power-on or after RESET input goes high after stop mode is canceled. At power-on and when
stop mode is cancelled, RESET must be input for at least t
stabilization time. If using a crystal oscillator or a ceramic oscillator, contact its manufacturer to
determine what stabilization time is required, since it will depend on the circuit constants and
stray capacitances.
