Section 4. Interrupts
4.1 Contents
4.2 Introduction
The MCU can be interrupted six different ways: the five maskable
hardware interrupts (IRQ, timer, CPI, SSI, and M bus) and the
nonmaskable software interrupt instruction (SWI).
Interrupts cause the processor to save register contents on the stack
and to set the interrupt mask (I bit) to prevent additional interrupts. The
RTI instruction causes the register contents to be recovered from the
stack and normal processing to resume.
