Description
1 = Drop OAM frames and Ethernet frames with the following errors –
CRC,
0 = Drop OAM frames only. Loop back all Ethernet frames including those
0 = perform MC loop back at MAC of port 2
1 = reserve. Do not use.
Port 2 LED Indicator

Port 2 auto MDI/MDI-X
Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled
1 = enable auto negotiation on port 1
0 = disable auto negotiation on port 1
1 = Force port 1 to 100BT if P1ANEN = 0.
0 = Force port 1 to 10BT if P1ANEN = 0.
1 = port 1 default to full duplex mode if P1ANEN = 1 and auto negotiation
0 = port 1 default to half duplex mode if P1ANEN = 1 and auto negotiation
1 = always enable (force) port 1 flow control feature
0 = port 1 flow control feature enable is determined by auto negotiation
undersize, oversize. Loop back Ethernet frames with only good CRC
and valid length.

Note: Internal pull down is weak; it will not turn ON the LED.
Note: An external 1K pull down is needed on this pin if it is connected
