4.2 Introduction
The MCU can be interrupted by five different sources, four maskable
hardware interrupts, and one non-maskable software interrupt:
External signal on the IRQ pin or port B pins
16-bit programmable timer
Serial communications interface
Serial peripheral interface
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.
Unlike RESET, hardware interrupts do not cause the current instruction
execution to be halted, but are considered pending until the current
instruction is complete.
NOTE:
The current instruction is the one already fetched and being operated on.
