15.6 Securing Oscillation Stabilization Time
oscillation stabilization time is the reset value of the OSTS register, 2
is released by reset signal (RESET pin input, reset signal generation by low-voltage detection (LVIRES), and reset
signal generation by power-on clear (POCRES)).
the other half is the stabilization time of the PLL. Set an oscillation stabilization time double that of the oscillation
stabilization time of the oscillator used when the STOP mode is released.
time of the watchdog timer.
Oscillated waveform
STOP mode status
When the STOP mode is released, the oscillation stabilization time set by the OSTS register elapses. The
However, the actual oscillation stabilization time is half this value (after reset: 2
The timer for counting the oscillation stabilization time secures oscillation stabilization time equal to the overflow
The operation performed when the STOP mode is released by an interrupt request signal is shown below.
