RO
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

Table 14. Format of Dynamic MAC Address Table (1K Entries) (continued)
Example:
Dynamic MAC Address Table Read (read the 1
st entry and retrieve the MAC table size)
Write to reg. 110 with 0x18 (read dynamic table selected)
Write to reg. 111 with 0x00 (trigger the read operation)
Then
Read reg. 112 (71-64) // if bit 71 = 1, restart (reread) from this register
Read reg. 113 (63-56)
Read reg. 114 (55-48)
Read reg. 115 (47-40)
Read reg. 116 (39-32)
Read reg. 117 (31-24)
Read reg. 118 (23-16)
Read reg. 119 (15-8)
Read reg. 120 (7-0)
MIB (Management Information Base) Counters
The KSZ8993M provides 34 MIB counters per port. These counters are used to monitor the port activity for
network management. The MIB counters have two format groups: “Per Port” and “All Port Dropped Packet.”

Table 15. Format of “Per Port” MIB Counters
“Per Port” MIB counters are read using indirect memory access. The base address offsets and address ranges for
all three ports are:
Port 1, base is 0x00 and range is (0x00-0x1f)
Port 2, base is 0x20 and range is (0x20-0x3f)
Port 3, base is 0x40 and range is (0x40-0x5f)
