Table 12: Format of Dynamic MAC Table (1K entries)
Bit
Name
R/W
Description
Default
71
Data not
ready
RO
= 1, entry is not ready, retry until this bit is
set to 0
= 0, entry is ready
70-67
Reserved
RO
Reserved
66
MAC empty
RO
= 1, there is no valid entry in the table
= 0, there are valid entries in the table
1
65-56
No of valid
entries
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
00_0000_0000
55-54
Time Stamp
RO
2 bits counter for internal aging
53-52
Source port
RO
The source port where FID+MAC is learned
00, port 1
01, port 2
10, port 3
00
51-48
FID
RO
Filter ID
0x0
47-0
MAC Address
RO
48 bits MAC address
0x0000_0000_0000
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 KS8993F 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”.
