If two or more interrupt requests are existed at the same sampling points (a timing to detect whether an
interrupt request is generated or not), the interrupt with the highest priority is acknowledged.
Set the ILVL2 to ILVL0 bits to select the desired priority level for maskable interrupts (peripheral function
interrupt).
Priority levels of special interrupts such as reset (reset has the highest priority) and watchdog timer are
set by hardware. Figure 11.8 shows priority levels of hardware interrupts.
The interrupt priority does not affect software interrupts. Executing instruction causes the microcomputer
to execute an interrupt routine.

The interrupt priority level select circuit selects the highest priority interrupt when two or more interrupt
requests are existed at the same sampling point.
Figure 11.9 shows the interrupt priority level select circuit.
