PURPOSE: The method for rebooting is provided to report the processor down information to a user, and to display the down information of the system on the operator's terminal. CONSTITUTION: The interrupt intercept protection is configured to ignore the interrupt happened by the other device error(20). The system error table is fetched(22). The MPU(Micro-processor) checks if the content of the system error is a bus or an address error(24). If not a bus or an address error, the MPU fetches the user device error table(26). The related error content is processed(28). If yes at the step 24, the MPU runs the exception handling(30). The down flag, which is configured in the external RAM, is set(34). The information, such as the processor information state, the PC value, and the SR value, is saved on the down message area(36). The boot restarting is run according to the OS of the ROM(32).
