[14:0] Horizontal offset in the source image
- (11.4) format
* For source image cropping,
VP_SRC_H_POSITION + VP_SRC_WIDTH
should be less than or equal to
VP_IMG_HSIZE_Y
Note: (11.4) format means that
- '11' is an integer.
- '4' is a fraction.
Example) In case of H Position = 4
4(0x4(h) = 0100(b)) is integer. Due to 4-bit
fraction, 0100(b) is had to do 4 time left shift
operation. As a result, register value is 4 * 2^4 =
64 = 0x40.
Bit
[31:10] Reserved, read as zero, do not modify
[10:0] Vertical offset in the source image.
This value should be in the range between 0 and
VP_SRC_HEIGHT.
If LINE_SKIP is 1, VP_SRC_V_POSITION should
be a half of that if LINE_SKIP is 0.
Bit
[31:11] Reserved, read as zero, do not modify
[10:0] Width of the source image
