5.5.2
The interrupt priority order is predetermined. When multiple interrupts occur simultaneously
(overlap), the interrupt controller (INTC) determines their relative priorities and starts processing
according to the results.
The priority order of interrupts is expressed as priority levels 0 to 16, with priority 0 the lowest
and priority 16 the highest. The NMI interrupt has priority 16 and cannot be masked, so it is
always accepted. The user break interrupt and H-UDI interrupt priority level is 15. Priority levels
of IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts can be set freely
using the interrupt priority registers 01, 02, and 05 to 17 (IPR01, IPR02, and IPR05 to IPR17) of
the INTC as shown in table 5.9. The priority levels that can be set are 0 to 15. Level 16 cannot be
set. See section 6.3.1, Interrupt Priority Registers 01, 02, 05 to 17 (IPR01, IPR02, IPR05 to
IPR17), for details of IPR01, IPR02, and IPR05 to IPR17.
