Preliminary product information describe products that are in development,
for which full characterization data and associated errata are not yet available.
Specifications and information herein are subject to change without notice.
0010 = 4 BPP
0011 = 8 BPP ( palletized )
0100 = 8 BPP ( non-palletized, A: 1-R:2-G:3-B:2 )
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 )
1101 = unpacked 25 BPP ( non-palletized A:1-R:8-G:8-B:8 )
111x = reserved
Note. 1101 can support unpacked 28 BPP also ( non-palletized
A:4-R:8-G:8-B:8 ) ,at BLD_PIX = 1.
ALPHA_SEL
[1]
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)
0
ENWIN_F
[0]
Video output and the logic immediately enable/disable.
0 = Disable the video output and the VIDEO control signal.
1 = Enable the video output and the VIDEO control signal.
