Chapter 4 - Color Liquid Crystal Display Controller; Table 4-9. Color Stn Intensities From Gray-Scale Modulation - Sharp LH79524 User Manual

LH79524/LH79525 User's Guide
Table 4-9 shows the intensity that can be obtained from each of the 16 possible 4-bit pal-
ette combinations. Only 15 of the combinations are useful because the values 0b0110 and
0b1000 produce the same result.
