Section 5 Interrupt Controller
5.6.2
In interrupt control mode 2, interrupt requests except for NMI and sleep interrupt are masked by
comparing the interrupt mask level (I2 to I0 bits) in EXR of the CPU and the IPR setting. There
are eight levels in mask control. Figure 5.4 shows a flowchart of the interrupt acceptance operation
in this case.
1. If an interrupt request occurs when the corresponding interrupt enable bit is set to 1, an
2. For multiple interrupt requests, the interrupt controller selects the interrupt request with the
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 contents are saved to the stack area during interrupt exception
6. The T bit in EXR is cleared to 0. The interrupt mask level is rewritten with the priority of the
7. The CPU generates a vector address for the accepted interrupt and starts execution of the

multiple interrupt requests have the same priority, an interrupt request is selected according to
