Section 4. Interrupts
4.1 Contents
4.2 Introduction
The MCU can be interrupted four different ways:
Two maskable hardware interrupts, IRQ and timer
Non-maskable software interrupt instruction (SWI)
Optional external asynchronous interrupt on each port A pin
(enabled by pullup mask option)
Interrupts cause the processor to save register contents on the stack
and to set the interrupt mask (I bit) to prevent additional interrupts. The
return to interrupt (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.
