Section 5 Interrupt Controller
5.5.2
Enabling and disabling of IRQ interrupts, WKP interrupts and on-chip peripheral module
interrupts can be set by means of the I bit in the CPU’s CCR. Interrupts are enabled when the I bit
is cleared to 0, and disabled when set to 1.
Figure 5.9 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
