DATASHEET
Note 14.12 The default value of this field is determined by the BP_EN_strap_mii configuration strap.
The strap value is loaded during reset and can be re-written by the EEPROM Loader. Once
the EEPROM Loader re-writes the value, this register is updated with the new values. See
Section 4.2.4, "Configuration Straps," on page 40 for more information.
Note 14.13 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 14.14 The default value of this field is determined by the FD_FC_strap_mii configuration strap.
The strap value is loaded during reset and can be re-written by the EEPROM Loader. Once
the EEPROM Loader re-writes the value, this register is updated with the new values. See
Section 4.2.4, "Configuration Straps," on page 40 for more information.
Note 14.15 The default value of this field is determined by the manual_FC_strap_mii configuration
strap. The strap value is loaded during reset and can be re-written by the EEPROM
Loader. Once the EEPROM Loader re-writes the value, this register is updated with the
new values. See Section 4.2.4, "Configuration Straps," on page 40 for more information.
1
Port 0 Transmit Flow Control Enable (TX_FC_MII)
When the MANUAL_FC_MII bit is set, or Virtual Auto-Negotiation is
disabled, this bit enables/disables full-duplex Pause packets to be generated
on switch Port 0.
0: Disable flow control transmit
1: Enable flow control transmit

0
Port 0 Full-Duplex Manual Flow Control Select (MANUAL_FC_MII)
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 0 (RX_FC_MII and
TX_FC_MII values ignored). If auto-negotiation is disabled, the
RX_FC_MII and TX_FC_MII values are used.
1: TX_FC_MII and RX_FC_MII bits determine the flow control of switch
Port 0 when in full-duplex mode
