1G/10GbE PHY Register Definitions
You can access the 1G/10GbE registers using the Avalon-MM PHY management interface with word
addresses and a 32-bit embedded processor. A single address space provides access to all registers.
Notes:
Unless otherwise indicated, the default value of all registers is 0.
Writing to reserved or undefined register addresses may have undefined side effects.
To avoid any unspecified bits to be erroneously overwritten, you must perform read-modify-writes to
change the register values.
