  * Description:
  *     This function that implements the MarchC Minus test.
  *     This test is a destructive test !!!
  * Input:
  *     data[]  :  pointer to an array declared in user memory
  *     MAX_MEM :  value indicating the number of bytes to test
  * Return Values:
  *     FAIL :  return value = 0
  *     PASS :  return value = 1
  *
