FWIW, the Twincat software is a free download.

These links provided me with the answer. The EEPROM is supposed to be
programmed via Ethernet connector. Beckhoff have special software for this and
I also see Twincat system manager, maybe it's just manager software according
to standard?

These pins are the Distributed Clock Sync (OUT) or
Latch (IN) signals. The direction is bitwise configurable.
Note: These signals are not driven (high impedance) until the EEPROM is
loaded.
Basic problem is I do not know how to get LAN9252 started. Crystal is up
and running but nothing happens then I insert a Ethernet cable. SPI is not
running since it read configuration from EEPROM but how do I program
configuration? Maybe I should program EEPROM before soldering it to board?
