Abstract
PURPOSE: To make it possible to stop and reset a computer timing pulse without stopping a reference clock, by allowing a control circuit to expand and reset the timing pulse.
CONSTITUTION: To generate normal operation timing, a stop signal from control circuit 3 is OFF, timing generating circuit 2 is allowed to operate, and timing generating circuit 4 and control circuit 5 are both inhibited from operating, thereby generating timing pulses (b), (c), (d), and (e). Under the condition that timing pulses should be expanded in the prescribed period, control circuit 3 expands and resets timing pulses synchronizing with a reference clock. Consequently, it is possible to stop and reset computer timing pulses without stopping the reference clock.
