按下并释放MVME187前面板重置开关启动系统重置。
如果处理器停止运行，或者出现错误，则必须使用重置环境丢失（向量表被破坏，堆栈损坏，等等）。❏ 冷复位和热复位模式可用。❏ 默认情况下，187Bug处于冷模式。
冷复位期间：1、进行整个系统初始化，就像MVME187刚刚通电。
2、所有静态变量（包括磁盘设备和控制器）参数）恢复到其默认状态。

5.清除输入和输出字符队列。6、车载设备（计时器、串行端口等）重置，以及
7.将前两个串行端口重新配置为其默认值状态在热复位期间：1.187Bug变量和表被保留，以及目标状态寄存器和断点。
中止通过按下并释放上的Abort开关来调用AbortMVME187前面板。
如果程序被捕获，则应使用中止来重新获得控制在循环中等。每当在运行目标代码时调用abort时（用户程序），捕捉处理器状态的“快照”，并存储在目标寄存器中。因此，中止是最重要的在终止正在运行的用户程序时适用已调试。目标IP、注册内容等有助于精确定位故障中止序列按下并释放中止开关可执行以下操作：1、生成一个本地板条件，该条件可能会中断处理器（如果启用）。2、在屏幕上显示目标寄存器，反映按下中止开关时的机器状态。
3.删除用户代码中安装的任何断点，并保持断点表不变。
4.将控制返回给调试器。
Pressing and releasing the MVME187 front panel RESET switch
initiates a system reset.
Reset must be used if the processor ever halts, or if the 187Bug
environment is ever lost (vector table is destroyed, stack corrupted,
etc.).
❏ COLD and WARM reset modes are available.
❏ By default, 187Bug is in COLD mode.
During COLD reset:
1. A total system initialization takes place, as if the MVME187
had just been powered up.
2. All static variables (including disk device and controller
parameters) are restored to their default states.
3. The breakpoint table and offset registers are cleared.
4. The target registers are invalidated.
5. Input and output character queues are cleared.
6. Onboard devices (timer, serial ports, etc.) are reset, and
7. The first two serial ports are reconfigured to their default
state.
During WARM reset:
1. The 187Bug variables and tables are preserved, as well as the
target state registers and breakpoints.
Abort
Abort is invoked by pressing and releasing the ABORT switch on the
MVME187 front panel.
Abort should be used to regain control if the program gets caught
in a loop, etc. Whenever abort is invoked while running target code (a user
program), a “snapshot” of the processor state is captured and
stored in the target registers. For this reason, abort is most
appropriate when terminating a user program that is being
debugged. The target IP, register contents, etc., help to pinpoint the
malfunction.
Abort Sequence
Pressing and releasing the ABORT switch does the following:
1. Generates a local board condition which may interrupt the
processor if enabled.
2. Displays the target registers on the screen, reflecting the
machine state at the time the ABORT switch was pressed.
3. Removes any breakpoints installed in the user code and
keeps the breakpoint table intact.
4. Returns control to the debugger.
