Hello,We are using STMU575 MCU and it's power saving mode STOP3.For verification purpose we are using NUCLEO-U575ZI-Q eval board, ST cube example PWR_LPMODE_RTC (STM32CubeU5-1.7.0). ST cube IDE version is: 1.18.0.I modified existing code little bit (...

Hello,We added code to SuspendTick, set S3WU interrupt before entry to stop 3 mode and resuming tick after invoking stop 3 function as suggested in sample code. It did not help but. Please suggest what else can be checked.We have two use cases: First...
