Wake-up time from low-power modes

The times given in Table 37 are measured starting from the wake-up event trigger up to the

first instruction executed by the CPU:

•

for Stop or Sleep modes: the wake-up event is WFE.

•

WKUP (PA1) pin is used to wake-up from Standby, Stop and Sleep modes.

All timings are derived from tests performed under ambient temperature and VDD = 3.0 V.
