Notes: 1. There are three cases where the oscillator stabilization period applies:
When power is first applied, the time between the point when V
CC reaches min and
the point the oscillator is stable.
When stop mode is cleared, the time between the point when the
RESET input
reaches the low level and the point the oscillator is stable.
When stop mode is cleared, the time between the point when the
STOPC input
reaches the low level and the point the oscillator is stable.
To assure the time necessary to achieve stable oscillation at power on and when
clearing stop mode, apply a low level to the
RESET or STOPC input for at least t
RC.
Since the oscillator stabilization period varies with the details of the mounted circuit,
stray capacitances, and other factors, this value should be determined based on
thorough consultations with the manufacturer of the ceramic oscillator used.
