Section 5 Interrupt Controller
5.5.3
Eight-level masking is implemented for IRQ interrupts, WKP interrupts and on-chip peripheral
module interrupts by comparing the interrupt mask level set by bits I2 to I0 of EXR in the CPU
with IPR.
Figure 5.10 shows a flowchart of the interrupt acceptance operation in this case.
1. If an interrupt source occurs when the corresponding interrupt enable bit is set to 1, an interrupt
2. When interrupt requests are sent to the interrupt controller, the interrupt with the highest
3. Next, the priority of the selected interrupt request is compared with the interrupt mask level set
4. When the CPU accepts an interrupt request, it starts interrupt exception handling after
5. The PC, CCR, and EXR are saved to the stack area by interrupt exception handling. The PC
6. The T bit in EXR is cleared to 0. The interrupt mask level is rewritten with the priority level of

priority according to the interrupt priority levels set in IPR is selected, and lower-priority
interrupt requests are held pending. If a number of interrupt requests with the same priority are
generated at the same time, the interrupt request with the highest priority according to the
priority system shown in table 5.2 is selected.
