The MCU can be interrupted seven different ways:
1. Nonmaskable software interrupt instruction (SWI)
2. External asynchronous interrupt (IRQ)
3. External interrupt via IRQ on PC0–PC7
4. Internal 16-bit timer interrupt (TIMER)
5. Internal synchronous serial interface (SSI) interrupt
6. Internal core timer interrupt
7. Comparator 3
