Hello TVanL3,
Thank you for contacting Intel Customer Support.
First, we would like to apologize for the delay in our response.
Can you please let us know if you have access to XDP blue box? Like the one listed here:
https://designintools.intel.com/In_Target_Probe_Debug_Tool_Kit_p/itpxdp3brext.htm
Or do you need to read the register thru OS? If so what is the OS you are using for this?

Hello Sergio,
I don't have a XDP blue box so if it is possible to access registers thru OS that would be better :)
I am using a Ubuntu server 16.04

Hello TVanL3,
We just received an update on your case:
Broadwell supports four PCIe ports: one is DMI port0 (00:00.0) and port 1.a (00:01.0) x8, port 2.a (00:02.0) x16 and port 3.a (00:03.0) x16.
So, you have to select one port and use the command:
setpci -s 00:02.0 254.l
If you do not know which port to read, you can use number lspci –t –v and identify the attached PCIe card.
