The DAI pins are connected to the AD1835A audio codec, the CS8414
SPDIF receiver, the audio oscillator output, and two push buttons.
Figure 3-3 illustrates the EZ-KIT Lite's connections to the DAI.

Refer to "Using Analog Audio" on page 2-3
page 2-5 for more information about setting up the DSP to communicate
with these devices.
To use the DAI for a different purpose, disable any signal, which is driv-
ing the DAI pins, with a switch. See
page 3-9 and "SPDIF Signal Enable Switch (SW8)" on page 3-10
to. In addition, the codec setup switch allows flexible routing of the
12.288 MHz audio oscillator's output signal. By default, this signal is
used as the master clock (
