The OSD circuit has an extended display mode. This mode allows
multiple lines (16 lines or more) to be displayed on the screen by
interrupting the display each time one line is displayed and rewriting
data in the block for which display is terminated by software.
Figure 53 shows the configuration of OSD character. Figure 54 shows
the block diagram of the OSD circuit. Figure 55 shows the structure
of the OSD control register. Figure 56 shows the structure of the
block control register.
