Hi Vladimir,
The FIFO size is not relevant here. You must only ensure, that you can read the FIFO as fast as the Reader fill it. If the interrupt request for a non-empty FIFO occurs, you must read and save the data unless the FIFO is empty.
If the FIFO size is small, the response time must be short. On larger FIFOs you can accept larger response times.
