BITS
31:0
Physical Address[31:0]
This field contains the lower 32-bits (31:0) of the physical address of the
Switch Fabric MACs.
Switch Fabric MAC Address Low Register (SWITCH_MAC_ADDRL)
This register contains the lower 32-bits of the MAC address used by the switch for Pause frames. This
r e g i s t e r i s u s e d i n c o n j u n c t i o n w i t h
(SWITCH_MAC_ADDRH). 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 01h of the EEPROM. The most significant byte
(bits [31:24]) is loaded from address 04h of the EEPROM. These EEPROM values are also loaded
into the
field after the initialization process has completed.
Refer to
this register. Refer to
EEPROM Loader.
