4.2 Introduction
The MCU can be interrupted six different ways:
1.
Non-maskable software interrupt instruction (SWI)
2.
External asynchronous interrupt (IRQ)
3.
Input capture interrupt (TIMER)
4.
Output compare interrupt (TIMER)
5.
Timer overflow interrupt (TIMER)
6.
Port A interrupt, if selected as a mask option
