L1VPOS
It shows OSD line 1’s vertical position in 9bit format
(LIV8 + L1VPOS, 000 ~ 1FF
H
).
Figure 17-8 OSD Registers - 5
Figure 17-9 OSD Register - 6
L2ATTR
It controls OSD line 2’s attributes. Its function is the same
as L1ATTR.
L2VPOS
It shows OSD line 2’s vertical position. Its function is the
same as L1VPOS.
COLMOD
It controls OSD output mode-RGB direct half intencity.
Figure 17-10 OSD Register - 7
bit 0: C16EN
It enables RGB port half intencity output. When this bit is
set, RGB port generates half intencity output. Half intenci-
ty output is 3.5V voltage level output of RGB port. When
you use this bit, you must fill all the other bit with ‘0’.
Note:
When you do not use RGB direct half intncsity out-
put , please initialize this register as 00h.
MESHCON
It controls OSD mesh mode color.
Figure 17-11 OSD Register - 8
Note:
Please initialize this register as 00h. Though this
register is for mesh mode color, it is not used currently.
VRAM
VRAM contains 1 OSD line, 24 character’s attributes.
Each character’s attribute is constructed with 3 bytes, it
contains color data for background, shadow, outline, char-
acter and character number ( 000
