Note 13.4

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 45 for more information.

Note 13.5

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 60 for additional information.

Note 13.6

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 45 for more information.

Note 13.7

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 45 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

0: Disable flow control transmit

1: Enable flow control transmit

R/W

Note 13.6

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
