intruction's exectuion, and interrupt can happen in between instructions。
这里我不太清楚after an intruction's exectuion 和between instructions的差别。
难道是指的exceptions 是一个在取指令周期，取数据周期和执行周期都完成之后发生
，而interrupt 可以在这些周期之间发生？
请教高手，谢谢！ | j**********p

instructions, while interrupts are irrelevant to instructions, which could
be after or in between instructions.

hardware devices. Exception is generated by CPU (instructions) after the
termination of instruction (typically). |
