Section 4. Interrupts
4.1 Contents
4.2 Introduction
The MCU can be interrupted by:
1. Non-maskable Software Interrupt Instruction (SWI)
2. External Asynchronous Interrupt (IRQ)
3. Optional External Asynchronous Interrupt on Each Port A Pin
(IRQ, Enabled by Pullup Mask Option)
4. Input Capture Interrupt (TIMER)
5. Output Compare Interrupt (TIMER)
6. Timer Overflow Interrupt (TIMER)
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.
