a. After V
CC
reaches 4.0 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.
3. Refer to figure 56.
4. Refer to figure 57.
5. Refer to figure 58.
6. Refer to figure 59.
7. Applies to the HD404334, HD404336, HD404338, HD4043312, and HD404339.
8. Applies to the HD4074339.
