DESCRIPTION
Port 1 Speed Select Strap: Configures the default value
for the
the PHY_BASIC_CTRL_1 register (See
When configured low, 10 Mbps is selected. When
configured high, 100 Mbps is selected.
This strap also affects the default value of the following bits:
Refer to the respective register definition sections for
additional information.
Port 1 Duplex Select Strap: Configures the default value
for the
PHY_BASIC_CTRL_1 register (See
When configured low, half-duplex is selected. When
configured high, full-duplex is selected.
This strap also affects the default value of the following bits:
Refer to the respective register definition sections for
additional information.
Port 1 Backpressure Enable Strap: Configures the
default value for the
(BP_EN_1)
(MANUAL_FC_1). When configured low, backpressure is
disabled. When configured high, backpressure is enabled.
Port 1 Full-Duplex Flow Control Enable Strap:
Configures the default value of the
Transmit Flow Control Enable (TX_FC_1)
Duplex Receive Flow Control Enable (RX_FC_1)
Port 1 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.
