TABLE 15. ANALOG INPUT CONTROL REGISTER
SUB ADDRESS = 05
H
BIT
NO.
FUNCTION
DESCRIPTION
RESET
STATE
7-6
Lock Loss
Video Gain
Select
If bits 5-4 do not equal “01”, these bits indicate what mode the AGC circuitry will be after
loss of sync. If bits 5-4 equal “01”, these bits are ignored.
00 = Automatic gain control: bits 5-4 will be reset to “01”
01 = Maintain fixed gain: bits 5-4 will not be changed
10 = Normal AGC switching to fixed gain after lock achieved: bits 5-4 will not be reset to
“01” unless they indicated “freeze automatic gain control”
11 = reserved
00
B
5-4
Video Gain
Control Select
If a value of “10”, the video gain adjust register is used to specify the amount of video gain
to be applied.
00 = Fixed 1x gain
01 = Automatic gain control
10 = Fixed gain control
11 = Freeze automatic gain control
01
B
3
Digital Anti-Aliasing
Filter Control
0 = Internal digital anti-aliasing filter is active.
1 = Internal digital anti- aliasing filter is by-passed.
0

Input Select
000 = NTSC/PAL 1
001 = NTSC/PAL 2
010 = NTSC/PAL 3
011 = S-video
100 = reserved
101 = reserved

TABLE 16. COLOR PROCESSING REGISTER
SUB ADDRESS = 06
H
BIT
NO.
FUNCTION
DESCRIPTION
RESET
STATE
7-6
Color Gain
Control Select
If a value of “10”, the color gain adjust register is used to specify the amount of color gain
to be applied.
00 = No gain control (gain = 1x)
01 = Automatic gain control
10 = Fixed gain control
11 = Freeze automatic gain control
01
B
5-4
Color Killer
Select
00 = Force color on
01 = Enable color killer
10 = reserved
11 = Force color off
01
B
3-2
Color Coring
Select
Coring may be used to reduce low-level noise around zero (code 128) in the CbCr signals.
00 = No coring
01 = 1 code coring
10 = 2 code coring
11 = 3 code coring
00
B
1
Contrast Control
Select
This bit specifies whether the contrast control affects just the Y data (“0”) or both the Y
and CbCr data (“1”). To avoid color shifts when changing contrast, this bit should be a “1”.
0 = Contrast controls only Y data
1 = Contrast controls Y and CbCr data
1
B
0
Color Lowpass
Filter Select
This bit selects the bandwidth of the CbCr data.
0 = 850kHz
1 = 1.5MHz
0
