5 / 12 page November 1985 5 Philips Semiconductors Product specification Switch for CTV receivers TDA8440 I2C BUS CONTROL Detailed information on the I2C bus is available on request. Table 2 TDA8440 I2C bus protocol. OFF FUNCTION With the OFF input all outputs can be switched off (mode high ohmic), depending on the value of D0. STA A6 A5 A4 A3 A2 A1 A0 R/W AC D7 D6 D5 D4 D3 D2 D1 D0 AC STO STA = start condition A6 = 1 Fixed address bits A5 = 0 Fixed address bits A4 = 0 Fixed address bits A3 = 1 Fixed address bits A2 = sub-address bit, fixed via S2 input A1 = sub-address bit, fixed via S1 input A0 = sub-address bit, fixed via S0 input R/W = read/write bit (has to be 0, only write mode allowed) 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 |
