7.3.5 Frame Buffer Memory Size
Several screens may be available for video display depending on screen size, pixel depth,
and amount of memory dedicated to video images. The screen size can be up to 1280 x 1024
pixels, the pixel depth can be 4 bpp, 8 bpp, 16 bpp, 24 bpp packed, or 32 bpp (24 bpp
unpacked).
7.3.6 Pulse Width Modulated Brightness
The circuitry provides a pulse width modulated brightness control output, Bright, that can be
used in conjunction with an external resistor and capacitor to provide a DC voltage level for
