Switches output gain.
Remark: GAIN = 01 (-3dB) is recommended for the 1125/50p/60p format since this
Changes CbCr1-IN pins function.
Changes CbCr2-IN pins function.
Changes CbCr3-IN pins function.
Switches Y1 (3)/G1(G3) & Cr1(3)/R1(3) clamping mode.
Switches Y2 clamping mode.
TEST modes for shipping test. Set all to zero.
Switches audio outputs from AL/AR1 (2)-OUT (pins 3/5 (13/15)).
Switches output gain.
Gain of CVBS / Y / G OUT outputs (pins 2) is controlled.
Gain of CbCr(B/R) OUT outputs (pins 4,6) is controlled.
The clamping mode for pin 40(58) & pin 36(54) is set.
The clamping mode for pin 52 is set.

Remark: GAIN = 01 (-3dB) is recommended for the 1125/50p/60p format since
this offers superior frequency characteristics to those of other modes.
