6.3.6 Wakeup time from low-power mode
The wakeup times given in Table 37 are measured from the wakeup event trigger to the first
instruction executed by the CPU. The clock source used to wake up the device depends
from the current operating mode:
• Stop or sleep mode: the wakeup event is WFE.
• The WKUP1 (PA0) pin is used to wakeup from standby, stop and sleep modes.

1. When peripherals are enabled, power consumption of the analog part of peripherals such as ADC, DACs,
Comparators, etc. is not included. Refer to those peripherals characteristics in the subsequent sections.
2. The BusMatrix is automatically active when at least one master is ON (CPU, DMA1 or DMA2).
3. The APBx Bridge is automatically active when at least one peripheral is ON on the same Bus.
