Objective specification
Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA56xx
23.10.2 D
OUBLE WINDOW MODE
The display (see Fig.40) consists of the
two screen
colours
covering each half of the screen and two
text
areas
that are placed within the visible screen area. The
screen colour extends over a large vertical and horizontal
range so that no offset is needed. Both text areas are
offset in both directions relative to the vertical and
horizontal sync pulses.
The second page may be positioned relative to HSYNC
delay using the Page B Position MMR.
The visible text area for Page A is controlled using the
Text Area Start and Text Area End MMRs. Page B visible
text area is controlled using the Text Area Start B and
Text Area End B MMRs.
