(4) Border
The border is output around the character font (all bordered) in the
OSD2 mode only. The border ON/OFF is controlled by bit 0 and 1 of
block control register i (refer to Figure 8.10.4).
The OUT signal is used for border output.
The horizontal size (x) of the border is 1TC (OSD clock cycle divided
in pre-divide circuit) regardless of the character font dot size. The
vertical size (y) differs depending on the screen scan mode and the
vertical dot size of the character font.
Notes 1 : The border dot area is the shaded area as shown in Figure 8.10.21.
2 : When the border dot overlaps on the next character font, the charac-
ter font has priority (refer to Figure 8.10.23 A).
When the border dot overlaps the next character back ground, the
border has priority (refer to Figure 8.10.23 B).
3 : The border in vertical out of the character area is not displayed (refer
to Figure 8.10.23).
