Description
Indicate the current state of port operation mode:
[000] = reserved.
[001] = still in auto-negotiation.
[010] = 10BASE-T half duplex.
[011] = 100BASE-TX half duplex.
[100] = reserved.
[101] = 10BASE-T full duplex.
[110] = 100BASE-TX full duplex.
[111] = PHY/MII isolate.
1 = Polarity is reversed.
0 = Polarity is not reversed.
0 = MDI
1 = Force link pass.
0 = Normal operation.
1 = Enable power save.
0 = Disable power save.
1 = Perform Remote loopback, loop back path as
follows:
will perform remote loopback on port 2, 3, 4, 5.
0 = Normal Operation.
Setting PHY ID address 0x2,3,4,5 reg. 1f, bit 1 = ‘1’
Port 1 (PHY ID address 0x1 reg. 1f, bit 1 = ‘1’)
Start: RXP1/RXM1 (port 1)
Loopback: PMD/PMA of port 1’s PHY
End: TXP1/TXM1 (port 1)
