Bits
Description
Type
0
Port 1 Full-Duplex Manual Flow Control Select (MANUAL_FC_1)
R/W
This bit toggles flow control selection between manual and Auto-Negotiation. _{Note 7}
0: If Auto-Negotiation is enabled, the Auto-Negotiation function deter-
mines 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.
Note:
In External MAC modes, this bit is forced high. Full-duplex flow
control should be controlled manually by the host based on the
external PHYs Auto-Negotiation results.
Default
Note 8
Note 4: The default value of this field is determined by the BP_EN_strap_1 configuration strap.
Note 5: The default value of this bit is determined by multiple strap settings.
Note 6: The default value of this field is determined by the FD_FC_strap_1 configuration strap.
Note 7: This bit is RO when in External MAC modes.
Note 8: The default value of this field is determined by the operating mode. In External MAC modes, it is 1, and the
bit is not re-written by the EEPROM Loader. For all other operating modes, the default value is determined
by the manual_FC_strap_1 configuration strap.
