IRQ interrupt handling experimental results of this experiment, the system is running, press any key 12345678, the corresponding Ba Duan digital tube will light up. Debug in flash, you need to modify the RO BASE is 0x00000000, the other not modify, recompile download can run. Note: Due to system interrupt, the program counter will jump to 0x18 Department execute the interrupt service routine, it can not debug the SDRAM.
