The 1G/10G/25G Ethernet Subsystem is configured with AXI4-Lite registers to access the configuration and status signals.

For more information, see 1G/2.5G Ethernet PCS/PMA or SGMII LogiCORE IP Product Guide (PG047) and 10G/25G High Speed Ethernet Subsystem Product Guide (PG210). AXI Crossbar module is initiated within the IP to access the AXI4-Lite interface control and statistics registers for Gigabit Ethernet PCS-PMA and 10G MAC+PCS subsystem. This module is provided with a single user AXI4-Lite interface.

The AXI Crossbar IP is configured with 1-master and 2-slave interfaces. Both Gigabit Ethernet PCS-PMA and 10G/25G MAC+PCS subsystem control and status registers can be accessed with AXI4-Lite interface through AXI Crossbar. Refer to the AXI Interconnect LogiCORE IP Product Guide (PG059) for AXI Crossbar soft IP functionality.

The following are the configured base address locations for Gigabit Ethernet PCS-PMA and 10G/25G MAC+PCS subsystem control and status registers in the AXI Crossbar soft IP:
