ADSP-21262 EZ-KIT Lite Evaluation System Manual
3-5
EZ-KIT Lite Hardware Reference
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
and
“Using Digital Audio” on
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
“Codec Setup Switch (SW7)” on
page 3-9
and
“SPDIF Signal Enable Switch (SW8)” on page 3-10
for how
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 (
MCLK
) for the AD1835A codec.
