bits 4-2 Number of Bits-Per-Pixel Select Bits [2:0]
These bits select the number of bits-per-pixel (bpp) for the displayed data.
Note
15 and 16-bpp modes bypass the LUT and are supported as 12-bpp on passive panels and 15/16-
bpp on TFT panels. These modes are not supported on CRT. See Figure 10-2: “15/16 Bit-Per-
Pixel Format Memory Organization,” on page 117 for a description of passive panel support.
