Notes:
1. In the tables above, registers must be accessed as 64-bit registers, even when their widths are smaller. For such
registers, the remaining bits are “Reserved”, are ignored when written to, and are read back as zeroes.
2. All registers that are marked as “Reserved” are ignored when written to, and are read back as ones.
3. The contents of Internal Test Registers must be preserved to ensure correct operation.
4. The actual values saved in each Physical Address value are a 48-bit MAC Address in the lower 48 bits and a
valid bit at bit 63. The remaining bits (48 through 62) of these registers are also “Reserved” as explained in Note
1.
