MSCTRLn Bit Description R/W Initial State
SEL_DMA_
CAM [3] Selects input data selection.
0 = External camera input path
1 = Memory data input path (Input DMA)
(ML=OX) R/W 0
InFormat_M [2:1] Specifies the source image format for input DMA.
00 = YCbCr 4:2:0 input image format. (2 or 3 plane)
01 = YCbCr 4:2:2 input image format. (2 or 3 plane)
(ref. 2 or 3 plane format register
→ C_INT_IN)
10 = YCbCr 4:2:2 input image format. (1 plane)
11 = RGB input image format. (ref. RGB format register
→
InRGB_FMT)
Note) Refer to the gathering extension register.
YCbCr444_IN
(ML=OX)
R/W 0
ENVID_M [0] Starts input DMA operation (Software setting triggers low to
high). The hardware clears automatically. If data flows from
input DMA to local direct FIFO, the software can clear this
bit when LCD_ENSTATUS is ‘0’.
1) SEL_DMA_CAM = ‘0’, ENVID_M don’t care (using
external camera signal)
2) SEL_DMA_CAM = ‘1’, ENVID_M is set (0
→
1), then
Input DMA operation starts
(ML=OX)
R/W 0
NOTE:
ENVID_M SFR must be set at the end. Starting order for using DMA input path.
SEL_DMA_CAM (others SFR setting) → Image Capture Enable and Scaler start SFR setting → ENVID_M SFR
setting.
