half duplex. Note that the default value of this register bit is configurable via the hardware configuration

pins, which allows the default operation of the PHY to be configured in unmanaged applications.

FD_10_ADV

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit is to advertise 10BASE-T full

duplex. Note that the default value of this register bit is configurable via the hardware configuration pins,

which allows the default operation of the PHY to be configured in unmanaged applications.

HD_10_ADV

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit is to advertise 10BASE-T half

duplex. Note that the default value of this register bit is configurable via the hardware configuration pins,

which allows the default operation of the PHY to be configured in unmanaged applications.

SELECTOR_ADV

Selector field is a 5-bit wide field, encoding 32 possible messages. This field always reads as 1'b1,

indicating that the PHY only supports IEEE Standard 802.3.

LP_NEXT_PAGE

Link Partner Next Page Bit. Next page exchange occurs after the base link code words have been

exchanged. Next page exchange consists of using the normal autonegotiation arbitration process to

send next page messages. Next page transmission ends when both ends of a link segment set their

next page bits to Logic 0, indicating that neither has anything additional to transmit.

0x0

LP_ACK

This bit is used by the internal handshaking in autonegotiation and must be ignored.

0x0

1: link partner has successfully received its link code word.

0: link partner has not received its link code word.

LP_REM_FLT

The link partner remote fault bit provides a standard transport mechanism for the transmission of

simple fault information.

0x0

LP_EXT_NEXT_PAGE_ABLE

The link partner extended next page bit indicates that the link partner supports transmission of

extended next page. The use of extended next page is orthogonal to the negotiated data rate,

medium, or link technology.

0x0

LP_APAUSE_ABLE

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit indicates that the link

partner advertises asymmetric pause operation for full duplex links.

0x0

LP_PAUSE_ABLE

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit indicates that the link

partner advertises pause operation for full duplex links.

0x0

LP_T_4_ABLE

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit indicates that the link

partner advertises 100BASE-T4.

0x0

LP_FD_100_ABLE

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit indicates that the link

partner advertises 100BASE-TX full duplex.

0x0

LP_HD_100_ABLE

The technology ability field is a 7-bit wide field (Bits[11:5] within this register) containing information

indicating supported technologies specific to the selector field value. This bit indicates that the link

partner advertises 100BASE-TX half duplex.
