2.16.10 Attribute
The attributes (flash, underline, italic fonts) are controlled to the character font. The attributes for each
character are specified by RC14 to RC16 of OSD RAM (refer to Figure 2.16.26). The attributes to be
controlled are different depending on each mode.
CC mode ................... Flash, underline, italic for each character
OSDS/P mode .......... Border (all bordered, shadow bordered can be selected) for each block
The display example attribute is shown in Figure 2.16.33. In this case, “R” is displayed.
(1) Under line
(2) Flash
(3) Italic
The underline is output at the 23rd and 24th lines in vertical direction only in the CC mode. The
underline is controlled by RC16 of OSD RAM. The color of underline is the same color as that of the
character font.
The parts of the character font, the underline, and the character background are flashed only in the CC
mode. The flash for each character is controlled by RC15 of OSD RAM. The ON/OFF for flash is
controlled by bit 3 of the OSD control register 1 (refer to Figure 2.16.3). When this bit is “0, ” only

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 RC14 of OSD RAM.
