Hi! Ilya!

You can find the address of the PHY interface in <W7500P PHY Reference v1.0.0 - English>.
You can see the information from addresses of registers for the PHY interface in chapter No. 2 Register Descriptions of this document.

Hi. Evgenij_Yumashev

W7500P has IP101G series phy.
So, please refer to IP101G datasheet. (below link)
<http://www.bdtic.com/DataSheet/ICplus/IP101G_DS_R01_20121224.pdf>

And then refer to w7500_x_miim.c file in W7500P library (below link)
