Port 0 Backpressure Enable (BP_EN_0)
This bit enables/disables the generation of half-duplex backpressure on
switch Port 0.
0: Disable backpressure
1: Enable backpressure
Port 0 Current Duplex (CUR_DUP_0)
This bit indicates the actual duplex setting of switch Port 0.
0: Full-Duplex
1: Half-Duplex
Port 0 Current Receive Flow Control Enable (CUR_RX_0)
This bit indicates the actual receive flow setting of switch Port 0
0: Flow control receive is currently disabled
1: Flow control receive is currently enabled
Port 0 Current Transmit Flow Control Enable (CUR_TX_FC_0)
This bit indicates the actual transmit flow setting of switch Port 0.
0: Flow control transmit is currently disabled
1: Flow control transmit is currently enabled
Port 0 Receive Flow Control Enable (RX_FC_0)
When the MANUAL_FC_0 bit is set, or Virtual Auto-Negotiation is disabled,
this bit enables/disables the detection of full-duplex Pause packets on switch
Port 0.
0: Disable flow control receive
1: Enable flow control receive
Port 0 Transmit Flow Control Enable (TX_FC_0)
When the MANUAL_FC_0 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
Port 0 Manual Flow Control Register (MANUAL_FC_0)
This read/write register allows for the manual configuration of the switch Port 0 flow control. This
register also provides read back of the currently enabled flow control settings, whether set manually
or Auto-Negotiated. Refer to
information.
