-  * @brief      CRC Open

-  * @param[in]  u32Mode         CRC operation polynomial mode. Valid values are:
-  *                             - \ref CRC_CCITT

-  *                             - \ref CRC_32
-  * @param[in]  u32Attribute    CRC operation data attribute. Valid values are combined with:
-  *                             - \ref CRC_CHECKSUM_COM
-  *                             - \ref CRC_CHECKSUM_RVS
-  *                             - \ref CRC_WDATA_COM
-  *                             - \ref CRC_WDATA_RVS
-  * @param[in]  u32Seed         Seed value.
-  * @param[in]  u32DataLen      CPU Write Data Length. Valid values are:
-  *                             - \ref CRC_CPU_WDATA_8
-  *                             - \ref CRC_CPU_WDATA_16
-  *                             - \ref CRC_CPU_WDATA_32
-  *
-  * @return     None
-  *
-  * @details    This function will enable the CRC controller by specify CRC operation mode, attribute, initial seed and write data length. \n
-  *             After that, user can start to perform CRC calculate by calling CRC_WRITE_DATA macro or CRC_DAT register directly.
