Table 3-60. AFE Fine Gain for B/Pb
Subaddress 4Ah–4Bh
Default 900h
Subaddress 7 6 5 4 3 2 1 0
4Ah FGAIN 1 [7:0]
4Bh Reserved FGAIN 1 [11:8]
FGAIN 1 [11:0]: This fine gain applies to component B/Pb.
Fine Gain = (1/2048) * FGAIN where 0 ≤ FGAIN 1 ≤ 4095
This register is only updated when the MSB (register 4Bh) is written to.
This register only works in manual gain control mode. When AGC is active, writing to any value is ignored.

Subaddress 7 6 5 4 3 2 1 0
4Ch FGAIN 2 [7:0]
4Dh Reserved FGAIN 2 [11:8]
FGAIN 2 [11:0]: This gain applies to component G/Y channel or S-Video chroma.
This register is only updated when the MSB (register 4Dh) is written to.
This register only works in manual gain control mode. When AGC is active, writing to any value is ignored.
