Description
1, turn off all port’s LEDs (PxLED0, PxLED1, 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 MDIX
mode.
0, MDI mode.
1 = Perform MAC loopback, loop back path as follows:
E.g. set port 1 MAC Loopback (reg. 45, bit 0 = ‘1’), use
port 2 as monitor port. The packets will transfer
packets from port 1).
Setting reg. 77, 93, bit 0 = ‘1’ will perform MAC
loopback on port 3, 4 respectively with monitor port 2.
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 1).
