Abstract
A basic clock signal generating circuit for use in a single chip microcomputer includes a frequency divider receiving an external clock signal for generating a frequency-divided clock signal, and a waveform shaping circuit receiving the frequency-divided clock signal output so as to generate a waveform-shaped frequency-divided clock as a basic clock of single chip microcomputer. An original oscillation clock generation circuit receives the external clock signal and generates an original oscillation clock having a frequency which is a-double of that of the basic clock. The basic clock and the original oscillation clock can be supplied to a peripheral circuit so that either the basic clock or the original oscillation clock can be selectively used in an internal circuit of the peripheral circuit.
