Port 0 Backpressure Enable (BP_EN_MII)
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_MII)
This bit indicates the actual duplex setting of the switch Port 0.
0: Full-Duplex
1: Half-Duplex
Port 0 Current Receive Flow Control Enable (CUR_RX_FC_MII)
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_MII)
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_MII)
When the MANUAL_FC_MII 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_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
Port 0(External MII) Manual Flow Control Register (MANUAL_FC_MII)
This read/write register allows for the manual configuration of the switch Port 0(External MII) flow
control. This register also provides read back of the currently enabled flow control settings, whether
set manually or Auto-Negotiated. Refer to
additional information.
