Section 6 Interrupt Controller (INTC)
6.6
6.6.1
The sequence of interrupt operations is described below. Figure 6.2 shows the operation flow.
1. The interrupt request sources send interrupt request signals to the interrupt controller.
2. The interrupt controller selects the highest-priority interrupt from the interrupt requests sent,
3. The priority level of the interrupt selected by the interrupt controller is compared with the
4. When the interrupt controller accepts an interrupt, a low level is output from the IRQOUT pin.
5. The CPU detects the interrupt request sent from the interrupt controller when the CPU decodes
6. The interrupt exception service routine start address is fetched from the exception handling
7. The status register (SR) is saved onto the stack, and the priority level of the accepted interrupt
8. The program counter (PC) is saved onto the stack.
9. The CPU jumps to the fetched interrupt exception service routine start address and starts
10. A high level is output from the IRQOUT pin. However, if the interrupt controller accepts an

following the priority levels set in interrupt priority registers 01, 02, and 05 to 17 (IPR01,
IPR02, and IPR05 to IPR17). Lower priority interrupts are ignored*. If two of these interrupts
have the same priority level or if multiple interrupts occur within a single IPR, the interrupt
with the highest priority is selected, according to the default priority and IPR setting unit
internal priority shown in table 6.4.
interrupt level mask bits (I3 to I0) in the status register (SR) of the CPU. If the interrupt
request priority level is equal to or less than the level set in bits I3 to I0, the interrupt request is
ignored. If the interrupt request priority level is higher than the level in bits I3 to I0, the
interrupt controller accepts the interrupt and sends an interrupt request signal to the CPU.
