ST92186B - ON SCREEN DISPLAY CONTROLLER (OSD)
OSD CONTROLLER (Cont’d)
SHAPE ATTRIBUTE - 18x26 MATRIX
Address in segment 22h: 2p+5+3z. See Figure 52.
Bit 7 = CODX
Character Code Extension
This bit is used as the character address exten-
sion. Then it is possible to address any of the
18x26 characters of the font ROM.
Let’s assume that the character code is ChC[7:0]
(1 byte), then the character addressed with this
structure is: CODX.ChC[7:0]
Bit 6 = DBLY
Double height control bit
This bit controls the double height feature applied
on the current row height.
0: The character is displayed with the current row
height, as defined by SY (Section 7.4.7.3).
1: The current character is displayed with a double
height than defined by SY. The display of the
lower or upper half of the character is controlled
by the UH row attribute bit (refer to Section
7.4.7.3).
Bit 5 = DBLX
Double width control bit
This bit controls the double width feature applied
to the current row character width.
0: The character is displayed with the current width
as defined by SX (Section 7.4.7.3).
1: The character is displayed in double width, ac-
cording to the following rules:
– It covers the next character location
– The next character location is read and de-
coded but not processed,
– If the character is the last one in the row, it will
be truncated to its left half.
Bit 4:0 = Please refer to the bit descriptions in the
9x13 matrix shape attributes.
