Address pointers
The address of the first byte (in the SDRAM) of the first color which will be loaded from the
palette to the OSD CLUT is defined in bits Palettep[31:0]. If a new palette (CLUT
programmed in the SDRAM) must be loaded when the OSD displays a new OSD region, the
New Palette (NP) bit must be set.
