Objective specification
Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA567x; SAA569x
Status read
BUSY
DISP FIELD
access to Display memory could cause display problems (logic 1)
Display Field identification, derived from H&V syncs, even field (logic 1). In basic
Progressive Scan mode the hardware will force this bit to toggle every Vsync enabling the
software to distinguish a notional field.
active flash region background only displayed (logic 1)
first scroll row
FLR
SCR3 to SCR0
Status write
SCON
FLR
SCR3 to SCR0
scroll area enabled (logic 1)
active flash region background colour only displayed (logic 1)
first scroll row
HSYNC Delay
HSD6 to HSD0
HSYNC delay; in full size characters
VSYNC Delay
VSD6 to VSD0
VSYNC delay in number of 8-bit 12 MHz clock cycles
Top Scroll Line
SCL3 to SCL0
top line for scroll
Configuration
CC
VDEL2 to VDEL0
Closed Caption mode (logic 1)
pixel delay between VDS and RGB output
000 = VDS switched to video, not active
001 = VDS active one pixel earlier then RGB
010 = VDS synchronous to RGB
100 = VDS active one pixel after RGB
BUSY signal switch; horizontal (logic 1)
Acquisition Field identification; based on the selected CVBS signal and independent from
the display sync signals
100 Hz mode select; 100 Hz/120 Hz timing mode (logic 1)
two page mode select; dual page (logic 1)
TXT/V
ACQ FIELD
100 Hz
Two_Page
Text Area Start B
HOP1 to HOP0
TAS5 to TAS0
fine horizontal offset in quarter of characters
text area start
Text Area End B
TAE5 to TAE0
text area end, in full characters
Page B Position
PGB7 to PGB0
Page B position
Text Position Vertical B
VOLB5 to VOLB0
Page B display start vertical offset from VSYNC (lines) should equal VOL5 to VOL0 in
double window mode (MMR 87F1H<5:0>)
