Section 5 Interrupt Controller
5.6.1
In interrupt control mode 0, interrupt requests except for NMI is masked by the I bit of CCR in the
CPU. Figure 5.3 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
2. If the I bit is set to 1, only an NMI interrupt is accepted, and other interrupt requests are held
3. Interrupt requests are sent to the interrupt controller, the highest-ranked interrupt according to
4. When the CPU accepts an interrupt request, it starts interrupt exception handling after
5. The PC and CCR are saved to the stack area by interrupt exception handling. The PC saved on
6. Next, the I bit in CCR is set to 1. This masks all interrupts except NMI.
7. The CPU generates a vector address for the accepted interrupt and starts execution of the
