Ethernet Address Registers
All Ethernet address registers consist of two 32-bit registers that together contain a 48-bit Ethernet
address. Refer to
Table 53
for register bit assignments.
5.2.1
Port Address Tracking Registers
The port address tracking register set is described in
Table 54
. These registers continuously
monitor the source addresses of packets emanating from the corresponding ports. Refer to
Table 53
for bit assignments.

rptrAddrTrackNewLastSrcAddress
Port 1
48
070, 071
Stores the value of the last Source Address received.
Can also act as NewLastSourceAddress via SW. These
addresses power up unknown, but can be zeroed by
software.
Example Address: 00-20-7B-03-02-01
First Read:
msb

lsb
.
Second Read:
msb
XXXX0102

All addresses must read in order. Only the first read
updates the holding register. X

s are currently defined
as zeros.
