This field contains the upper 16-bits (47:32) of the physical address of the
Switch Fabric MACs. Bits 41 and 10 are ignored if
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. The Host can update the contents of this field
after the initialization process has completed.
Refer to
information on how this address is loaded by the EEPROM Loader.
