   2020-06-12       Hongjh          First version
   2020-07-23       Hongjh          1. Modify macro define for interrupt, flag and mode;
                                    2. Rename API: from DCU_IntFuncCmd to DCU_GlobalIntCmd;
                                    3. Refine API: DCU_IntCmd and delete DCU_SetCmpIntMode;
                                    4. Refine API: DCU DATA read/write.
   2020-09-07       Hongjh          Refine API: DCU_SetTriggerSrc
