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 12.11.1 shows the configuration of OSD character display area.
Figure 12.11.2 shows the block diagram of the OSD circuit. Figure
