Abstract

PURPOSE:To prevent a mulfunction of a control device very economically, by stopping a processor by a data protecting signal, in a control device of a data processing system which has been provided with a processor, a memory, etc. CONSTITUTION:When an electric power supply disconnection detecting circuit 8 which has detected an instantaneous disconnection of a circuit power supply 3 caused by an instantaneous disconnection of an input power supply 2 transfers a processor stop signal 12' to a processor 6, the processor 6 is stopped, following which a processor stop detecting circuit 10 and a resetting circuit 11 are operated in order, and a control device 5' is released automatically. Accordingly, a control device is released automatically by utilizing an existing function.
