DP83867E: Incorrectly read PHY Identifier registers

Part Number: DP83867E

Hello, 

I'm using DP83867ERGZT and I'm trying to read PHY Identifier registers from 0x2h and 0x3h addresses.

My expectations when I read the datasheet are:

  • @0x2h, PHYIDR1 --> 0x2000h
  • @0x3h, PHYIDR2--> 0xA231h

What I read is:

  • 0x2h --> 0x4001h
  • 0x3h --> 0x4463h

The PHY otherwise works without a problem. Could you assist me on why I might be getting such incorrect values?

Thanks!
