Notes: 1. The oscillation stabilization time is the period required for the oscillator to stabilize in the
following situations:
a.
After V
CC
reaches 2.7 V 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 crystal or 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 77.
3. Refer to figure 78.
4. Refer to figure 79.
5. Refer to figure 80.
