Hi all,

i'm using STM32F407/F417 with 12MHz crystal,
and i would like to save power as possible, because i need to run it on batteries,
i need to have USB connected,
i read in manual that i could underclock ...

please could somebody direct me how to do it and to not loose usb connection ? so exactly: at one moment i need full swing and other moment i need to save power and it's not required to have fast execution,

thanks for all replies ...
