COLOURS
A Colour Look-Up Table (CLUT) with 16 colour entries is
provided. The colours can be programmed from a palette
of 4096 (4 bits per R, G and B), as shown in Table 28. The
CLUT is defined by writing data to a RAM that resides in
the MOVX address space of the 80C51. When set, the
colours are global and apply to all display windows.

23.4.6
FOREGROUND COLOUR
CC: The foreground colour can be chosen from eight
colours on a character by character basis. Two sets of
eight colours are provided. A serial attribute switches
between the banks (see Table 33 Serial Mode 1, bit 7).
The colours are the CLUT entries 0 to 7 or 8 to 15.
TXT: The foreground colour is selected via a control
character (see Fig.33). The colour control characters takes
effect at the start of the next character (‘set after’) and
remain valid until the end of a row of a display window, or
until modified by a control character. Only eight foreground
colours are available.
The TEXT foreground control characters map to the CLUT
entries, as shown in Table 29.
