WINCON4 Bit Description Reset Value
BITSWP [18] Bit swap control bit.
0 = Disables Swap 1 = Enables Swap 0
BYTSWP [17] Byte swaps control bit.
0 = Disables Swap 1 = Enables Swap 0
HAWSWP [16] Half-Word swap control bit.
0 = Disables Swap 1 = Enables Swap 0
WSWP
[15]
Word swap control bit.
0 = Disables Swap 1 = Enables Swap
Reserved [14:11] Reserved (should be 00) 0
BURSTLEN [10:9] DMA’s Burst Maximum Length selection :
00 = 16 word– burst
01 = 8 word– burst
10 = 4 word– burst
0
Reserved [8] Reserved (should be 0) 0
ALPHA_MUL [7] Multiplied Alpha value mode
0 = Disables
1 = multiplied mode
If ALPHA_MUL is 1, you should set BLD_PIX =1 , ALPHA_SEL=1
and ( BPPMODE_F[5:2] = 4’b1101 or 4’b1110 )
Note . i ) Alpha value = alpha_pixel(from data) * ALPHA0_R/G/B
ii ) In this mode,
you can only select two cases @BLENDEQ4
- A_FUNC = alphaA, B_FUNC = 1 – alphaA
- A_FUNC = alphaA, B_FUNC = max (pre-multiplied)
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
0001 = 2 bpp
0010 = 4 bpp
0011 = 8 bpp ( palletized )
