I believe that the net name on CN7-4 should be PD3.

Hello @Karl Yamashita @Andrew Neil 

After checking with our HW team, I can confirm that both connectors CN7-3 and CN7-4 are mapped to the same pin of the MCU (PD2).

Best Regards.

Fig 7 in UM2953 is the same:

PS:

PD3 is on CN10.1 both in schematic and in UM2953 Fig 7

    As @Andrew Neil, PD3 is on CN10, which i missed.

    Though it doesn't make sense to have PD3 by itself when it could have been grouped with the other 3 PDx pins. Unless there is a reason to have PD3 on CN10?
