wakeup pin only for pm_mode_extended_sleep mode

Hi Dialog,

Q1. my application has two sleep modes, pm_mode_extended_sleep and hibernation mode. Is it possible to set a wakeup pin only for waking up from pm_mode_extended_sleep mode but not works for hibernation? If possible, how to set the wakeup pin? my current setting will wake up the both of sleep modes.

Q2. the wakeup from hibernation is reset process, isn't it?

thanks for your help.

Hi csq,

Hi nigelyang,

Q1: It is not possible to set a wake-up pin only for waking up from extended sleep mode but not from hibernation. You have to activate the wake up controller for waking up both from extended sleep and from hibernation, so you are not able to wake up only from extended sleep mode.

Q2: The wake-up on reset procedure isn’t the only procedure that you are able to wake-up from hibernation. You can also wake up from hibernation either with any asynchronous external event by activating the wake-up or via USB Vbus.

I strongly recommend you to check thefigure 15 : Possible Device’s Statesof theStarting a Project教程。你能找到可用的导师ials and documentation of the DA14680 chip, from our support page.

Thanks, PM_Dialog
