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 resolu-
tion status is reported in PHYCR[13:12].
1 = Advertise that the DTE (MAC) has implemented both the op-
tional MAC control sublayer and the pause function as specified in
clause 31 and annex 31B of 802.3u.
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 resolu-
tion status is reported in PHYCR[13:12].
1 = Advertise that the DTE (MAC) has implemented both the op-
tional MAC control sublayer and the pause function as specified in
clause 31 and annex 31B of 802.3u.
0= No MAC based full duplex flow control.

Strap, RW
10BASE-T Support:
1 = 10BASE-T is supported by the local device.
0 = 10BASE-T not supported.
4:0
Selector
<00001>, RW
Protocol Selection Bits:
These bits contain the binary encoded protocol selector supported
by this port. <00001> indicates that this device supports IEEE
802.3u.
