-  Performs an atomic compare exchange operation on the 32-bit unsigned integer

-  ExchangeValue and CompareValue is returned.  If Value is not equal to CompareValue,
-  then Value is returned.  The compare exchange operation must be performed using

-  @param  CompareValue  32-bit value used in compare operation.
-  @param  ExchangeValue 32-bit value used in exchange operation.
