    Never pass
    Never passes.
    Alpha < value
    Passes when Pixel alpha < Reference value.
    Alpha <= Value
    Passes when Pixel alpha <= Reference value.
    Alpha == Value
    Passes when Pixel alpha == Reference value.
    Alpha != Value
    Passes when Pixel alpha != Reference value.
    Alpha >= Value

    Alpha > Value
    Passes when Pixel alpha > Reference value.
    Always passes
    Always passes.

  2. Sets blend mode.

    None.
    Does no blend processing, and the pixel value is loaded into eFB without modification.
    Blend calculations
    Blends based on the blend formula.
    Details on configuration are given in Blend Calculation Mode.
    Logic calculations
    Logically calculates the pixel value and the frame buffer value and writes it.
    Details on configuration are given in Logic Calculation Mode.

    Calculation result=0.
    1
    Calculation result=1.
    Pixel Color
    Calculation result=pixel color.
    ~Pixel color
    Calculation result=~pixel color.
    eFB Color
    Calculation result=Framebuffer color.
    ~eFB color
    Calculation result=~Framebuffer color.
    Pixel color & eFB color
    Calculation result=Pixel color & framebuffer color.
    ~(Pixel color & eFB color)
    Calculation result=~Pixel color & framebuffer color)..
    Pixel color | eFB color
    Calculation result=Pixel color | framebuffer color.
    ~(Pixel color | eFB color)
    Calculation result=~(Pixel color | framebuffer color).
