NOTE:
Oscillation stabilization time (t
ST2
) is the time required for the oscillator to it’s normal oscillation when stop mode is
released by interrupts. The value Typ and Max are measured by buzzer output signal after stop release.
For example in voltage range of 4.5 V to 5.5 V of normal mode, we can see the buzzer output signal within 400 ms
at our test condition.
