<p>PURPOSE: To continue a stable operation by preventing it that a peripheral circuit is reset due to a noise signal or the like intruded on a reset signal line. CONSTITUTION: In the CPU application system including a CPU 1 and a CPU peripheral circuit 3, and in the CPU application circuit where the CPU 1 and the CPU peripheral circuit 3 are reset by a reset signal from a reset circuit 2 generating the reset signal, the supply of the reset signal to the CPU peripheral circuit 3 is conducted by providing a reset time control circuit 5 which generates a reset signal for the peripheral circuit continuously over a time required at least for the CPU 1 to be transited to the reset operation and provides the reset signal to the CPU peripheral circuit 3.</p> |
