Here is the Red grayscale LUT, in the order as would be seen in the EP93xx User’s Guide table “Grayscale
Look-Up Table (GrySclLUT)”. Note that the upper-order bits D[18:16] are set in all registers, but only the
settings in base+0x0 through base+0x1C are used by the grayscale generator to determine if 3- or 4-count
entries are used.
