On-Screen Display Configuration
The on-screen display area consists of 12 horizontal rows each containing up to 32 characters.
The correspondence between display data RAM and the screen display is indicated in figure 29.4.
The starting position for display can be set freely by using the display position registers to set the
horizontal starting display position, vertical starting display position, and row interval. Even when
the frequency of the AFC reference clock (dot clock) is modified, the display configuration (12
horizontal rows each containing 32 characters) will not change; characters in the region protruding
outside the display area should be blank characters.
For information on the display position registers, refer to section 29.5.1, Display Positions, and
section 29.5.8, Display Position Registers (HPOS, VPOS).
