Section 4. Interrupts
4.1 Contents
4.2 Introduction
The MCUs can be interrupted six different ways:
Non-maskable software interrupt instruction (SWI)
External asynchronous interrupt (IRQ)
Input capture interrupt (TIMER)
Output compare interrupt (TIMER)
Timer overflow interrupt (TIMER)
Port A interrupt (if selected via MOR2, bits 0–7)
Interrupts cause the processor to save the register contents on the stack
and to set the interrupt mask (I bit) to prevent additional interrupts. Unlike
reset, hardware interrupts do not cause the current instruction execution
to be halted, but are considered pending until the current instruction is
completed.
