This recommended palette assumes that you are using only bank 0 of the three color components. By programming in the above fashion the following colors will result:

15 bpp Color

Since the Look-Up Table is bypassed in this mode, the LUT programming is unimportant. The colors on the display are derived from only the top 4 bits of each color combination. Resulting in a maximum of 212=4096 colors.

16 bpp Color

Since the Look-Up Table is bypassed in this mode, the LUT programming is unimportant. The colors on the display are derived from only the top 4 bits of each color combination. Resulting in a maximum of 212=4096 colors.

Gray Shade Modes

In gray shade mode, the S1D13504 treats the Green LUT as a 16 position, 4 bit wide monochrome LUT. Depending on the selected pixel size, this LUT will provide from 1 to 4 banks.

1 bpp Gray Shade

The S1D13504 has no true Black-and-White mode. 1 bpp Gray consists of a single bank of two entries. For Black-and-White mode, the LUT entry must be programmed as such:
