(4) Border
The border is output only in the OSD mode. The all bordered
(bordering around of character font) and the shadow bordered
(bordering right and bottom sides of character font) are selected
(refer to Figure 8.11.32) by bit 2 of the OSD control register 1
(refer to Figure 8.11.3). The ON/OFF switch for borders can be
controlled in block units by bit 2 of the block control register i
(refer to Figure 8.11.4).
The OUT1 signal is used for border output. The border color is
fixed at color code 8 (block). The border color for each screen is
specified by the border color register i.
Fig. 8.11.32 Example of Border Display
Fig. 8.11.33 Horizontal and Vertical Size of Border
The horizontal size (x) of border is 1TC (OSD clock cycle divided
in the pre-divide circuit) regardless of the character font dot size.
However, 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: The border dot area is the shaded area as shown in
Figure 8.11.34.
2: When the border dot overlaps on the next character font, the charac-
ter font has priority (refer to Figure 8.11.35 A). When the border dot
overlaps on the next character back ground, the border has priority
(refer to Figure 8.11.35 B).
3: The border in vertical out of character area is not displayed (refer to
Figure 8.11.35).
