1—Capable of next page function
0—Not capable of next page function
This bit is defaults to 0, indicating that
LU3X34FTR is not next page capable.
Reserved.
1—Remote fault has been detected
0—No remote fault has been detected
This bit is written by serial management
interface for the purpose of communicat-
ing the remote fault condition to the auto-
negotiation link partner.
These bits default to 0.
1—MAC sublayer is capable of pause-
based flow control
0—MAC sublayer not capable of pause-
based flow control
This bit advertises the MAC sublayer has
pause/flow control capability of operation
when set in full-duplex mode. This must
be set only when the PHY is advertising
10FD/100FD modes. At hardware reset,
this bit is set to 1, if the PAUSE pin
detects logic 1.
Note:
It is the user’s responsibility to
ensure that the flow control bit is set only
when the PHY is advertising
10FD/100FD modes.
This bit defaults to 0, indicating that the
LU3X34FTR does not support
100Base-T4.
This 4-bit field contains the advertised
ability of this PHY. At powerup or reset,
the logic level of 100FDEN, 100HDEN,
10FDEN, and 10HDEN pins are latched
into bits 8 through 5, respectively.
These 5 bits are hardwired to 00001h,
indicating that the LU3X34FTR supports
IEEE802.3 CSMA/CD.
