I have a question regarding this code: Is it normal that it does not enable a weak pull-up (100 k) on UART3_RXD's pad? According to the schematic history, the pull-down R6001 (10 k) has been added to UART3_RXD for revision 2. By default, the pad of this pin has its keeper enabled, not its pull, so everything is fine with this code for revision 2, but what about revision 1?
I don't know the history about this change between rev1 versus rev2. I would need to check with the board designer.
