available vector. If more than one source is enabled to issue the request, the service routine
will have to take care to identify the real event to be serviced. This can easily be done by
checking the flag bits (byte low of XIRxSEL register). Note that the flag bits can also provide
information about events which are not currently serviced by the interrupt controller (since
they are masked through the enable bits), allowing an effective software management even
if the related interrupt request cannot be served: A periodic polling of the flag bits may be
implemented inside the user application.
