The oscillator stabilization time is period from when Voc reaches its minimum allowable voltage at power-on until when the oscillator stabilizes, or after RESET goes high. At power-on or recovering from stop mode, apply the RESET input for more than tag to meet the necessary time for oscillator stabilization. When using a crystal or ceramic oscillator, consult with the crystal and ceramic oscillator manufacture since the oscillator stabilization time depends on the circuit con- stant and stray capacitance. 2.
