FMARK Interface

In the FMARK interface operation, data is written to internal RAM via system interface synchronizing with the frame mark signal (FMARK), realizing tearing less video image while using conventional system interface. FMARK output position is set in units of line using FMP bit. Set the bit considering data transfer speed.

In this operation, moving picture display is enabled via system interface by writing data at higher than the internal display operation frequency to a certain degree, which guarantees rewriting the moving picture RAM area without causing flicker on the display.

The data is written in the internal RAM. Therefore, when moving picture is displayed, data is written only to the moving picture display area without using RGB or VSYNC interface, minimizing number of data transfer required for moving picture display.
