6.3.6 Wakeup time from low-power mode
The wakeup times given in Table 37 are measured starting from the wakeup event trigger up
to the first instruction executed by the CPU:
 For Stop or Sleep mode: the wakeup event is WFE.
 WKUP1 (PA0) pin is used to wakeup from Standby, Stop and Sleep modes.
All timings are derived from tests performed under ambient temperature and V
