Pin Function
KSZ8893FQL operating modes (defined below):
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’.
1 = Advertise the switch’s flow control capability via auto-negotiation.
0 = Will not advertise the switch’s flow control capability via auto-negotiation.
1 = Enable auto-negotiation on port 2.
0 = Disable auto-negotiation on port 2.
1 = Force port 2 to 100BT if P2ANEN = 0.
0 = Force port 2 to 10BT if P2ANEN = 0.
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.
1 = Always enable (force) port 2 flow control feature.
0 = Port 2 flow control feature enable is determine by the auto-negotiation result.
Power Down Detect
1 = Port 2 default to full duplex mode if P2ANEN = 1 and auto-negotiation fails. Force
