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:
●
●
●
All timings are derived from tests performed under ambient temperature and V
voltage conditions summarized in
Table 20.
1. Typical values are measured at T
2. Wakeup time until start of interrupt vector fetch.
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 MHz
