Source image format for MSDMA
00 : YCbCr 4:2:0
01 : YCbCr 4:2:2 (non-interleave)

ENVID_M_C

MSDMA operation start. (When triggered Low to High by
software setting) Hardware doesn’t clear automatically
This register is allowed set only Software Trigger mode. If
Hardware trigger mode, this bit is read only.
1) SEL_DMA_CAM = ‘0’ , ENVID don’t care (using external
camera signal for codec path)
2) SEL_DMA_CAM = ‘1’, ENVID is set (0

operation start for codec.

Note: ENVID_M_C SFR must be set at last. Starting order for using MSDMA input path.
