Ethernet Configuration

The EVB is fitted with a standard RJ45 Ethernet connector (J7) and a DP83848C 10/100 Ethernet
transceiver (U6). This is however not used in conjunction with the S32R274RRUEVB daughter card
since it is fitted with its own Gb Ethernet physical interface and RJ45 connector. Please see section 4 for
details.
