Dynamic MAC Address Table
The Dynamic MAC address is a read only table.
Bit
Default Value
R/W
Description
71
RO
Data not ready
1: specifies that the entry is not ready, continue retrying until bit is set to 0
0: specifies that the entry is ready
70-67
RO
Reserved
66
1
RO
MAC empty
1: specifies that there is no valid entry in the table
0: specifies that there are valid entries in the table
65-56
0x000
RO
No of valid entries
Indicates how many valid entries in the table
0x3ff means 1 K entries
0x001 means 2 entries
0x000 and bit 66 = 0 means 1 entry
0x000 and bit 66 = 1 means 0 entry
55-54
RO
Time Stamp
Specifies the 2-bit counter for internal aging.
53-52
00
RO
Source port
Identifies the source port where FID+MAC is learned:
00: port 1
01: port 2
10: port 3
51-48
0x0
RO
FID
Specifies the filter ID.
47-0
0x0000_0000_0000
RO
MAC Address
Specifies the 48-bit MAC address.
Table 19. Dynamic MAC Address Table Format (1024 Entries)
Dynamic MAC Address Lookup Example:
Dynamic MAC Address Table Read (read the first entry at indirect address offset 0 and retrieve the MAC
table size)
Write to reg. IACR with 0x1800 (set indirect address and trigger a read dynamic MAC table operation)
Then
Read reg. IADR1 (dynamic MAC table bits 71-64) // If bit 71 = 1, restart (reread) from this register
Read reg. IADR3 (dynamic MAC table bits 63-48)
Read reg. IADR2 (dynamic MAC table bits 47-32)
Read reg. IADR5 (dynamic MAC table bits 31-16)
Read reg. IADR4 (dynamic MAC table bits 15-0)
