Figure 17-3 OSD Control Registers - 1
OSDCON1
bit 0: STOCK
It controls OSD LC oscillation. If oscillation is stoped,
IC’s power consumption is decreased.
bit 1: DDCLK
If you set this bit to 1, OSD input clock is doubled from LC
oscillation. It makes OSD horisontal image size as dou-
bled.
bit 2: DLINE
If you set this bit to 1, OSD vertical scan counter input
clock is doubled from normal state. It makes OSD vertical
image size as doubled.
bit 7~3: FULLM, I, B, G, R
It controls back ground color as below.
OSDCON2
bit 0: OSDON
It controls OSD, Sprite, Full screen background at once. It
does not affect anything to Vsync interrupt and OSD inter-
rupt, etc.
bit 1: PROSD
It controls screen output priority between sprite and OSD.
If its value is 1, OSD hide sprite pattern in overapped area.
bit 2: ENSP
It enables sprite display.
bit 3: DUSP
It doubles sprite’s horizontal & vertical size during this
value is 1.
bit 4: ONL1
It enables OSD line 1 display. If it is enabled, OSD inter-
rupt is activated.
bit 5: ONL2
It enables OSD line 2 display. If it is enabled, OSD inter-
rupt is activated.
bit 6: OBGW
It controls character’s width. Default width is 12dots. If its
value is set, 2 dots (background color) are added both left
