PURPOSE:To alter memory contents while a device is left in an operation state by transferring a table in the 1st memory space to the 2nd memory space and setting a flag, and controlling a program according to the flag. CONSTITUTION:When the memory contents are altered, a transfer program 6 is started by a start signal 7 to transfer the control table 1 from the memory space 2 to the memory space 3 successively and a discrimination flag 8 is set. When a judgement program 5 detects the setting of the flag 8, a program 4 refers to the table 1 in the memory space 3 and carries on the operation. The table 1 stored in the memory space 2 is altered into desired contents during said period. The flag 8 is reset on the alteration and when the judgement program detects that, the program 4 refers to the new table 1 in the memory space 2 and further carries on the processing. |
