46.6.3.2 Color Attributes
 CLUTMODE field: selects the color lookup table mode
 RGBMODE field: selects the RGB mode.
 YUVMODE field: selects the Luminance Chrominance mode.
