Value
M L
CSCY2R [27]
YCbCr Data Dynamic Range Selection for the Color Space
Conversion YCbCr to RGB
1 = Wide => Y/Cb/Cr (0 ~ 255) : Wide default
0 = Narrow => Y (16 ~ 235), Cb/Cr (16 ~ 240)
1
O O
LCDPathEn [26]
FIFO Mode Enable. 1 for FIFO output and 0 for DMA output.
If FIFO mode enable, Input mode should be DMA input and
WSWP bit at WINCON0(0xEE00_0020) in LCD controller
should be ‘0’.
FIFO mode output format is RGB24bit. its selection depends
on OutFormat register. OutFormat = RGB
→
RGB24bit.
0
O O
Interlace [25]
Output scan method selection register if FIFO mode
(LCDPathEn =1). 1 for Interlace scan and 0 for progressive
scan. In case of DMA output (LCDPathEn = 0), only
progressive scan is applied whatever this value has. This
mode is not allowed if Input image data is from Camera
processor.
0
O X
MainHorRatio [24:16] Horizontal scale ratio for main-scaler 0
O O
ScalerStart [15]
Scaler start
1 = Scaler start
0 = Scaler stop or scaler bypass
0
O O
InRGB_FMT [14:13]
Input DMA RGB format.
00 = RGB565 , 01 = RGB666
10 = RGB888 , 11 = Reserved
0
O X
OutRGB_FMT [12:11]
Output DMA RGB format
00 = RGB565 , 01 = RGB666
10 = RGB888 , 11 = Reserved
0
O O
Ext_RGB [10]
Input RGB data extension enable bit for the conversion of
RGB565/666 mode into RGB888 mode.
1 = Extension , 0 = normal
i) Input R = 5-bit in RGB565 mode
10100 -> 10100101 (Extension) : [7]=[2], [6]=[1], [5]=[0]
10100 -> 10100000 (normal)
ii) Input R = 6-bit in RGB666 mode
101100 -> 10110010 (Extension) : [7]=[1], [6]=[0]
101100 -> 10110000 (normal)
0
O O
One2One [9]
Scaler does not run interpolation but run repetition for
upsampling. Sometimes other IP needs this method if input
format are YCbCr4:2:0 and YCbCr4:2:2. Scalerbypass should
be set ‘0’ and Don’t care plane. (Caution : One2One should
be used if input / output format and size are same)
Ex) input YCbCr4:2:0 2plane -> output YCbCr4:2:0 3plane
