Section 4. Interrupts
4.1 Contents
4.2 Introduction
The MCU can be interrupted five different ways:
Four maskable hardware interrupts, IRQ (interrupt request), SPI
(serial peripheral interface), SCI (serial communications
interface), and timer
Non-maskable software interrupt instruction (SWI)
Port B interrupts, if enabled, are combined with the IRQ to form a single
interrupt source.
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 (return to interrupt) instruction causes the register contents to be
recovered from the stack and normal processing to resume.
