Description
Link partner 100 full capability.
Link partner 100 half capability.
Link partner 10 full capability.
Link partner 10 half capability.
1 = Enable cable diagnostic. AfterVCT test has
completed, this bit will be self-cleared.
0 = Indicate cable diagnostic test (if enabled) has
completed and the status information is valid for read.
00 = Normal condition
01 = Open condition detected in cable
10 = Short condition detected in cable
11 = Cable diagnostic test has failed
1 = Less than 10 meter short
Distance to the fault.
It’s approximately 0.4m*vct_fault_count[8:0]
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
N/A, don’t change
1 = Polarity is reversed
0 = Polarity is not reversed
1 = MDI-X
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)
