Figure 16. Adding an ADAU1777
To use the USB interface to communicate with the target
integrated circuit (IC), connect it by clicking and dragging a
wire between the blue pin of the USBi and the green pin of the
IC (see Figure 17). The corresponding drop-down box of the
USBi automatically fills with the default mode and channel for
that IC.
