  * @brief Tests some @ref RTEMSDeviceGRLIB directives.
  *
  * This test case performs the following actions:
  *
  * - Call grlib_load_8() to load a prepared value.
  *
  *   - Check that the returned value is equal to the prepared value.
  *
  * - Call grlib_load_16() to load a prepared value.
  *
  *   - Check that the returned value is equal to the prepared value.
  *
  * - Call grlib_load_32() to load a prepared value.
  *
  *   - Check that the returned value is equal to the prepared value.
  *
  * - Call grlib_load_64() to load a prepared value.
  *
  *   - Check that the returned value is equal to the prepared value.
  *
  * - Call grlib_store_8() to store a value to an object.
  *
  *   - Check that the value of the object is equal to the stored value.
  *
  * - Call grlib_store_16() to store a value to an object.
  *
  *   - Check that the value of the object is equal to the stored value.
  *
  * - Call grlib_store_32() to store a value to an object.
  *
  *   - Check that the value of the object is equal to the stored value.
  *
  * - Call grlib_store_64() to store a value to an object.
  *
  *   - Check that the value of the object is equal to the stored value.
  *
  * - Call apbuart_outbyte_polled() to store a character to the data register.
  *   The transmitter FIFO shall be initially non-empty.  The status is checked
  *   by apbuart_outbyte_wait().
  *
  *   - Check that the transmitter FIFO empty flag was set by ApbuartIORelax().
  *
  *   - Check that the data register was written by apbuart_outbyte_polled().
