INPUT DATA FORMAT
1) Input Level 1 (YCbCr format)
The signal level specified by the ITU-R BT.601 is input.
When other signal levels than specified by the ITU-R BT.601 are input, the luminance signal level
is clipped to 16 to 254 and the chrominance signal level to 1 to 254.
For chrominance signal input, the offset binary or 2's complement format is available by setting
of internal register MR0[6].
2) Input Level 2 (RGB format)
Two types of input level are available by setting of internal register MR1[5].
