Hello,

We are using the STM32U5 microcontroller and we want to utilize Stop Mode 2. Can the SysTick timer work in this mode, and can we use the SysTick interrupt to wake up from Stop Mode 2 ?

Thanks!

Hello @mghST125, welcome to ST community,

The systick timer has no wake-up capability in STOP modes, to know which timers/ peripherals can be used to wake up from stop2 mode, you can refer to table 100 "Functionalities depending on the working mode(1) (continued)" in RM0456 .
