5.6.1
In interrupt control mode 0, interrupts other than NMI are masked by ICR and the I bit of the CCR
in the CPU. Figure 5.5 shows a flowchart of the interrupt acceptance operation.
1. If an interrupt source occurs when the corresponding interrupt enable bit is set to 1, an
2. According to the interrupt control level specified in ICR, the interrupt controller accepts an
3. If the I bit in CCR is set to 1, only NMI and address break interrupt requests are accepted by
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 for NMI and address break
