程序必须确保堆栈中存在异常堆栈帧。在跳转到异常处理程序的地址之前，它必须与处理器为特定异常创建的完全相同。下面是一个异常处理程序示例，它可以将异常传递给调试器：B&R 4P3040.01-490通用异常处理程序B&R 4P3040.01-490有一个通用异常处理器，它使用它来处理表中未列出的所有异常4-2.对于所有这些异常，目标堆栈指针都指向创建的异常堆栈帧的顶部。这样，如果在代码执行过程中发生意外异常，将向您提供异常堆栈框架，以帮助确定异常的原因。以下示例对此进行了说明：示例：地址$F00000处的总线错误。对于本示例，假设对存储器位置$F00000的访问启动了总线错误异常处理。B&R 4P3040.01-490
Your program must make sure that there is an exception stack frame in the stack. It must be exactly the same as the processor would have created for the particular exception before jumping to the address of the exception handler.The following is an example of an exception handler which can pass an exception along to the debugger:162Bug Generalized Exception Handler The B&R 4P3040.01-490 has a generalized exception handler which it uses to handle all of the exceptions not listed in Table 4-2. For all these exceptions, the target stack pointer is left pointing to the top of the exception stack frame created. In this way, if an unexpected exception occurs during execution of your code, you are presented with the exception stack frame to help determine the cause of the exception. The following example illustrates this: Example: Bus error at address $F00000. It is assumed for this example that an access of memory location $F00000 initiates bus error exception processing.B&R 4P3040.01-490
