Four-color Display Mode
The HD66760 has the four-color display mode consisting of two-bit-per-pixel data. Since the byte-wise
processing of four-pixel display data is enabled, the processing performance is four times that of the normal
256-color display. When the internal grayscale palette is used, four colors of the possible 4,096 colors can be
displayed at the same time. The two-bit display data in the GRAM written from the microcomputer is
assigned to the lower two bits of R and G; one of these bits, always 0, synthesizes the three-bit data.
Therefore, this display mode uses 000, 001, 010, 011 in grayscale palettes R and G.
