Description
This ROP determines if results of component color keying are true
or not. Keys to the ROP are range_match upper, middle, lower.
Upper match is key2, middle match is key1, lower match is key0.

Phase coefficient
Differential phase coefficient
For the interpolator to work in bypass mode this register has to be
programmed to 0
Unsigned. This delta phase is added with phase with every output
data. Once phase is added with a certain number of d_phases to
get overflowed, then it’s time shift input sample signals.
For the HSRU to work in bypass mode this register has to be
programmed to 0.
Example:
8000 (hex) => upscaling by 2
4000 (hex) => upscaling by 4
Unsigned. This is the initial phase of input pixel phase. It determines
the portions of the first input samples used to generate output
pixels.
0 = Color key didn’t match.
1 = Color key matched.
0 = Color key didn’t match.
1 = Color key matched.
0 = Color key didn’t match.
1 = Color key matched.
0 = Color key didn’t match.
1 = Color key matched.
