Electrical characteristics

6.3.9

Wakeup time from Low-power modes and voltage scaling

transition times

The wakeup times given in Table 51 are the latency between the event and the execution of

the first user instruction.

The device goes in Low-power mode after the WFE (Wait For Event) instruction.
