When VSYNCDIS=1 (disable VSYNC), the written data is not reflected.
When VSYNCDIS=0 (enable VSYNC), the written data is updated when VSYNC signal rises up.
The register LEDOPDIS, LEDSHDIS, RESSHDIS, MOSSHDIS is update to the newest data when the next VSYNC signal rises
up (positive-edge trigger) after CS positive edge.
The register VSNCDIS is updated to the newest data immediately when the new data is written.
