STM3FF407 a RTC

Ano - ale ak sa tie 3mA neprekrocia, nemal by s RTC byt problem.

Na toto je upozornovane na viacerych miestach aj v RM aj v DS, tak zo
poltucta krat. Ak toto niekto nedodrzi, tak je s prepacenim trotl a
zasluzi si aby sa mu krystal nerozbehol... ;-)

Ale ano, dobre o tom vediet, len ma zmiatla ta zmienka o stabilizatore.
