Notes to VSYNC Interface Operation

1.The above example of calculation gives a theoretical value. Possible causes of variances of internal oscillator should be taken into consideration. Make enough margins in setting RAM write speed for VSYNC interface operation.

2.The above example shows the values when writing over the full screen. Extra margin will be created if the moving picture display area is smaller than that.
