2.13.7.5.1. CLUT Access for ROM Characters/1-bit
For each pixel of a character a 1-bit background/fore-
ground information is available. 1 out of 8 sub CLUTs
can be selected by character display word (CDW; see
also Section 2.13.4.). 1 out of 8 color vectors can be
selected as a foreground and background color vector
by the character display word (CDW; see also
Section 2.13.4. on page 70). Please notice Table 2–68
on page 90.

2.13.7.5.2. CLUT Access for 2-Bit DRCS Characters
2-bit DRCS characters are stored in the RAM. Within a
2-bit DRCS character a 2-bit color vector information is
available for each pixel. By this 2-bit information 1 out
of 4 color vectors is selected from a subCLUT.
1 out of 8 subCLUTs is selected by character display
word (CDW; see also Section 2.13.4. on page 70).
Please notice Table 2–68 on page 90.
