Wakeup time from low-power mode
The wakeup times given in the following table are measured on a wakeup phase with the
MSI RC oscillator. The clock source used to wake up the device depends on the current
operating mode:
●
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 Deep sleep mode
●
Standby mode: the clock source is the MSI oscillator running at 2 MHz
All timings are derived from tests performed under ambient temperature and VDD supply
voltage conditions summarized in Table 9.
