<p>PURPOSE:To automatically restore a fault generated in a program stored in a memory only by adding an external stand-by ROM at the occurance of the fault. CONSTITUTION:Specific data such as '00' are previously written in a specific address of the stand-by ROM 8, and at the time of detecting the specific address '00', an MPU 1 detects the loading of the ROM 8. Thereafter a control program in the ROM 8 is used to continue processing control operation.</p> |
