3.1 Gigabit Ethernet Connection
The XMC-A825-16 ETHERNET Connector has a pinout according to the established RJ-45 standard as
shown in Figure Illustration. This connector also contains two Status LEDS which indicate the negotiated
Ethernet data rate and interface transmit activity.
This connector is only used when the on-board Intel Gigabit Ethernet Controller is not enabled. To use this
interface, the option PCI=0 must be set in the configuration file “XMC_A825.CFG” on the micro SD card
installed. See the Section entitled XMC-A825-16 Configuration
Figure 3-2 Gigabit Ethernet Connector layout
Table shows the corresponding Ethernet signal assignment for the RJ-45 connector.
