I work on design with STM32L452RET6P and I'm considering power managment. I've got some voltage regulators that needs high voltage on SHDN pin and i want to use GPIO to keep this regulators on. I have read datasheet, and i found information that in StadBy I/Os can be configured with internal pull-up, pull-down or floating. My question is: Is it enough to configure pin, pull-up,out, and set high before entry to Standby to keep this pin high during StandBy?
Thank you for understending but i must be sure before design PCB.
