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

re gist er is used in conjunct i on with Sw it ch Fabric MAC Address Low Register

(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 Section 13.1.5.7, "Switch Fabric MAC Address Low Register (SWITCH_MAC_ADDRL)" for

information on how this address is loaded by the EEPROM Loader. Section 8.2.4, "EEPROM Loader,"

on page 113 contains additional details on using the EEPROM Loader.
