Use the interrupt priority level select bits to set their priority levels. Additionally, the reset, which is handled
as one that has the highest priority of all interrupts, and the watchdog timer interrupt have their priority levels
set by hardware. Figure 4.4.1 shows the interrupt priority levels set by hardware.
