I am doing following steps for clearing Rx interrupt

   

 

   

1. Attach the interrupt component to the pin on the SCB in the schematic

   

2. Create an ISR in your code by using the CY_ISR() macro

   

3. Start the ISR by running the interrupt_StartEx()

   

4. In the ISR you need to clear the interrupt source.. .this point i dont know which function is doing this

   

please help me to resolve this.

Reading the data from your interface as long as the fifo is not empty will clear the interrupt source. For instance:

   

SCB_UartGetChar() or SCB_UartGetByte()
