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:

● 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

All timings are derived from tests performed under ambient temperature and VDD supply

voltage conditions summarized in Table 14.
