Wakeup time from low-power mode
The wakeup times given in Tabl e 26 are measured on a wakeup phase with an 8-MHz HSI
RC oscillator. The clock source used to wake up the device depends from the current
operating mode:
● Stop or Standby mode: the clock source is the RC oscillator
● Sleep mode: the clock source is the clock that was set before entering Sleep mode.
All timings are derived from tests performed under the ambient temperature and V
