Four-grayscale Display Function
The HD66750/1 supports the four-grayscale monochrome display function. The four-grayscale
monochrome display is used for the display data of the two-bit pixel set sent to the CGRAM. There are four
grayscale levels: always unlit, weak middle level, strong middle level, and always lit. In the weak
middle-level grayscale display, the GS bit can select the 1/3 or 1/2 level.
The frame rate control (FRC) method is used for grayscale control.
