There are no active I2S1 devices on the Evaluation Carrier (the switch is a high speed analog switch, technically not an
I2S device). The switch is controlled via an I2C expander described in the I2C section above. The hardware defaults to
option 1) above on power up; no special I2C set up is needed for that option.

» I2S2 port goes to / from the Evaluation Carrier I/O Mezzanine.
» Loop back for system test.
