Device for detecting a plurality of signal levels indicating stopping of a clock signal |
摘要 |
The oscillation-stop detecting device accurately detects the stopping of a clock signal due to various causes. The voltage detecting circuit detects when a clock signal output from the clock signal oscillator remains at a high, a low or an intermediate level, and outputs a clock voltage detection signal. The oscillation-stop detecting circuit outputs a detection signal in response to the voltage detection signal.
