CCS0
This bit defines the characters colour. When the character has no window background
with it, colour 0 is selected if CCS0 = 0, otherwise colour 1 is selected. When the
character is inside a window and the CCS1 bit of the corresponding windows control
register is 0, the colour selection is the same as no window background, and if
CCS1 = 1, colour 2 is selected when CCS0 = 0, otherwise colour 3 is selected.
These 7 bits define 1 of 128 character symbols to be displayed in this position.
