When the input has fewer lines than
this value, it is considered as an
ERROR, and INPUT_X status bit
will be HIGH.

Description
120H Low water mark for valid data
If the data is smaller than this threshold, it is
considered LOW internally
121H High water mark for valid data
If the data is larger than this threshold, it is considered
HIGH internally
122H Minimum difference between the data value of two
adjacent pixels to be considered as an edge
123H [1:0] This is to select different operation modes of internal
phase calibration. The selection criterion is as follow:
0: when input video signal has large overshot,
it results in longest calibration time
1: when input video signal has median overshot,
it results in long calibration time
2: when input video signal has normal overshot,
it results in normal calibration time
(recommended)
3: when input video signal has no overshot,
it results in shortest calibration time
124H-125H Upper bound of the line number for 640x350 mode,
and lower bound for 640x400
126H-127H Upper bound of the line number for 640x400 mode,
