The Host Interface provides the means for the CPU/MPU to communicate with the display buffer
and internal registers.
The Memory Controller arbitrates between CPU accesses and display refresh accesses. It also
generates the necessary signals to control the SRAM frame buffer.
The Sequence Controller controls data flow from the Memory Controller through the Look-Up Table
and to the LCD Interface. It also generates memory addresses for display refresh accesses.
The Look-Up Table contains three 256 4 Look-Up Tables or palettes, one for each primary color.
In monochrome mode only the green Look-Up Table is used.
