Abstract

PURPOSE: To eliminate the need of the modification of a program by composing a timer for clocking unit generation and a main timer for interruption signal generation and by generating a signal of a constant period such as interruption signal at the time of a change in basic pulse of a clock circuit.
CONSTITUTION: A basic pulse from clock circuit 10 is supplied to sub timer 12 via signal line 11 and the output of timer 12 is to AND circuit 14 via jumper method 13. When outputs of signal lines 500 to 507 are all "1", lacing preventive FF16 is energized to reset all bits of timer 12 and pulses of various counting units are generated through the selection of jumper method 13. Further, the output of FF16 is applied to main timer 20 and its output signal lines 600 to 607 are connected to signal lines 700 to 707 through the selection of jumper method 21, thereby controlling lacing preventive FF25. The output of this timer 20 is connected to read gate 27 and indication signal line 28 indicating interval timer read operation is energized to generate an interruption signal of a constant period.
