17.2.5 Interrupt priority logic
The interrupt priority block prioritizes the following requests:
• nonvectored interrupt requests
• vectored interrupt requests
• external interrupt requests.
The highest-priority request generates an IRQ interrupt if the interrupt is not currently
being serviced. Figure 17-6 shows a block diagram of the interrupt priority logic.
Note
nVICIRQIN is the daisy-chained IRQ request input.
