The register values after reset are as follows:
Yred = 10’h254 (596/512 = 1.16)
Crred = 11’h331 (817/512 = 1.6)
Cbred = 12’h000
Ygreen = 10’h254(596/512 = 1.16)
Crgreen = 11’h660(-416/512 = -0.812)
Cbgreen = 12’hf38(-200/512 = -0.39)
Yblue = 10’h254(596/512 = 1.16)
Crblue = 11’h000
Cbblue = 12’h409(1033/512 = 2.017)
