I just saw Power on reset feature in Pic (https://microchipdeveloper.com/8bit:por). It can hold mcu a little bit until the power is stable, before starting the hardware initialization. I would like to know if this feature is avalilable on stm32.
I have a problem after powering up power supply (2.8V). Sometimes it doesn't work properly, sometime it works well. I suspect there is sometinng wrong when start up the mcu.
