Physical Address[47:32]
This field contains the upper 16-bits (47:32) of the physical address of the
Switch Fabric MACs.
Switch Fabric MAC Address High Register (SWITCH_MAC_ADDRH)
This register contains the upper 16-bits of the MAC address used by the switch for Pause frames. This

(SWITCH_MAC_ADDRL). The contents of this register are optionally loaded from the EEPROM at
power-on through the EEPROM Loader if a programmed EEPROM is detected. The least significant
byte of this register (bits [7:0]) is loaded from address 05h of the EEPROM. The second byte (bits
[15:8]) is loaded from address 06h of the EEPROM. These EEPROM values are also loaded into the
Host MAC Address High Register
after the initialization process has completed.
