Pixels with lower X coordinates are located from the left. These pixel data are represented by different digital data
depending on the graphic format setting. For example, one graphic pixel is represented by 16-bit digital data in 16
BPP mode. If these pixels are processed in the Mixer, the word format to represent these pixels is different
depending on the endian format.
In the big endian mode, the pixel with lower X coordinate is positioned to the MSB parts in the 64-bit register of
Mixer. However, in the little endian mode, the pixel with lower X coordinate is positioned to the LSB parts in the
64-bit register.
9.3.5 BACKGROUND LAYER
If there is no video or graphic, background color is seen in the display region. Use YCbCr[888] format to set the
background color in the register.
