CAMERA INTERFACE
MSDMA FEATURE
MSDMA supports memory data scaling. Especially two different image data is required for PIP (Picture-in-Picture)
operation. First image is saved memory by some codec(H.264 , Camera , MPEG4 etc.) Second image is saved
memory through MSDMA path. The MSDMA path has YCbCr/RGB output format through scaler/dma path. Two
images are displayed and controlled by LCD controller. If MSDMA is (reading the memory data) required to use in
preview path or codec path. SFR SEL_DMA_CAM_P(=SEL_DMA_CAM_C) signal must be set '1'. This input path
is called Memory Scaling DMA path. This path is not allowed windowing zoom function.
Note: Memory image format for MSDMA input are:
1) YCbCr 4:2:0 (non-interleave)
2) YCbCr 4:2:2 (non-interleave)
3) YCbCr 4:2:2 (Interleave)
4) RGB

※ The last 'L' column means that SFR can change at vsync edge during camera capturing. (O : possible
change, X : impossible change). Also, 'M' column means that SFRs have relationship capturing result
during using MSDMA path. (O : relationship, X : no relationship)
