Function
7
1
1 = 10 pixel/character
0 = 8 pixel/character
6
0
1 = double dot size in vertical direction
(OSD layer only)
0 = normal dot size in vertical direction
5
0
1 = double dot size in horizontal direction
(OSD layer only)
0 = normal dot size in horizontal direction
4
0
1 = black colors replaced by transparent & shadow
(OSD layer only)
0 = black colors displayed black
3 to 0
F H
4-bit value defining delay of horizontal start for both layers (in pixel)
delay = mod16 (character_width – 2 – value)
(leftmost position should not be used!)

Reset
Function
2
0
1 = boxing enable
0 = boxing disable
1

Function
7 to 0
–
8 least significant bits of 21 bit address pointer
12 LSBs of 21 bit address pointer are running with autoincrement
read value is only specified when pointer is not incrementing

–
8 medium bits of 21 bit address pointer
12 LSBs of 21 bit address pointer are running with autoincrement
read value is only specified when pointer is not incrementing
writing this register clears all lower bits of related pointer
