PURPOSE:To complete timer service caused by one clock pulse within the period of clock pulse without fail, by dispersing and averaging the execution of timer service to integer-fold clock timer memories. CONSTITUTION:Every time a clock pulse is inputted from a signal line 1, a timer operation controlling circuit CC starts timer service. When the timer service to the basic clock timer memory started from a point of time t4 is finished, a selection circuit SEL is switched immediately, and addressing is made with a count value 1 of a timer number counter TM2, and timer service to the memory of the 1st address of integer-fold clock timer memories is made, and when this timer service is finished, a pulse is given on a signal line 4 and the count value 2 of the timer number counter TMN2 is obtained. The signal logic on a signal line 20 is high and the timer service to the memories on the 2nd address is performed succeedingly. When this is finished, a pulse is given on a signal line 4 and the count value of the TMN2 is 3. |
