周工您好: smart2200,初始化部份,有一LPC2294文件中,最后定义的固件函数,怎样去理解,它们有什么样作用。 #define rm_init_entry() ((void (*)())(0x7fffff91))() #define rm_undef_handler() ((void (*)())(0x7fffffa0))() #define rm_prefetchabort_handler() ((void (*)())(0x7fffffb0))() #define rm_dataabort_handler() ((void (*)())(0x7fffffc0))() #define rm_irqhandler() ((void (*)())(0x7fffffd0))() #define rm_irqhandler2() ((void (*)())(0x7fffffe0))() #define iap_entry(a, b) ((void (*)())(0x7ffffff1))(a, b) |
