如果處理器停止運(yùn)行，或者出現(xiàn)錯(cuò)誤，則必須使用重置環(huán)境丟失（向量表被破壞，堆棧損壞，等等）。? 冷復(fù)位和熱復(fù)位模式可用。? 默認(rèn)情況下，187Bug處于冷模式。
冷復(fù)位期間：1、進(jìn)行整個(gè)系統(tǒng)初始化，就像MVME187剛剛通電。
2、所有靜態(tài)變量（包括磁盤設(shè)備和控制器）參數(shù)）恢復(fù)到其默認(rèn)狀態(tài)。

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.
