Scalable Low Latency Ethernet 10G MAC using Intel Arria 10 1G/10G PHY

1G/10G MAC

1G/10G MAC registers are applicable to both design examples.

The base address of the 1G/10G MAC registers are defined as follows:

Channel 1G/10G MAC Register Base Address
0 MSA0 + 0x02_8000
1 MSA0 + 0x03_8000
2 MSA0 + 0x04_8000
3 MSA0 + 0x05_8000
4 MSA0 + 0x06_8000
5 MSA0 + 0x07_8000
6 MSA0 + 0x08_8000
7 MSA0 + 0x09_8000
8 MSA0 + 0x0A_8000
9 MSA0 + 0x0B_8000
10 MSA0 + 0x0C_8000
11 MSA0 + 0x0D_8000
Note: For the description of each 1/10G MAC register, refer to the Low Latency Ethernet 10G MAC User Guide.
Note: The address offset in this table is in byte, while the register map table in the Low Latency Ethernet 10G MAC User Guide is in word.
