Bits
Description
Type
0
Port 0 Full-Duplex Manual Flow Control Select (MANUAL_FC_0)
R/W
This bit toggles flow control selection between manual and Auto-Negotiation. _{Note 16}
0: If Auto-Negotiation is enabled, the Auto-Negotiation function deter-
mines the flow control of switch Port 0 (RX_FC_0 and TX_FC_0 values
ignored). If Auto-Negotiation is disabled, the RX_FC_0 and TX_FC_0
values are used.
1: TX_FC_0 and RX_FC_0 bits determine the flow control of switch Port
0 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 17
Note 13: The default value of this field is determined by the BP_EN_strap_0 configuration strap.
Note 14: The default value of this bit is determined by multiple strap settings.
Note 15: The default value of this field is determined by the FD_FC_strap_0 configuration strap.
Note 16: This bit is RO when in External MAC modes.
Note 17: In External MAC modes, this bit has a default value of 1 and is not re-written by the EEPROM Loader. Oth-
erwise, the default value of this field is determined by the manual_FC_strap_0 configuration strap.
