PRELIMINARY
Notice: This is not a final specification.
Some paramentic limits are subject to change.
MITSUBISHI MICROCOMPUTERS
(10) Attribute
The attributes (flash, underline, italic) are controlled to the character
font. The attributes for each character are specified by the color codes
1 and 2 (refer to Figure 71). The attributes to be controlled are differ-
ent depending on each mode.
CC mode .....................Flash, underline, italic
OSD mode ..................Border (all bordered, shadow bordered can
be selected)
EXOSD mode .............Border (all bordered, shadow bordered can
be selected) , extra font (16 kinds)
The underline is output at the 23th and 24th dots in vertical direction
only in the CC mode. The underline is controlled by bit 6 of color
code 1. The color of underline is the same color as that of the char-
acter font.
The parts of the character font, the underline, and the character back-
ground are flashed only in the CC mode. The color signals (R, G, B,
OUT1) of the character font and the underline are controlled by bit 5
of color code 1. All of the color signals for the character font flash.
However, the color signal for the character background can be con-
trolled by bit 3 of the OSD control register (refer to Figure 64). The
flash cycle bases on the V
SYNC
count.
· V
SYNC
cycle 5 48 ; 800 ms (at flash ON)
· V
SYNC
cycle 5 16 ; 267 ms (at flash OFF)
The italic is made by slanting the font stored in OSD ROM to the right
only in the CC mode. The italic is controlled by bit 7 of color code 1.
The display example of the italic and underline is shown in Figure 85.
In this case, “R” is displayed.
Notes 1:
When setting both the italic and the flash, the italic charac-
ter flashes.
2:
When the pre-divide ratio = 1, the italic character with slant
of 1 dot 5 5 steps is displayed (refer to Figure 84 (c)). When
the pre-divide ratio = 2, the italic character with slant of 1/2
dot 5 10 steps is displayed (refer to Figure 84 (d)).
3:
The boundary of character color is displayed in italic. How-
ever, the boundary of character background color is not af-
fected by the italic (refer to Figure 85).
4:
The adjacent character (one side or both side) to an italic
character is displayed in italic even when the character is
not specified to display in italic (refer to Figure 85).
5:
When displaying the italic character in the block with the
pre-divide ratio = 1, set the OSD clock frequency to 11 MHz
to 14 MHz.
