Weak signal detection:
0 = No weak signal
1 = Weak signal mode
PAL switch polarity of first line of odd field:
0 = PAL switch is 0b
1 = PAL switch is 1b
Field sequence status:
0 = Even field
1 = Odd field
Color killed:
0 = Color killer not active
1 = Color killer activated
Macrovision detection [2:0]:
000 = No copy protection
001 = AGC pulses/pseudo syncs present (Type 1)
010 = 2-line colorstripe only present
011 = AGC pulses/pseudo syncs and 2-line colorstripe present (Type 2)

Fine gain [11:0]:
This register provides the fine gain value of sync channel.
1111 1111 1111 = 1.9995
1000 0000 0000 = 1
0010 0000 0000 = 0.5
Coarse gain [3:0]:
This register provides the coarse gain value of sync channel.
1111 = 2
0101 = 1
0000 = 0.5
The AGC gain status register is updated automatically by the TVP5146M2 decoder when AGC is on. In manual gain control mode, these
register values are not updated by the TVP5146M2 decoder.
