suppressed from transmission. Resetting the chip restores the default bit values. Reading
the register returns the values last written to the corresponding bits, or else the default
values if no write has been completed since the last chip reset. Even though bit 9 (advertise
100BASE-T4) is writable, it should never be set since the ST802RT1x does not support T4
operation.
Advertised selector: Bits 4:0 of the advertisement register contain the fixed value “00001”,
indicating that the chip belongs to the 802.3 class of PHY transceivers
RN05 [0d05, 0x05]: Auto-negotiation link partner ability register
LP next page: Bit 15 of the link partner ability register returns a value of “1” when the link
partner implements the next page function and has next page information that it wants to
transmit.
LP ack: Bit 14 of the link partner ability register is used by auto-negotiation to indicate that a
device has successfully received its link partner's link code word.
LP remote fault: Bit 13 of the link partner ability register returns a value of “1” when the link
partner signals that a remote fault has occurred. The ST802RT1x simply copies the value to
this register and does not act upon it.
1 -> Link partner desires next page transfer
0 -> Link partner does not desire next page transfer
1 -> Link partner acknowledges reception of the ability data
word
0 -> Acknowledge not yet received
1 -> Remote fault indicated by link partner
0 -> No remote fault indicated by link partner
--
1 -> LP supports asymmetric pause (MAC level: clause 31,
annex 31B of 802.3u)
0 -> LP has no MAC-based full-duplex flow control.
1 -> LP supports symmetric pause (MAC level: clause 31,
annex 31B of 802.3u)
0 -> LP has no MAC-based full-duplex flow control.
1 -> LP supports 100BASE-T4
0 -> LP does not support 100BASE-T4
1 -> LP supports 100BASE-TX full-duplex
0 -> LP does not support 100BASE-TX full-duplex
1 -> LP supports 100BASE-TX
0 -> LP does not support 100BASE-TX
1 -> LP supports 10BASE-T full-duplex
0 -> LP does not support 10BASE-T full-duplex
1 -> LP supports 10BASE-T
0 -> LP does not support 10BASE-T
