Semiconductor integrated circuit having a plurality of oscillation circuits |
摘要 |
Operation of a clock generating circuit is stopped when the oscillation signals to be selectively transmitted to the clock generating circuit via a multiplexer are switched. The oscillation signals are generated by a first oscillation circuit at a relatively high frequency and by a second oscillation circuit which steadily oscillates at a relatively low frequency. The clock generating operation is resumed in synchronization with the switched oscillation signals.
