Flow Control
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.
This bit defaults to 0, indicating that the
LU3X34FT does not support 100Base-
T4.
This 4-bit field contains the advertised
ability of this PHY. At powerup or reset,
the logic level of 100FD, 100HD, 10FD,
and 10HD pins are latched into bits 8
through 5, respectively.
These 5 bits are hardwired to 00001h,
indicating that the LU3X34FT supports
IEEE802.3 CSMA/CD.
