Hi @Sathiya_T

Please refer to usart_transfer_ring_buffer example readme.

***Note:*** Board will not immediately return each character to terminal emulator until
all 8 characters are all entered.

It waited for all 8 of his inputs to be completed before entering the interrupt.

Hope this will help you.
