Why is VBLANK and HBLANK polarity wrong for the Constant Interface?

In other words, why do I see active high signals when I select "Valid Signaling" for VBLANK and HBLANK polarity, or why do I see active low signals when I select "Blanking Signaling" for VBLANK and HBLANK polarity when I use the Constant Interface?

解决方案

There is an issue in the Color Filter Array Interpolation v1.0 and v2.0 that only affects the Constant Interface. It is fixed in the Color Filter Array Interpolation v3.0.
