Description
1, turn off all port’s LEDs (LEDx_2, LEDx_1, LEDx_0,
where “x” is the port number). These pins will be driven
high if this bit is set to one.
0, normal operation.
1, disable port’s transmitter.
0, normal operation.
1, restart auto-negotiation.
0, normal operation.
N/A
1, power down.
0, normal operation.
1, disable auto MDI/MDI-X function.
0, enable auto MDI/MDI-X function.
1, if auto MDI/MDI-X is disabled, force PHY into MDI
mode.
0, MDIX mode.
1 = Perform MAC loopback, loop back path as follows:
E.g. set port 1 MAC Loopback (reg. 29, bit 0 = ‘1’), use
port 2 as monitor port. The packets will transfer
packets from port 3, 4, 5).
5 respectively).
Setting reg. 45, 61, 77, 93, bit 0 = ‘1’ will perform MAC
loopback on port 2, 3, 4, 5 respectively.
0 = Normal Operation.
Start: Port 2 receiving (also can start to receive
Loop-back: Port 1’s MAC.
End: Port 2 transmitting (also can end at Port 3, 4,
