Preliminary specification
Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA55xx
19.9.1
S
CREEN COLOUR DISPLAY AREA
This area is covered by the screen colour. The screen
colour display area starts with a fixed offset of 8
μ
s from
the leading edge of the horizontal sync pulse in the
horizontal direction. A vertical offset is not necessary.
Table 26
Screen colour display area
19.9.2
T
EXT DISPLAY AREA
The text area can be defined to start with an offset in both
the horizontal and vertical direction.
Table 27
Text display area
The horizontal offset is set in the MMR Text Area Start.
The offset is done in full width characters using TAS<5:0>
and quarter characters using HOP<1:0> for fine setting.
The values 00H to 08H for TAS<5:0> will result in a
corrupted display.
The value 09H should also be avoided in the MMR Text
Area Start as corruption of the row 24 display can occur.
Alternative values are C8H or 49H to overcome this
problem.
The width of the text area is defined in the Text Area End
Register by setting the end character value TAE<5:0>.
This number determines where the background colour of
the Text Area will end if set to extend to the end of the row.
It will also terminate the character fetch process thus
eliminating the necessity of a
row end
attribute. This
entails however writing to all positions.
The vertical offset is set in the Text Position Vertical
Register. The offset value VOL<5:0> is done in number of
TV scan lines.
Note that the Text Position Vertical register should not be
set to 00H as the Display Busy interrupt is not generated
in these circumstances.
19.10 Character set
To facilitate the global nature of the device the character
set has the ability to accommodate a large number of
characters, which can be stored in different matrices.
