CLUT (Colour Look Up Table)
A CLUT (Colour Look Up Table) with 16 colour entries is provided. The colours are programmable out of a
palette of 4096 (4 bits per R, G and B). The CLUT is defined by writing data to a RAM that resides in the MOVX
address space of the 80C51
Foreground Colour
CC:- The foreground colour can be chosen from 8 colours on a character by character basis. Two sets of 8 col-
ours are provided. A serial attribute switches between the banks (see Table 21 Serial Mode 1, bit 7). The col-
ours are the CLUT entries 0 to 7 or 8 to 15.
TXT:- The foreground colour is selected via a control character (see Figure 31). The colour control characters
