2.External Display Interface (RGB, VSYNC interfaces)

The R61509V supports RGB and VSYNC interfaces as the external interface to display moving picture.

When the RGB interface is selected, the display operation is synchronized with externally supplied synchronous signals (VSYNCX, HSYNCX, 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 when 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 VSYNCX 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 Section “VSYNC Interface”.

The R61509V allows switching interface by instruction according to the display image (still and/or moving picture). This allows data to be transferred only when the data is updated hence less power consumption during moving picture display.

3.Address Counter (AC)

The address counter (AC) gives an address to the internal GRAM. When the index of a register is written to the IR, the address information is sent from the IR to the AC. After data is written to 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.
