Hello @Jeremy_He,

I've got one question: In case a pin is GPIO IN and selected as a wake up source, if that pin is kept as PAD KEEPING, could that pin still able to wake up the MCU during standby mode?

Best Regards,

Nam

Hi Nam,

The time pad keeping functioning is when MCU is reinitializing after wakeup, Like the below diagram. It won't affect the mode during standby mode. So the pin defined as wakeup function will always function as a wakeup pin during standby mode.

Best wishes.
