然后定义一个连续的数据段,并把中断处理函数的入口地址值赋给各字单元
ExceptionHandlerTable
DCD UserCodeArea
DCD SystemUndefinedHandler
DCD SystemSwiHandler
DCD SystemPrefetchHandler
DCD SystemAbortHandler
DCD SystemReserv
DCD SystemIrqHandler
DCD SystemFiqHandler
其中的DCD SystemSwiHandler 是为MAP和#定义的结构化内存表中的数据域分配内存并用SystemSwiHandler标号初始化吗?
