ASP-BF609 EvalBoard Hardware question

Hi !

My question concerns the schematic of the evalboard and therefore a special part on sheet 4.

on this page there is a voltage divide connected to GND pin C3(GND63) which is also connected to a voltage divider and a testpoint TP3

whats the purpose of this part ? only for testing?

And also GND62(B2) is connected via 0Ohm resistor to ground.

For our new design it is ok to connect this to pins directly to gnd . or whats the background of this schematic???

kind regards chris
