Hello guys,


The datasheet and reference manual has divergent information about USB regulator when you don't want to use it.


The datasheet says to tie VREGIN and VOUT33 to GND using a 10K resistor.


The reference manual says to remain these pins floating. (see the picture)


My board need to get certification in EMI/EMC tests.


Which information should I follow?


Thank you!
