FAQ for XMC4800 EtherCAT

Hi,

From the RM:
"EtherCAT slave devices with Ethernet Physical Layer usually support MII interfaces,
some do also support the RMII interface. Since RMII PHYs include TX FIFO’s, they
increase the packet forwarding delay of an EtherCAT slave device as well as the jitter.
RMII as a Ethernet Physical Layer is not supported by the XMC4[78]00 due to these
reasons."
