Abstract
In order to prevent the value of a flipflop from being indefinite during a period from a power-on time to the time a first clock signal is inputted, a reset circuit for a flipflop is configured to supply a clock to a clock input terminal of each of flipflops at the power-on time, so that an output of each flipflop never becomes indefinite. For example, in the case that an input/output of tristate buffers coinected in common to the same bus are controlled by a corresponding number of flipflops, respectively, a pass-through current caused for an output collision on the bus can be prevented with a relatively small scale of circuit.
