Hi tech community team,

I'd like to know the spec of wake-up pins regarding fall time and rise time.

I checked datasheet however I couldn't  find them.

The wake-up pins are four pins, wakeup0/1/2/3. 

best regards,

Yoshi

Dear Alexis,

Thank you for your help.

I understood that the tf/tr spec are same in both GPIOs and WAKEUP pins mode.

It would help me if you corrected my understandings.

Best regards,

Yoshi

Hi Yoshiyuki,

Yes, that's right. The electrical characteristics are the same only remember that to trigger the event the pulse needs to be at least 45ns.
