Description
Assigned to the 19th through 24th bits of the OUI.
Six-bit manufacturer’s model number.
Four-bit manufacturer’s revision number.
Description
1 = Next Page enabled.
0 = Next Page disabled.
This bit will be set internally after receiving three consecutive
and consistent FLP bursts.
1 = Remote fault supported.
0 = No remote fault.
For future technology.
Full Duplex Flow Control:
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 31 B of 802.3u.
0 = No MAC-based full duplex flow control.
NetPHY-1LP device does not support 100BASE-T4 function,
i.e., this bit ties to zero.
1 = 100BASE-TX Full Duplex.
0 = No 100BASE-TX Full Duplex ability.
Default is set by Register 1.14.
1 = 100BASE-TX Half Duplex.
0 = No 100BASE-TX Half Duplex capability.
Default is set by Register 1.13
1 = 10 Mbps Full Duplex.
0 = No 10 Mbps Full Duplex capability.
Default is set by Register 1.12.
1 = 10 Mbps Half Duplex.
0 = No 10 Mbps Half Duplex capability
Default is set by Register 1.11.
[00001] = IEEE 802.3.
