Hello Champs,
If F280049 internal PGAs are not used, would you please kindly suggest how to treat PGAx_GND pins? Is it necessary to connect them to Vss? Thanks!
Best Regards,
Linda

Hi Linda,
PGAx_GND should be tied to VSSA if not used. Please look at section "4.6 Connections for Unused Pins" in the data manual.
