On-Screen Display (OSD)
OSD Registers
NOTE:
The width of bottom side shadowing is counted in numbers of columns
and is aligned with the character width (12 dots or 16 dots) of the
following row. Therefore it is possible to have misalignment of this
shadowing while different character formats are used by the last row
inside the window and first row outside the window. The window
shadowing width of row 14 is determined by number of columns of
window times 12 dots.
Row 15, Column 20:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
RSPACE
MSB
LSB
RSPACE — Row Spacing
These bits define the spacing between the display rows, in units of
horizontal scan lines. Due to the non-uniform expansion of the BRM
algorithm used for character height control, this register is normally
used for maintaining a constant OSD menu height for different display
modes, instead of adjusting the character heights. The default value
is 0, i.e. no extra lines inserted between.
Row 15, Column 21:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
PGE
PGR PGG PGB
PGE — Screen Video Pattern Enable
Set this bit to enable the free-running full-screen video pattern. Reset
clears this bit.
1 = Screen video pattern enabled
0 = Screen video pattern disabled
PGR, PGG, PGB — Screen Video Pattern Color
These bits define the color of the free-running full-screen video
pattern.
