Interrupt Priority
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 with the highest
priority is serviced first. If requests of the same priority are received simultaneously, 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 as shown in
The interrupt priority is configured in the corresponding NVIC control register:
