BITS
bits <2:0> are equivalent to the RGB components. SCREEN COL<2:0>:
National Option Table selection, maximum of 31 when used with EAST/WEST bit
forces the DISP FIELD bit in STATUS MMR to be toggled every Vsync (logic 1)
basic character set selection
enable twist character set (logic 1)
language control bits (C12, C13 and C14) that has twisted character set
twist character set selection
re-map column 8/9 to DRCS (or column 8/9/A/C/ if Extended DRCS is enabled),
TXT and CC modes (logic 1)
character code columns 8/9 (or column 8/9/A/C/ if Extended DRCS is enabled),
defined as double plane characters (special graphics characters) (logic 1)
characters, in CC mode only (logic 1)
enables character set selection in CC display mode (logic 1)
enable use of OSD LAN<2:0> to define language option for display, instead of
C12, C13 and C14
alternative C12, C13 and C14 bits for use with OSD menus
