Description of the EE note:

The application note explains in detail about the various schemes to interface 
High-Speed data converter AD7276 with ADSP-BF53x Blackfin Processor. The application 
note also provides example code to demonstrate how ADSP-BF53x Blackfin peripherals 
like SPI and Serial Ports can be programmed in order to receive data from AD7276 in 
core and DMA modes. Power-Down scheme for AD7276 between conversions is also described 
in the DMA mode of operation. The Interface has been tested on ADSP-BF535 EZ-KIT Lite.

The current directory contains "BF535 with AD7276" which has two sub folders containg
code. The sub-folders contained are :

1. SPI :  This folder has more folders that contain code for SPI. These various 
folders include code in DMA and core mode with different values of CPHASE.

2. SPORT : This folder contains two more folders which have code for serial port with 
Active HI Early frame sync and Active LOW LATE frame sync.
