In applications where a 12 volt supply from slow blanking is used to derive the internal audio 9 Volt supply voltage, the VCCAO pin must be connected to the 12 volt supply as shown in the example. The VCCA pin will show the regulated 9 volt audio supply voltage which must be decoupled by capacitors.
In applications having a dedicated audio supply voltage, the VCCAO pin must be connected together with the VCCA pin to the audio supply as shown in the example. The VCCA pin acts as power supply input for the internal audio block.

IC bus selection
Data transfers follow the usual IC format; that is, after the start condition (S), a 7-bit slave address is sent, followed by an eight-bit data direction bit (W). An 8-bit sub-address is sent to select a register, followed by an 8-bit data word to be included in the register. The IC's IC bus decoder enables the automatic incrementation mode in write mode. The circuit operates at clock frequencies of up to 400 kHz. Table 14.
