enIntSrc Interrupt number 
enIRQn  Interrupt priority 
pfnCallback  Callback function

The next step is to register a

    /* Register error IRQ handler && configure NVIC. */
    stcIrqSigninCfg.enIRQn = USART_UNIT_ERR_INT_IRQn;// Interrupt priority 
    stcIrqSigninCfg.enIntSrc = USART_UNIT_ERR_INT_SRC;// Interrupt number 
    stcIrqSigninCfg.pfnCallback = &USART_RxErr_IrqCallback;
    InstalIrqHandler(&stcIrqSigninCfg, DDL_IRQ_PRIORITY_DEFAULT);
