This file contains the example using XZDma driver to do simple data transfer in Normal mode on ZDMA device for 1MB data transfer.
MODIFICATION HISTORY:
Ver Who Date Changes
1.0 vns 2/27/15 First release vns 10/13/15 Declared static array rather than hard code memory. ms 04/05/17 Modified comment lines notation in functions to avoid unnecessary description to get displayed while generating doxygen. 1.3 mus 08/14/17 Do not perform cache operations if CCI is enabled 1.4 adk 11/02/17 Updated example to fix compilation errors for IAR compiler.
