摘要： An oscillation stabilization detecting circuit comprises a T flip flop receiving a pulse-type oscillation signal generated by oscillating a crystal oscillator and then dividing the oscillation signal to output; a pulse control unit including inverters and transistors, the pulse control unit converting the signal output from the T flip flop into a pulse-type signal starting from a high level and then outputting the converted signal; and an oscillation stabilization detecting unit including a capacitor charged with the signal output from the pulse control unit; and a plurality of transistors. The oscillation stabilization detecting unit controls charging time of the capacitor by adjusting a bias current and, after the charging time passes, outputs a stabilization signal to a CPU, the stabilization signal representing that the oscillation signal is stabilized.
