Hi guys, I am developing the final version of a PCB board for medical applications and I need to have an extremally good EMI and EMC performance. I have searched but I did not find anything related to unconnected pins in this situation.
How should I proceed with unconnected pins? Should I ground then? External or internal pull?
I am not really concern about power savings.
Ps: I am using Atxmega-A and Atxmega-E microcontrollers.
