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 masked through the enable bits), allowing an effective software management also in
absence of the possibility to serve the related interrupt request: a periodic polling of the flag
bits may be implemented inside the user application.
