5.6.1
In interrupt control mode 0, interrupt requests other than NMI and address break are masked by
ICR and the I bit of the CCR in the CPU. The interrupt requests are held pending when the I bit is
set to 1. Figure 5.4 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 only accepts
3. If the I bit in CCR is set to 1, only NMI and address break interrupts are accepted by the
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
7. The CPU generates a vector address for the accepted interrupt and starts execution of the
