7.1. Register Map

You can access the 32-bit configuration registers via the Avalon® memory-mapped interface as described in Avalon Memory-Mapped Interface Signals.
Table 23.  Register Map Overview
Address Range Usage Register Width Configuration
0x400–0x41F USXGMII 32 10M/100M/1G/2.5G/5G/10G (USXGMII)
Note: Refer to the F-tile Ethernet Hard IP User Guide and F-tile Architecture and PMA and FEC Direct PHY IP User Guide for register map of Ethernet and Transceiver Reconfiguration Interfaces.
Table 24.  Types of Register Access
Access Definition
RO Read only.
RW Read and write.
RWC Read, write, and clear. The user application writes 1 to the register bit(s) to invoke a defined instruction. The IP core clears the bit(s) upon executing the instruction.
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 operation to ensure that reserved or undefined register bits are not overwritten.
