Ethernet Configuration Registers
The registers in this section provide information about the Ethernet Configuration for the two ports on the board.
Important: Regardless if the board is configured for one or two Ethernet ports, the second IP address cannot be on the same Subnet as the First IP Address. The table below provides examples of valid and invalid IP Addresses and Subnet Mask Addresses.
