Table 6-13. Negotiation Advertisement Register (ANAR), address 0x04h (continued)
Bit Bit Name Default Description
13 RF 0, RW Remote Fault:
1 = Advertises that this device has detected
a Remote Fault.
0 = No Remote Fault detected.
12 RESERVED 0, RW RESERVED for Future IEEE use: Write as
0, Read as 0
11 ASM_DIR 0, RW Asymmetric PAUSE Support for Full
Duplex Links:
The ASM_DIR bit indicates that asymmetric
PAUSE is supported.
Encoding and resolution of PAUSE bits is
defined in IEEE 802.3 Annex 28B, Tables
28B-2 and 28B-3, respectively. Pause
resolution status is reported in
PHYCR[13:12].
1 = Advertise that the DTE (MAC) has
implemented both the optional MAC control
sublayer and the pause function as specified
in clause 31 and annex 31B of 802.3.
0= No MAC based full duplex flow control.
10 PAUSE 0, RW PAUSE Support for Full Duplex Links:
The PAUSE bit indicates that the device is
capable of providing the symmetric PAUSE
functions as defined in Annex 31B.
Encoding and resolution of PAUSE bits is
defined in IEEE 802.3 Annex 28B, Tables
28B-2 and 28B-3, respectively. Pause
resolution status is reported in
PHYCR[13:12].
1 = Advertise that the DTE (MAC) has
implemented both the optional MAC control
sublayer and the pause function as specified
in clause 31 and annex 31B of 802.3.
0= No MAC based full duplex flow control.
9 T4 0, RO/P 100BASE-T4 Support:
1= 100BASE-T4 is supported by the local
device.
0 = 100BASE-T4 not supported.
8 TX_FD Strap, RW 100BASE-TX Full Duplex Support:
1 = 100BASE-TX Full Duplex is supported
by the local device.
0 = 100BASE-TX Full Duplex not supported.
7 TX Strap, RW 100BASE-TX Support:
1 = 100BASE-TX is supported by the local
device.
0 = 100BASE-TX not supported.
6 10_FD Strap, RW 10BASE-T Full Duplex Support:
1 = 10BASE-T Full Duplex is supported by
the local device.
