DESCRIPTION
Port 2 Backpressure Enable Strap: Configures the
default value for the
(BP_EN_2)
(MANUAL_FC_2). When configured low, backpressure is
disabled. When configured high, backpressure is enabled.
Port 2 Full-Duplex Flow Control Enable Strap:
Configures the default value of the
Transmit Flow Control Enable (TX_FC_2)
Duplex Receive Flow Control Enable (RX_FC_2)
Port 2 Manual Flow Control Register
which are used when manual full-duplex control is selected.
When configured low, full-duplex Pause packet detection
and generation are disabled. When configured high, full-
duplex Pause packet detection and generation are enabled.
Port 2 Manual Flow Control Enable Strap: Configures the
default value of the
Select (MANUAL_FC_2)
Control Register
flow control is determined by auto-negotiation (if enabled),
and symmetric PAUSE is advertised (bit 10 of the
PHY Auto-Negotiation Advertisement Register
(PHY_AN_ADV_x)
When configured high, flow control is determined by the
Port 2 Full-Duplex Transmit Flow Control Enable
(TX_FC_2)
Enable (RX_FC_2)
advertised (bit 10 of the
Advertisement Register (PHY_AN_ADV_x)
Port 0(External MII) Speed Select Strap: Together with
the duplex_pol_strap_mii and MII_DUPLEX pins,
configures the base ability values in the
Negotiation Link Partner Base Page Ability Register
(VPHY_AN_LP_BASE_ABILITY).
This pin configures the speed for Port 0 when the Virtual
Auto-Negotiation fails. When configured low, 10Mbps is
selected. When configured high, 100Mbps is selected.
Refer to
information.
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.
Port 0(External MII) Backpressure Enable Strap:
Configures the default value for the
Enable (BP_EN_MII)
Flow Control Register
configured low, backpressure is disabled. When configured
high, backpressure is enabled.
