Abstract

PURPOSE:To facilitate the production and control of a program of a main device, by giving the priority to the timer operating indication given from the main device in case both the timer operating indication and a timer interruption given from a multi-timer device are produced at a time. CONSTITUTION:The timer operating indication information given from a main device MC is supplied to a timer operating indication register RQR through a signal line 101. At the same time, the timer operating indication FFRQI is turned significant through a signal line 102, and an output signal line 119 of a timer interruption holding FF-MSK is set insignificant. Under such conditions, an output signal 113 of a timer interruption FF-EDI is not delivered to a signal line 120 through an AND gate ADI and is not conveyed to the device MC. At the same time, the timer operating indication is detected through a timer arithmetic circuit CC, and at the same time the timer part of a register RQR is compared with the value of the register through an indication coincidence circuit CPR. When a coincidence is detected, the circuit CC resets the FF-EDI with the output of a signal line 121 to discontinue the timer interruption to the device MC.
