2. External Display Interface (RGB, VSYNC Interfaces)
The R61505 supports RGB interface and VSYNC interface as the external interface to display moving
picture. When the RGB interface is selected, the display operation is synchronized with externally supplied
signals, VSYNC, HSYNC, and DOTCLK. In RGB interface operation, data (DB17-0) is written in
synchronization with these signals when the polarity of enable signal (ENABLE) allows write operation in
order to prevent flicker while updating display data.
In VSYNC interface operation, the display operation is synchronized with the internal clock except frame
synchronization, which synchronizes the display operation with the VSYNC signal. The display data is
written to the internal GRAM via system interface. When writing data via VSYNC interface, there are
constraints in speed and method in writing data to the internal RAM. For details, see the “VSYNC
interface” section.
The R61505 allows switching interface by instruction according to the display, i.e. still and/or moving
picture(s). The R61505 writes all display data via RGB interface to the internal GRAM in order to transfer
data only when updating the data and thereby reduce the data transfer and power consumption for moving
picture display.
3. Address Counter (AC)
The address counter (AC) gives an address to the internal GRAM. When the index of the register to set a
RAM address in the AC is written to the IR, the address information is sent from the IR to the AC. As the
R61505 writes data to the internal GRAM, the address in the AC is automatically updated plus or minus 1.
The window address function enables writing data only within the rectangular area specified in the GRAM.
