Ver   Who     Date     Changes



1.0   vns     2/27/15  First release
      ms      04/05/17 Modified comment lines notation in functions to
                       avoid unnecessary description to get displayed
                       while generating doxygen and also changed filename
                       tag to include the file in doxygen examples.
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.
1.13    sk     08/02/21  Make Done variable as volatile to fix failure at
                         optimization level 2.
1.16  sa     09/29/22  Fix infinite loops in the example.
