When LINKIF link status change interrupt flag is set, it
means auto-negotiation or parallel detection is
complete. Once auto-negotiation is complete, the MAC
registers related to Duplex mode must be reconfigured.
Determine the new Duplex mode by reading the
PHYDPX bit (ESTAT<10>). Once this is done, update
the MACON2, MACLCON, MAIPG and MABBIPG
registers as described in Section 8.9 “After Link
.

bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
PRST:
PHY Reset bit
1
= Perform PHY Reset. Hardware automatically clears this bit to ‘0’ when the Reset is complete.
0
= PHY is not in Reset (normal operation)
bit 14
PLOOPBK:
PHY Loopback Enable bit
1
= Loopback is enabled
0
= Normal operation
bit 13
SPD100:
PHY Speed Select Control bit(1)
1
= 100 Mbps
0
= 10 Mbps
bit 12
ANEN:
PHY Auto-Negotiation Enable bit
1
= Auto-negotiation is enabled. SPD100 and PFULDPX are ignored.
0
= Auto-negotiation is disabled. SPD100 and PFULDPX control the operating speed and duplex.
bit 11
PSLEEP:
PHY Sleep Enable bit
1
= PHY is powered down
0
= Normal operation
bit 10
Reserved:
Write as ‘0’, ignore on read
bit 9
RENEG:
Restart Auto-Negotiation Control bit
1
= Restart the auto-negotiation process. Hardware automatically clears this bit to ‘0’ when the
auto-negotiation process starts.
0
= Normal operation
bit 8
PFULDPX:
PHY Duplex Select Control bit(1)
1
= Full duplex
0
= Half duplex
bit 7
Reserved:
Write as ‘0’, ignore on read
bit 6-0
Reserved:
Ignore on read
Note 1:
Applicable only when auto-negotiation is disabled (ANEN = 0).
