Port 2 Full-Duplex Flow Control Enable Strap:
Configures the default value of the
Duplex Transmit Flow Control Enable (TX_FC_2)
and

when manual full-duplex control is selected. When
latched low, full-duplex Pause packet detection and
generation are disabled. When latched high, full-
duplex Pause packet detection and generation are
enabled. See

Note
Port 0(External MII) Speed Select Strap:
Together with the DUPLEX_POL_MII and
MII_DUPLEX pins, configures the base ability
values in the
Partner Base Page Ability Register
(VPHY_AN_LP_BASE_ABILITY).
This pin also configures the speed for Port 0 when
the Virtual Auto-Negotiation fails. When latched
low, 10Mbps is selected. When latched high,
100Mbps is selected.
Refer to
information.
See
Port 0(External MII) Duplex Polarity Strap:
Configures the polarity of the MII_DUPLEX pin for
Port 0.
If MII_DUPLEX = DUPLEX_POL_MII, full-duplex is
selected.
If MII_DUPLEX != DUPLEX_POL_MII, half-duplex
is selected.
Refer to
information.
See
Port 0(External MII) Backpressure Enable Strap:
Configures the default value for the
Backpressure Enable (BP_EN_MII)
0(External MII) Manual Flow Control Register
(MANUAL_FC_MII). When latched low,
backpressure is disabled. When latched high,
backpressure is enabled.
