R61509V

Target Spec

RGB interface operation (2)

This mode enables the R61509V to rewrite RAM data via system interface while using RGB interface for display operation. To rewrite RAM data via system interface, make sure that display data is not transferred via RGB interface (ENABLE = high). To return to the RGB interface operation, change the ENABLE setting first. Then set an address in the RAM address set register and R22h in the index register.

VSYNC interface operation

The internal display operation is synchronized with the frame synchronous signal (VSYNCX) in this mode. This mode enables the R61509V to display a moving picture via system interface by writing data in the internal RAM at faster than the calculated minimum speed via system interface from the falling edge of frame synchronous (VSYNCX). In this case, there are restrictions in speed and method of writing RAM data. For details, see the “VSYNC Interface” section.

As external input, only VSYNCX signal input is valid in this mode. Other input via external display interface becomes disabled.

The front porch (FP), back porch (BP), and the display (NL) periods are automatically calculated from the frame synchronous signal (VSYNCX) inside the R61509V according to the instruction settings for these periods.

FMARK interface operation

In the FMARK interface operation, data is written to internal RAM via system interface synchronizing with the frame mark signal (FMARK), realizing tearing-less moving picture while using conventional system interface. In this case, there are restrictions in speed and method of writing RAM data. See “FMARK interface” for detail.
