Table 13-8. Color Stn Intensities From Gray-Scale Modulation - Sharp Blue Treak LH75400 User Manual

LH75400/01/10/11 (Preliminary) User's Guide
Table 13-8 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 two middle values
produce the same result.
