该地址在加电和冷启动复位时加载到目标状态VBR中，并且可以通过使用RD命令在加电后立即显示目标状态寄存器来观察。4-14计算机组文献中心网站使用162Bug调试器4 162Bug使用表4-2中列出的调试器向量初始化目标向量表，并用通用异常处理程序的地址填充其他向量位置（请参阅本章中的162Bug通用异常处理器一节）。目标程序可以通过简单地将其自己的异常向量写入表来接管任意多的向量。如果表4-2中列出的矢量位置被覆盖，则伴随的调试器功能将丢失。162Bug维护一个单独的向量表供自己使用。通常，您不必知道调试器向量表的存在。它是完全透明的，您不应该对其中包含的向量进行任何修改。创建新向量表您的程序可能会在内存中创建一个单独的向量表，以包含其异常向量。如果这样做了，程序必须将VBR的值更改为指向新的矢量表。为了使用调试器工具，您可以将162Bug向量表中的正确向量复制到程序向量表中相应的向量位置。162Bug通用异常处理程序的向量（在本章的162Bug广义异常处理程序一节中详细描述）可以从目标向量表中的偏移$08（总线错误向量）复制到程序向量表中未使用单独异常处理程序时的所有位置。这在程序因意外异常而停止时提供诊断支持。通用异常处理程序提供目标寄存器的格式化显示，并标识异常的类型。保留调试器操作环境http://www.mcg.mot.com/literature4-15 4以下是一个例程的示例，该例程构建一个单独的向量表，然后将VBR移动到该表：***BUILDX-构建异常向量表***BUILUX MOVEC。
This address is loaded into the targetstate VBR at power up and cold-start reset and can be observed by using the RD command to display the target-state registers immediately after power up. 4-14 Computer Group Literature Center Web Site Using the 162Bug Debugger 4 The 162Bug initializes the target vector table with the debugger vectors listed in Table 4-2 and fills the other vector locations with the address of a generalized exception handler (refer to the 162Bug Generalized Exception Handler section in this chapter). The target program may take over as many vectors as desired by simply writing its own exception vectors into the table. If the vector locations listed in Table 4-2 are overwritten then the accompanying debugger functions are lost. The 162Bug maintains a separate vector table for its own use. In general, you do not have to be aware of the existence of the debugger vector table. It is completely transparent and you should never make any modifications to the vectors contained in it. Creating a New Vector Table Your program may create a separate vector table in memory to contain its exception vectors. If this is done, the program must change the value of the VBR to point at the new vector table. In order to use the debugger facilities you can copy the proper vectors from the 162Bug vector table into the corresponding vector locations in your program vector table. The vector for the 162Bug generalized exception handler (described in detail in the 162Bug Generalized Exception Handler section found in this chapter) may be copied from offset $08 (bus error vector) in the target vector table to all locations in your program vector table where a separate exception handler is not used. This provides diagnostic support in the event that your program is stopped by an unexpected exception. The generalized exception handler gives a formatted display of the target registers and identifies the type of the exception. Preserving the Debugger Operating Environment http://www.mcg.mot.com/literature 4-15 4 The following is an example of a routine which builds a separate vector table and then moves the VBR to point at it: * *** BUILDX - Build exception vector table **** * BUILDX MOVEC.
