3.4.3
An interrupt that is currently being serviced can only be interrupted by a higher-priority
interrupt, but not by another interrupt of the same or lower priority. Hence, an interrupt of
the highest priority cannot be interrupted by any other interrupt request.
If two or more requests of different priority levels are received simultaneously, the
request of the highest priority is serviced first. If requests of the same priority are
received simultaneously, then an internal polling sequence determines which request is
serviced first. Thus, within each priority level, there is a second priority structure
determined by the polling sequence shown in
