Reserved
0
BLD_PIX
[6]
Select blending category
0 = Per plane blending
1 = Per pixel blending
0
BPPMODE_F
[5:2]
Select the BPP (Bits Per Pixel) mode Window image.
0000 = 1 BPP (LUT )
0001 = 2 BPP (LUT )
0010 = reserved
0011 = reserved
0100 = reserved
0101 = 16 BPP ( non-palletized, R:5-G:6-B:5 )
0110 = 16 BPP ( non-palletized, A:1-R:5-G:5-B:5 )
0111 = 16 BPP ( non-palletized, I :1-R:5-G:5-B:5 )
1000 = unpacked 18 BPP ( non-palletized, R:6-G:6-B:6 )
1001 = unpacked 18 BPP ( non-palletized, A:1-R:6-G:6-B:5 )
1010 = unpacked 19 BPP ( non-palletized, A:1-R:6-G:6-B:6 )
1011 = unpacked 24 BPP ( non-palletized R:8-G:8-B:8 )
1100 = unpacked 24 BPP ( non-palletized A:1-R:8-G:8-B:7 )

ALPHA_SEL
[1]
Select Alpha value by
When ( BLD_PIX ==0)
0 = using ALPHA0_R/G/B values
1 = using ALPHA1_R/G/B values
When ( BLD_PIX ==1)
0 = selected by AEN (A value) or chroma key
1 = using DATA[27:24] data (only when BPPMODE_F = 4’b1101)
