一种使MCS-48系列单片微机实现多重中断嵌套的有效方法
A Method of Expanding Multi-level Interrupt Nesting to MCS-48 Family Single Chip Microcomputer
【摘要】 针对MCS-48系列单片微机仅具有单级中断结构的特点,本文提出一种用软件处理的方法,使单片机形成能实现多重中断嵌套的新的中断结构。从而扩展了单片机实时中断处理的功能。
【Abstract】 This article presents an effective method, by virture which a single-level interrupt source of single chip microcomputer can be expanded to more than ninelevel structure, so that the power of the chip in real-time interrupt processing might be enhanced to a great extent. Finally, some programs are offerd for reference.
