1.4.4.1. MAC Registers

For the description of each MAC register, refer to the 10-Gbps Ethernet MAC Megacore Function User Guide. The address offset in the following tables is in byte, while the register map table in the 10-Gbps Ethernet MAC Megacore Function User Guide is in word.

Note: Altera recommends maintain the register settings for this module as set in the reference design for optimum operation.
