ST92186B - ON SCREEN DISPLAY CONTROLLER (OSD)
OSD CONTROLLER (Cont’d)
7.4.6.2 Underline Color Set 2 (UCS2)
Address in Segment 22h: 06h (Bits 15:8), 07h (Bits 7:0)
Bits 15:12 = Free for the user
Bits 11:9 = U2T[2:0]
Underline color set 1 Translu-
cency
These bits configure the background translucency
level applied to the color (refer to Section 7.4.3.11
for more details).
U2T[2:0] = 7 means that this color will be fully
opaque (no video mixed in it on the display)
U2T[2:0] = 0 means that this color will be fully
transparent (the video is displayed instead of this
color)
Bits 8:6 = U2R[2:0]
Underline color set 1 Red
color
These bits configure the background red intensity
for the color.
U2R[2:0] = 0 means that no red is used to define
the color.
U2R[2:0] = 7 means that the maximum red intensi-
ty is used in the color.
Bits 5:3 = U2G[2:0]
Underline color set 1 Green
color
These bits configure the background green inten-
sity for the color.
U2G[2:0] = 0 means that no green is used to de-
fine the color.
U2G[2:0] = 7 means that the maximum green in-
tensity is used in the color.
Bits 2:0 = U2B[2:0]
Underline color set 1 Blue
color
These bits configure the background blue intensity
for the color.
U2B[2:0] = 0 means that no blue is used to define
the color.
U2B[2:0] = 7 means that the maximum blue inten-
sity is used in the color.
Warning: The UCS1 and UCS2 data may be used
as “row attributes” providing more than 3 underline
colors on screen. This requires taking some care
when their contents are modified.
The UCS1 and UCS2 contents are fetched for dis-
play only when dot lines 12/13 of the character are
being processed, but at that time (while dot lines
12 and 13 are processed) any change to UCS1 or
UCS2 is forbidden.
Software should change the UCS1 or UCS2 while
the display processes character dot lines 1 to 11. It
is recommended to associate the UCS1 or UCS2
management of the currently displayed buffer with
the routine which handles the next buffer prepara-
tion. Refer to Section 7.4.7.9.
