Hello all,
I am using the STM32U5A5QJ in a project and I had a question about some of the wake-up modes. I would like the microcontroller to be in stop mode 3 most of the time until it receives an interrupt from a sensor to return to normal mode. The data sheet seems to specify two ways of doing this and I’m wondering which is correct or if both can be used.
They both seem to say that they can be used to wake-up from stop mode, is this correct or should one be used over the other?
Thanks for your help,

Helll @bjackson96 and welcome to the ST COMMUNITY 😊.
According to the RM0456, you can exit the STOP 3 mode using WKUPx pin edge, RTC/TAMP event/interrupt, NRST pin external reset, IWDG reset, BOR reset.
Best Regards.
