Wakeup time from low-power mode

The wakeup times given in Table 34 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 VDD supply

voltage conditions summarized in Table 19.
