Border
The border is output in the OSD mode and the EXOSD mode. The all
bordered (bordering around of character font) and the shadow bor-
dered (bordering right and bottom sides of character font) are se-
lected (refer to Figure 77) by bit 2 of the OSD control register (refer to
Figure 55). The border ON/OFF is controlled by bit 2 of the block
control register (refer to Figure 56).
The OUT1 signal is used for border output. The border color for each
screen is specified by the border color register.
The horizontal size (x) of border is 1TC (OSD clock cycle divided in
the pre-divide circuit) regardless of the character font dot size. How-
ever, only when the pre-divide ratio = 2 and character size = 1.5TC,
the horizontal size is 1.5TC. The vertical size (y) different depending
on the screen scan mode and the vertical dot size of character font.
Notes 1 : There is no border for the extra font.
2 : The border dot area is the shaded area as shown in Figure
79. In the EXOSD mode, top and bottom of character font
display area is not bordered.
3 : When the border dot overlaps on the next character
font, the character font has priority (refer to Figure 80 A).
When the border dot overlaps on the next character back
ground, the border has priority (refer to Figure 80 B).
4 : The border is not displayed at right side of the most right
dot in the display area of the 36th character (the character
located at the most right of the block).
However, note that EPROM version can display the bor-
der above when programming.
(The border for the right edge dots of the 40th’s character
area is not displayed.)
