19. Display Unit (DU)
Section 19 Display Unit (DU)
19.1
Features
The display unit (DU) has the following features.
Plane: The display surfaces normally called the foreground, background, and cursor, are called
planes in this section. Parameters for each plane can be set independently through the settings of
an internal register. The internal register settings can also be used to set the display priority order.
Combined display of up to six planes is possible (however, the plane size is 480 × 234), when the
plane size is WVGA (854 × 480), up to four planes can be combined, when the plane size is
SVGA: 800 × 600, up to three planes can be combined.
• Display size
• Display position
• Display data format (8 bits/pixel, 16 bits/pixel, ARGB (1555), YC)
• Plane superpositioning
• Scrolling
• Wrap-around
• Blinking
• Buffer control
The internal register settings can be used to select two different control modes.
• Manual display change mode (double buffer)
• Auto display change mode (double buffer)
Synchronization Method: Internal register settings can be used to select any of three
synchronization modes for the display output timing.
• Master mode (internal sync mode)
• TV sync mode (external sync mode)
• Sync method switching mode
