Extra font
There are 16 kinds of the extra fonts configured with 16 ! 26 dots in
OSD ROM. This 16 kinds fonts can be displayed by ORed with the
character font by a character unit (refer to Figure 62). In only the
EXOSD mode, the extra font is controlled the following : bits 7 to 5 of
the color code 1 and bit 3 of the color code 2.
The extra font color for each screen is specified by the extra color
register. When the character font overlaps with the extra font, the
color of the area becomes the ORed color of both fonts.

Notes 1 : When using the extra font, set bits 7 and 6 of the OSD
control register to “0” (refer to Figure 64).
2 : Extra fonts are always displayed by ORed with the char-
acter font. Accordingly, when displaying only a extra font,
set a blank for a character font and OR with it.
