Product data sheet
Since each layer can have four color keys, the output is a 4-bit vector specifying
which keys match the pixel. This 4-bit vector is masked by the ColorKeyMASK. The
result is Key1. For Key3 the procedure is similar, with the only difference being the
color key vector is passed from the previous mixer. The result of masking the color
key vector with the ColorKeyMask register is Key3. However, one can do selective
color keying for the current pixel. A ColorKeyROP specifies whether color keying is
performed on the current layer pixel or not. Inputs for this ROP are Key0,1,2, 3.
The ROP block decides if a certain operation is done on the pixel or not.
The outputs of the Select, Alpha, Invert, Key_Pass and Alpha_pass ROPs are based
on Raster operations as shown in
Table 4: ROP Table for Invert/Select/Alpha/KeyPass/AlphaPass ROPs

signals which are used to control the actual pixel manipulation functions shown in
Table
Remark: For mixer 1 there is no previous mixer and therefore the corresponding
inputs are set to 0.
