SMPS on STM32N657
Hello,Regarding the STM32N657, I'm not using the internal SMPS. My question is: Do we need to put capacitors on the 6 VDDSMPS pins or can they be left as no connect? Same question on the VLXSMPS pins... do we need the capacitors on these pins, or...
STM32U031 freezing IWDG counter in STOP 0 mode.
Hello Everyone,I am facing an issue with my MCU entering low-power mode.My idea is to freeze the Independent Watchdog (IWDG) counter in STOP mode so that the MCU will not reset due to the IWDG counter elapsing.From my understanding, this can be achie...
