I/O
Video data inputs.
The input video data are the luma (Y) data as defined in CCIR Rec 601 in 16-bit CCIR601 mode.
In the Y/U/V output mode, the output is 10-bit luma signal with a composite sync.
In 16-bit CCIR601 mode, an MSB and LSB is VD7 and VD0, and in the Y/U/V output mode, VD9 and
VD0, respectively.
