技术手册上说 "use software interrupt to enter supervisor mode", 又给出了这样一张表格（这是其中一行）:
-----------------------------------------------------------------------------------------------------
Vector Offset Addr Exception Mode on entry I bit state of entry F bit on entry
8h Software interrupt Supervisor Set Unchanged
------------------------------------------------------------------------------------------------------
我大概知道使用汇编语言的SWI指令来产生软中断，但具体该如何写才能让处理器进入Supervisor模式呢？
谢谢解答！
