Description
KS8993F operating modes, defined as below:
Power Down Detect
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.
1 = port 2 default to full duplex mode if P2ANEN = 1 and auto negotiation
0 = port 2 default to half duplex mode if P2ANEN = 1 and auto negotiation
1 = always enable (force) port 2 flow control feature.
0 = port 2 flow control feature enable is determined by auto negotiation
1 = normal function
0 = MC in loop back mode, or MC abnormal conditions happen
In MC loop back mode,
(MCHS, MCCS)
1 = normal operation
0 = power down detected
result.
fails. Force port 2 in full duplex mode if P2ANEN = 0.
fails. Force port 2 in half duplex mode if P2ANEN = 0.
