According to the hardware sch, the Bluetooth module is connected to the port4 of AUDMUX and the Codec is connected to the port 3 of AUDMUX, the both ports using I2S interface. I have two puzzled as the following shows:
1. If the two ports configed as I2S means I have to connect two SSI to the AUDMUX and set them as I2S mode? Shall I have to add one SSIn connect to the port 4 as the following red line?
2. As the manual, the 2 external port (port 3 & 4) can be connected together in the normal mode. If I just add the link between port 3 & 4?
