Switches output gain.
Switches output gain.
Remark: GAIN = 01 (-3 dB) 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.
Changes CbCr4-IN pins function.
Switches Y1 (2, 3, 4) clamping mode.
Turns on the delay to FB1 (2)-OUT (pin 9 (22)).
Mutes FB1 (2)-OUT (pin 9 (22)).
Switches the output from FB1(2)-OUT (pin 9 (22)).
Switches audio outputs from AL/AR1 (2,3)-OUT (pins 5/7 (18/20, 1/3)).
Gain of CVBS1(2)-OUT output (pin 4 (17)) is controlled.
Gain of YCbCr1(2)-OUT outputs (pins 6,8,10 (19, 21, 23)) are controlled.
The clamping mode for pin 49 (69, 55, 75) is set.
