Abstract
A semiconductor integrated circuit of this invention includes an oscillation circuit formed on a semiconductor substrate, a frequency dividing circuit formed on the semiconductor substrate, for dividing a frequency of an oscillation output from the oscillation circuit, clocked inverters for selectively permitting one of an original oscillation frequency signal of the oscillation circuit and outputs of the frequency dividing circuit to pass therethrough, an output circuit for outputting a signal selected by the cocked inverters, and a frequency dividing circuit controlling NAND circuit for interrupting the operation of the frequency dividing circuit while the original oscillation frequency signal of the oscillation circuit is being output from the output circuit.
