PCS Configuration Register Space
This section describes the PCS registers. Use the registers to configure the PCS function or retrieve its status.
In MAC and PCS variations, the PCS registers occupy the MAC register space and you access these
registers via the MAC 32-bit Avalon-MM control interface. PCS registers are 16 bits wide, they
Note:
therefore occupy only the lower 16 bits and the upper 16 bits are set to 0. The offset of the first PCS
register in this variation is mapped to dword offset 0x80.
If you instantiate the IP core using the MegaWizard Plug-in Manager flow, use word addressing to access
the register spaces. When you instantiate MAC and PCS variations, map the PCS registers to the respective
dword offsets in the MAC register space by adding the PCS word offset to the offset of the first PCS. For
example,
• In PCS only variation, you can access the if_mode register at word offset 0x14.
• In MAC and PCS variations, map the if_mode register to the MAC register space:
• Offset of the first PCS register = 0x80
• if_mode word offset = 0x14
• if_mode dword offset = 0x80 + 0x14 = 0x94
If you instantiate the MAC and PCS variation using the Qsys system, access the register spaces using byte
addressing. Convert the dword offsets to byte offsets by multiplying the dword offsets by 4. For example,
• For MAC registers:
• comand_config dword offset = 0x02
• comand_config byte offset = 0x02 × 4 = 0x08
