Notes: 1. The oscillation stabilization time is the period required for the oscillator to stabilize in the
following situations:
a.
After V
CC
reaches the minimum specification value at power-on.
b.
After
RESET
input goes low when stop mode is cancelled.
c.
After
STOPC
input goes low when stop mode is cancelled.
To ensure the oscillation stabilization time at power-on or when stop mode is cancelled,
RESET
or
STOPC
must be input for at least a duration of t
RC
.
When using a ceramic oscillator, consult with the manufacturer to determine what stabilization
time is required, since it will depend on the circuit constants and stray capacitance.
2. Refer to figure 66.
3. Refer to figure 67.
4. Refer to figure 68.
5. Refer to figure 69.
