Select Alpha value by
When Per plane blending case( BLD_PIX ==0)
0 = using ALPHA0_R/G/B values
1 = using ALPHA1_R/G/B values
When Per pixel blending ( BLD_PIX ==1)
0 = selected by AEN (A value) or chroma key
1 = using DATA[27:24] data (only when BPPMODE_F = 4'b1101)
Video output and the logic immediately enable/disable.
0 = Disable the video output and the VIDEO control signal.
