AN_LP_ADV_B10L_EEE

Link Partner 10BASE-T1L EEE Ability. This bit reports if the link partner is

capable of using 10BASE-T1L energy efficient Ethernet.

0x0

AN_LP_ADV_B10L_TX_LVL_HI_ABL

Link Partner 10BASE-T1L High Level Transmit Operating Mode Ability.

This bit reports whether the link partner is capable of transmitting in the

high level (2.4 V p-p) transmit operating mode. This bit is used with

AN_LP_ADV_B10L_TX_LVL_HI_REQ to configure 10BASE-T1L transmission

level (2.4 V p-p or 1.0 V p-p). See the AN_ADV_B10L_TX_LVL_HI_REQ bit for

more details.

0x0

AN_LP_ADV_B10L_TX_LVL_HI_REQ

Link Partner 10BASE-T1L High Level Transmit Operating Mode Request. This

bit reports whether the link partner is requesting that high level (2.4 V p-p)

transmit operating mode is used. See the AN_ADV_B10L_TX_LVL_HI_REQ bit

for more details.

0x0

AN_LP_ADV_B10S_HD

Link Partner 10BASE-T1S Half-Duplex Ability. This bit reports if the link partner

is capable of using 10BASE-T1S half duplex.

BASE-T1 Autonegotiation Next Page Transmit Register, Bits[15:0]

Device Address: 0x07; Register Address: 0x0208, Reset: 0x2001, Name: AN_NEXT_PAGE_L

This address corresponds to the BASE-T1 autonegotiation next page transmit register, Bits[15:0], specified in Clause 45.2.7.23 of Standard

802.3. On power-up or autonegotiation reset, this register contains the default value, which represents a message page with the message code

set to null. Write AN_NEXT_PAGE_M and AN_NEXT_PAGE_H before AN_NEXT_PAGE_L.

AN_NP_NEXT_PAGE_REQ

Next Page Request. This bit indicates to the link partner that the PHY wants to send a next

page. See IEEE Standard 802.3 Subclause 98.2.1.2.9.

0x0

R/W

AN_NP_ACK

Next Page Acknowledge. See IEEE Standard 802.3 Subclause 98.2.1.2.8.

0x0

AN_NP_MESSAGE_PAGE

Next Page Encoding. Indicates encoding of next page, as follows:

0x1

R/W

0: unformatted next page.

1: message next page.

AN_NP_ACK2

Acknowledge 2. Indicates whether the PHY can comply with the message. See IEEE

Standard 802.3 Subclause 28.2.3.4.6.

0x0

R/W

AN_NP_TOGGLE

Toggle Bit. The toggle bit is used to synchronize pages between the PH_YS. This always

reads as 0 (the toggle bit is set automatically by the arbitration state machine).

0x0

[10:0]

AN_NP_MESSAGE_CODE

Message/Unformatted Code Field. For a message page (AN_NP_MESSAGE_PAGE = 1),

the valid values are defined in IEEE Standard 802.3.

0x1

R/W

1: null message.

5: organizationally unique identifier tagged message.

6: autonegotiation device identifier tag code.
