4.5 Memory Organization for 16 Bpp (65536 Colors/64 Gray Shades)
Figure 4-5: Pixel Storage for 16 Bpp in Two Bytes of Display Buffer
At a color depth of 16 bpp the S1D13708 is capable of displaying 64K (65536) colors. The
64K color pixel is divided into three parts: five bits for red, six bits for green, and five bits
for blue. In this mode the LUT is bypassed and output goes directly into the Frame Rate
Modulator.
Should monochrome mode be chosen at this color depth, the output sends the six bits of the
green component to the modulator for a total of 64 possible gray shades. Note that since 8
bpp also provides 64 gray shades, it is recommended to use 8 bpp for monochrome mode
in order to reduce the amount of display memory used.
