5.5 Interrupt Priority
Chapter 5
Figure 5.5.1. Interrupt priority that is set in hardware
If two or more interrupt requests are sampled active at the same time, whichever interrupt request is ac-
knowledged that has the highest priority.
Maskable interrupts (Peripheral I/O interrupts) can be assigned any desired priority by setting the interrupt
priority level select bit accordingly. If some maskable interrupts are assigned the same priority level, the
priority between these interrupts is resolved by the priority that is set in hardware
Certain nonmaskable interrupts such as a reset (reset is given the highest priority) and watchdog timer
interrupt have their priority levels set in hardware. Figure 5.5.1 lists the hardware priority levels of these
interrupts.
Software interrupts are not subjected to interrupt priority. They always cause control to branch to an inter-
rupt routine whenever the relevant instruction is executed.
*1 Hardware priority varies with each M16C model. Please refer to your M16C User’s Manual.
