typo/unclear in stm32f411's datasheet
Hi community,
after searching quite a long time for a bug on my board I found it. It was due to an unclear phrasing of the stm32f411's datasheet in table8/p39: for the QFP64 package pin 13 is not only vref but also VDDA.
It would be much clearer to write VREF/VDDA in that row.

Regards
