4.向量区的保护
在186机中，从。~377号单元为系统向量区，在这里存放的信息极为重要，不允许破坏，由于系统堆栈通常设置在系统向量区之上，而且它是向低地址扩展的，所以进栈操作有可能破坏向量区。为防止进栈操作破坏系匆句量区，在186机内，设有堆栈溢出检测功能，当进栈地址小于(400)8时引起“堆栈溢出”内中断。
5.中断系统
介绍了中央处理机内程序可访的主要资源的基础上，以中断系统为题目来说明系统各部分相互作用的约定。
(1)直传请求和直传
在186机中，直传请求只是请求单总线控制权，在获得总线控制权后，总线上的丙个设备之间直接传送数据，无需中央处理机为干预。但因为在单总线使用上会与中央处理礼发生冲突，所以规定两者的优先次序。在180系列中，直传请求的优先级高于处理机。在186机中更是重点保证直传请求能获得快的响应。基本上做到现行总线周期一结束就予以响应。所以直传请求的等待时间不大于代个存贮周期。直传请求设备一旦获得控制权以后，可按与之协同工作的存贮器等效周期时间相同的速度进行高速传输。
(2)外设硬件中断请求
186计算机设置了四根外中断请求线，供单总线上的外设为中断的目的请求总线控制权。外中断请求在中央处理机完成一条指令时，按预定的硬件优先级予以响应，在所有请求中优先级高的设备取得总线控制权。通过外中断请求线取得总线控制权的设备原则上可以进行两种可能的操作：(l)启动总线数据传输(2)发中断命令及中断向量地址，使处理机执行它所要求的中断服务程序。或者在进行种操作之后再进行第二次操作。实际上在180系列中的大多数设备通过外中断请求获得控制权的设备只进行第二种操作。
(3)内中断和紧急内中断
中央处理机和存贮系统发生的错误和某些指令的执行，使处理机中断现行程序转而执行相应的中断处理程序。这个过程与响应外中断请求的过程相类似，由于中断源是在中央处理机内部，所以称为内中断。根据内中断源的性质，内甲断分为内中断和紧急内中断两类。凡是检测到一次内中断请求时，本条指令尚能执行完毕，然后再转入中断处理的称为一般内中断;凡是内中断的原因使本条指令不能进行下去，中止引起内中断的操作，立即转人中断处理的，称为紧急内中断。
(4)中断的申请及优先级结构
内中断及紧急内中断源直接向处理机申请中断并提供中断向量地址。内中断不受处理机优先级的屏蔽，即可视为优先于所有处理机程序。外部设备请求中断表现为请求总线控制权的形式。对总线控制权处理取决于设备在单总线优先级结构中的位置。
