MAC empty
1, there is no valid entry in the table.
RO
1
0, there are valid entries in the table.
67-58
No of valid entries
Indicates how many valid entries in the table:
RO
0
0x3ff means 1K entries
0x1 means 2 entries
0x0 and bit 68 = 0: means 1 entry
0x0 and bit 68 = 1: means 0 entry
57-56
Time stamp
2-bit counters for internal aging.

Table 14. Dynamic MAC Address Table
Examples:
(1) Dynamic MAC Address Table Read (read the 1st entry), and retrieve the MAC table size
Write to reg110 with 0x18 (read dynamic table selected)
Write to reg111 with 0x0 (trigger the read operation )
Then
Read reg112 (68-64)
Read reg113 (63-56) ; // the above two registers show # of entries
Read reg114 (55-48) // if bit 55 is 1, restart(reread) from this register
Read reg115 (47-40)
Read reg116 (39-32)
Read reg117 (31-24)
Read reg118 (23-16)
Read reg119 (15-8)
Read reg120 (7-0)
(2) Dynamic MAC Address Table Read (read the 257th entry), without retrieving # of entries info
Write to reg110 with 0x19 (read dynamic table selected)
Write to reg111 with 0x1 (trigger the read operation)
Then
Read reg114 (55-48) // if bit 55 is 1, restart (reread) from this register
Read reg115 (47-40)
Read reg116 (39-32)
Read reg117 (31-24)
Read reg118 (23-16)
Read reg119 (15-8)
Read reg120 (7-0)
