ST92186B - ON SCREEN DISPLAY CONTROLLER (OSD)
OSD CONTROLLER (Cont’d)
7.4.7.3 Row Attributes
Address in Segment 22h: 2p + 4. See Figure 52.
For each row to be displayed, specify the font ma-
trix used (9x13 or 18x26), the size of the charac-
ters, the rounding, the fringe and the flash mode.
Let’s assume that the start address of the current
row buffer is 2p (even address).
Bit 7 = FM
Font Matrix
This bit selects the 9x13 or the 18x26 font matrix
for the current row.
The FM bit is not an address extension bit but it af-
fects how the Font ROM content is addressed.
0: the characters use a 9x13 font matrix.
1: the characters use an 18x26 font matrix
Bit 6 = UH
Upper Half
When 18x26 characters are displayed in double
height (i.e. if the DBLY parallel attribute is set), the
UH bit defines if the current row displays the lower
or upper half of the character.
This bit has no effect when a 9x13 matrix is used
or when the character has normal height (when
DBLY= 0).
0: the lower half of the double-height character is
displayed.
1: the upper half of the double-height character is
displayed.
Bit 5 = Free for the user
Bit 4 = SY
Vertical Size control bit
This bit defines the character Dot height
Refer to Table 20, Table 21, and Table 22 for com-
plete details.
Note: The dot height is also affected by DBLY, de-
fined in the parallel attribute section.
Bit 3 = SX
Horizontal Size control bit
This bit defines the character Dot width
Refer to Table 20, Table 21, and Table 22 for com-
plete details.
Note: The dot width is also affected by DBLX, de-
fined in the parallel attribute section.
Table 20. 9x13 Font Matrix
Table 21. 18x26 Font Matrix (1)
Table 22. 18x26 Font Matrix (2)
Note: In 18x26 matrix mode, this mechanism pro-
vides 7 different sizes which are: 1Y-1X, 2Y-2X,
4Y-4X but also 2Y-1X, 1Y-2X, 4Y-2X, 2Y-4X.
Note: When the Display controller works in basic
parallel mode, the DBLX and DBLY bits are not ac-
cessible, and are assumed to be always pro-
grammed to “0”.
Bit 2 = FON
Flash ON control bit
This bit is used to control the flashing period by
software. It is only available in serial and extended
parallel modes. This bit has no effect in basic par-
allel mode.
0: the flashing mechanism is disabled for the
whole row in all modes.
1: the flashing mechanism is enabled for the whole
row. All characters described in the row with a
serial or a parallel flash attribute are displayed
as space with background color. Underline also
flashes.
