Address 05h
7 6 5 4 3 2 1 0
Reserved Reset
Reset:
0 = Normal operation (default)
1 = Reset device
3.22.7 Color Killer Threshold Control Register
Address 06h
7 6 5 4 3 2 1 0
Reserved Automatic color killer Color killer threshold
Automatic color killer:
00 = Automatic mode (default)
01 = Reserved
10 = Color killer enabled, the UV terminals are forced to a zero color state.
11 = Color killer disabled
Color killer threshold:
11111 = −30 dB (minimum)
10000 = −24 dB (default)
00000 = −18 dB (maximum)
3.22.8 Luminance Processing Control #1 Register
Address 07h

Luma bypass mode Pedestal not present
Disable raw
header
Luma bypass during
vertical blank
Luminance signal delay with respect to
chrominance signal
Luma bypass mode:
0 = Input video bypasses the chroma trap and comb filters. Chroma outputs are forced to zero (default).
1 = Input video bypasses the whole luma processing. Raw A/D data is output alternatively as UV data and
Y data at SCLK rate. The output data is properly clipped to comply to ITU−R BT.601 coding range. Only
valid for 8-bit YUV output format (YUV output format = 100 or 111 at register 0Dh).
Pedestal not present:
0 = 7.5 IRE pedestal is present on the analog video input signal (default).
1 = Pedestal is not present on the analog video input signal.
Disable raw header:
0 = Insert 656 ancillary headers for raw data.
1 = Disable 656 ancillary headers and instead force dummy ones (0x40) (default).
Luminance bypass enabled during vertical blanking:
0 = Disabled (default)
1 = Enabled
Luminance bypass occurs for the duration of the vertical blanking as defined by registers 18h and 19h. This
feature may be used to prevent distortion of test and data signals present during the vertical blanking interval.
