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
These AGC gain status registers are updated automatically by the TVP5147 decoder with AGC on. In manual
gain control mode, these register values are not updated by the TVP5147 decoder.
