Table 18. Dynamic MAC Address Table
Examples:
(1) Dynamic MAC Address Table Read (read the 1
st entry), and retrieve the MAC table size
Write to Register 110 with 0x18 (read dynamic table selected)
Write to Register 111 with 0x0 (trigger the read operation) and then
Read Register 112 (71-64)
Read Register 113 (63-56); // the above two registers show # of entries
Read Register 114 (55-48) // if bit 55 is 1, restart (reread) from this register
Read Register 115 (47-40)
Read Register 116 (39-32)
Read Register 117 (31-24)
Read Register 118 (23-16)
Read Register 119 (15-8)
Read Register 120 (7-0)
(2) Dynamic MAC Address Table Read (read the 257
th entry), without retrieving # of entries information
Write to Register 110 with 0x19 (read dynamic table selected)
Write to Register 111 with 0x1 (trigger the read operation) and then
Read Register 112 (71-64)
Read Register 113 (63-56)
Read Register 114 (55-48) // if bit 55 is 1, restart (reread) from this register
Read Register 115 (47-40)
Read Register 116 (39-32)
Read Register 117 (31-24)
Read Register 118 (23-16)
Read Register 119 (15-8)
Read Register 120 (7-0)
