-Communication takes place via a normal SPI interface in 16-bit transfer. The setting options are so versatile that you get desperate at the beginning until you finally want to receive. Therefore, here is the init sequence that was successful for me:+Communication takes place via a normal SPI interface in 16-bit transfer.

 When it comes to sockets (Power / Ethernet), I'm still a fan of thru-hole - because of the stability. The soldering took place again in the pizza pan as described in the c't Hacks. When it comes to sockets (Power / Ethernet), I'm still a fan of thru-hole - because of the stability.
