AC = acknowledge bit (= 0) generated by the TDA8440
D7 = 1 audio la is selected to audio output a
D7 = 0 audio la is not selected
D6 = 1 audio lla is selected to audio output a
D6 = 0 audio lla is not selected
D5 = 1 audio lb is selected to audio output b
D5 = 0 audio lb output is not selected
D4 = 1 audio llb is selected to audio output b
D4 = 0 audio llb is not selected
D3 = 1 video l is selected to video output
D3 = 0 video l is not selected
D2 = 1 video ll is selected to video output
D2 = 0 video ll is not selected
D1 = 1 video amplifier gain is times 2
D1 = 0 video amplifier gain is times 1
D0 = 1 OFF-input inactive
D0 = 0 OFF-input active
STO = stop condition
OFF FUNCTION
With the OFF input all outputs can be switched off (mode high ohmic), depending on the value of D0.
