Table 47. Auto-Negotiation Advertisement Register (Address 4)
1. R/W = Read/Write
2. The default setting of Register bit 4.10 (PAUSE) is determined by pin 33/H8 at reset.
3. Default values of Register bits 4.5, 4.6, 4.7, and 4.8 are determined by LED/CFG n pins at reset. Refer to

Ignore.
1 = Remote fault.
0 = No remote fault.
Ignore.
Pause operation defined in Clause 40 and 27.
1 = Pause operation enabled for full-duplex links.
0 = Pause operation disabled.
1 = 100BASE-T4 capability is available.
0 = 100BASE-T4 capability is not available.
(The LXT971A does not support 100BASE-T4 but
allows this bit to be set to advertise in the auto-
negotiation sequence for 100BASE-T4 operation. An
external 100BASE-T4 transceiver could be switched in
if this capability is desired.)
1 = Port is 100BASE-TX full-duplex capable.
0 = Port is not 100BASE-TX full-duplex capable.
1 = Port is 100BASE-TX capable.
0 = Port is not 100BASE-TX capable.
1 = Port is 10BASE-T full-duplex capable.
0 = Port is not 10BASE-T full-duplex capable.
1 = Port is 10BASE-T capable.
0 = Port is not 10BASE-T capable.
<00001> = IEEE 802.3.
<00010> = IEEE 802.9 ISLAN-16T.
<00000> = Reserved for future auto-negotiation
development.
<11111> = Reserved for future auto-negotiation
development.
Unspecified or reserved combinations should not be
