2.6.5.4.2. Configuration Registers

You can access the 16 -/ 32-bit configuration registers via the Avalon® memory-mapped interface. The 16-bit configuration registers apply only to 2.5G, 1G/2.5G, and 1G/2.5G/10G (MGBASE-T) operating modes, whereas the 32-bit configuration registers apply only to 10M/100M/1G/2.5G/5G/10G (USXGMII) operating mode.

Observe the following guidelines when accessing the registers:

  • Do not write to reserved or undefined registers.
  • When writing to the registers, perform read-modify-write to ensure that reserved or undefined register bits are not overwritten.
