Description
KS8993F operating modes, defined as below:
(MCHS, MCCS)
(0, 0)
Description
Normal 3 port switch mode (3 MAC + 2 PHY)
MC mode is disabled.
Port 1 is either Fiber or UTP.
Port 2 is UTP.
Port 3 (MII) is enabled.
(0, 1)
Center MC mode (3 MAC + 2 PHY)
MC mode is enabled.
Port 1 is Fiber and has Center MC enabled.
Port 2 is UTP.
Port 3 (MII) is enabled.
(1, 0)
Terminal MC mode (2 MAC + 2 PHY)
MC mode is enabled.
Port 1 is Fiber and has Terminal MC enabled.
Port 2 is UTP.
Port 3 (MII) is disabled.
(1, 1)
Terminal MC mode (3 MAC + 2 PHY)
MC mode is enabled.
Port 1 is Fiber and has Terminal MC enabled.
Port 2 is UTP.
Port 3 (MII) is enabled.
Ipu
Power Down Detect
1 = normal operation
0 = power down detected
In Terminal MC mode (pin MCHS is ‘1’), a high to low transition to this pin
will cause port 1 (fiber) to generate and send out an “Indicate Terminal MC
Condition” OAM frame with the S0 status bit set to ‘1’.
Ipu
1= advertise the switch’s flow control capability via auto negotiation.
0 = will not advertise the switch’s flow control capability via auto negotiation.
Ipu
1 = enable auto negotiation on port 2.
0 = disable auto negotiation on port 2.
Ipd
1 = Force port 2 to 100BT if P2ANEN = 0.
0 = Force port 2 to 10BT if P2ANEN = 0.
Ipd
1 = port 2 default to full duplex mode if P2ANEN = 1 and auto negotiation
fails. Force port 2 in full duplex mode if P2ANEN = 0.
0 = port 2 default to half duplex mode if P2ANEN = 1 and auto negotiation
fails. Force port 2 in half duplex mode if P2ANEN = 0.
Ipd
1 = always enable (force) port 2 flow control feature.
0 = port 2 flow control feature enable is determined by auto negotiation
result.
Opu
1 = normal function
0 = MC in loop back mode, or MC abnormal conditions happen
Ipd
In MC loop back mode,
1 = Drop OAM frames and Ethernet frames with the following errors –
