The AD535 module (audio codec supported by the C6711 DSK) serves as a
level of abstraction such that it works the same for all AD535s supported on
TI EVM/DSKs.

To use an AD535 device, you must first open it and obtain a device handle us-
ing 

AD535_open()

. Once opened, use the device handle to call the other API

functions. The codec may be configured by passing an 

AD535_Config

 struc-

ture to 

AD535_config()

.
