(CLUT)
A Colour Look-up Table with 16 colours is provided. The colours are programmable from a palette of 4096 (4 bits per R,
G and B). The CLUT is defined by writing data to the RAM as described in Section 18.6.

LANKING POLARITY
The polarity of the Fast Blanking signal (FBL) can be inverted. When inverted the values of the RGB outputs during line
fly-back periods are also inverted. The polarity is set using the FBPOL bit in the RGB Brightness Register (see
Section 18.9.8).

ONTROL
A brightness control is provided that allows the RGB output voltages to be modified. The brightness is set using the
BRI0 to BRI3 bits in the RGB Brightness Register (see Section 18.9.8).
