Registers 104 to 109 define the switching engine’s MAC address. This 48-bit address is used as the source address
for MAC pause control frames.
Register 104 (0x68): MAC Address Register 0
Register 105 (0x69): MAC Address Register 1
Register 106 (0x6A): MAC Address Register 2
Register 107 (0x6B): MAC Address Register 3
Register 108 (0x6C): MAC Address Register 4
Register 109 (0x6D): MAC Address Register 5
Use registers 110 and 111 to read or write data to the static MAC address table, VLAN table, dynamic MAC address
table, or the MIB counters.
Register 110 (0x6E): Indirect Access Control 0
Register 111 (0x6F): Indirect Access Control 1
Note: A write to reg. 111 will actually trigger a command. Read or write access will be decided by bit 4 of reg. 110.
