Abstract

PURPOSE:To simplify the interrupting and restarting processing in accordance with the interruption, by receiving a report signal from an input and output device at a central controller and starting an input and output interruption processing function at a start period of a periodic interruption processing function. CONSTITUTION:At a central controller 1 of an electronic exchanger, when a clock signal (a) with a prescribed period is transmitted from a clock generating circuit 2, an FF3 is set, an interrupting section 6 is started, a processing C during the execution at present is intrerrupted, a periodic interruption processing section 7 is started and a processing A such as a dial pulse reception and detection is executed. When the execution of the processing A is finished, the program is returned to the processing C for the execution. If operation completion report signals b1 and b2 from an input and output device 4 are inputted to the device 1, the step is waited until the next periodic signal (a) is generated at an AND gate 9. The processing C is interrupted when the signal (a) is generated, the processing A is executed, a gate 9 is opened, an FF5 is set and a signal (b) is inputted to the interruption section 6. When the execution of the processing A is finished, an input and output interrupting processing section 8 is started and processings B1 and B2 corresponding to the signals b1 and b2 are executed.
