BIT SYMBOL
DESCRIPTION

CDTW
Character dot width control
.The state of this bit determines the dot width of the character. When
the CDTW bit is set to:
Logic 1, the character width is 6 dots.
Logic 0, the character width is 8 dots.
Character dot height control
. The state of this bit determines the dot height of the character. When
the CDTH bit is set to:
Logic 1, the character height is 13 dots.
Logic 0, the character height is 9 dots.
Colour control bits.
In every VSYNCN cycle one screen can select any 4 colours from 7 and in addition a blank or black
screen. Combinations of CC1X, CC2X and CC3X control the character outputs VOW1, VOW2 and
VOW3 as shown in Table 24.
