Wakeup time from low-power mode
The wakeup times given in the following table are measured with the MSI RC oscillator. The
clock source used to wake up the device depends on the current operating mode:
●
●
●
All timings are derived from tests performed under ambient temperature and V
voltage conditions summarized in
Table 22.
1. Based on characterization, not tested in production, unless otherwise specified
Sleep mode: the clock source is the clock that was set before entering Sleep mode
Stop mode: the clock source is the MSI oscillator in the range configured before
entering Stop mode
Standby mode: the clock source is the MSI oscillator running at 2.1 MHz
