SMSC LAN9311/LAN9311i 231 Revision 1.4 (08-19-08)
DATASHEET
Note 14.4 The default value of this field is determined by the BP_EN_strap_1 configuration strap. The
strap values are loaded during reset and can be re-written by the EEPROM Loader. Once
the EEPROM Loader re-writes the values, this register is updated with the new values.
See Section 4.2.4, "Configuration Straps," on page 40 for more information.
Note 14.5 The default value of this bit is determined by multiple strap settings. The strap values are
loaded during reset and can be re-written by the EEPROM Loader. Once the EEPROM
Loader re-writes the values, this register is updated with the new values. Refer to Section
6.2.3, "Flow Control Enable Logic," on page 58 for additional information.
Note 14.6 The default value of this field is determined by the FD_FC_strap_1 configuration strap. The
strap values are loaded during reset and can be re-written by the EEPROM Loader. Once
the EEPROM Loader re-writes the values, this register is updated with the new values.
See Section 4.2.4, "Configuration Straps," on page 40 for more information.
Note 14.7 The default value of this field is determined by the manual_FC_strap_1 configuration strap.
The strap values are loaded during reset and can be re-written by the EEPROM Loader.
Once the EEPROM Loader re-writes the values, this register is updated with the new
values. See Section 4.2.4, "Configuration Straps," on page 40 for more information.

Port 1 Full-Duplex Transmit Flow Control Enable (TX_FC_1)
When the MANUAL_FC_1 bit is set, or Auto-Negotiation is disabled, this bit
enables/disables full-duplex Pause packets to be generated on switch Port
1.
0: Disable flow control transmit
1: Enable flow control transmit

Port 1 Full-Duplex Manual Flow Control Select (MANUAL_FC_1)
This bit toggles flow control selection between manual and auto-negotiation.
0: If auto-negotiation is enabled, the auto-negotiation function
determines the flow control of switch Port 1 (RX_FC_1 and TX_FC_1
values ignored). If auto-negotiation is disabled, the RX_FC_1 and
TX_FC_1 values are used.
1: TX_FC_1 and RX_FC_1 bits determine the flow control of switch Port
1 when in full-duplex mode
