Abstract
A semiconductor device includes an external oscillation circuit connected to an external resonator, a self-exciting oscillation circuit, and an oscillation clock monitoring circuit, the oscillation clock monitoring circuit monitors an oscillation state of the external resonator using a clock signal generated by the self-exciting oscillation circuit, and when judged that the oscillation state has been stabilized, the terminating signal of the waiting time for stabilization of oscillation is outputted to terminate the waiting time for stabilization of oscillation of a microcomputer forcedly.
