2.10 Audio Interface
RTK79210XXB00000BE is equipped with a Cirrus audio CODEC WM8978 × 1 for audio interface. The WM8978
register control is performed on the channel 0 of the RZ/A2M on-chip Renesas serial peripheral interface (RSPI), and the
input/output control for audio data is performed on the channel 0 of the RZ/A2M on-chip serial sound interface (SSIF-2).
Figure 2.10.1 shows the audio interface block diagram, and Table 2.10.1 shows the function setting table of DIP
switches SW6-1 and SW6-2 for system setting.
