Port 2 Backpressure Enable (BP_EN_2)
This bit enables/disables the generation of half-duplex backpressure on
switch Port 2.
0: Disable backpressure
1: Enable backpressure
Port 2 Current Duplex (CUR_DUP_2)
This bit indicates the actual duplex setting of switch Port 2.
0: Full-Duplex
1: Half-Duplex
Port 2 Current Receive Flow Control Enable (CUR_RX_FC_2)
This bit indicates the actual receive flow setting of switch Port 2.
0: Flow control receive is currently disabled
1: Flow control receive is currently enabled
Port 2 Current Transmit Flow Control Enable (CUR_TX_FC_2)
This bit indicates the actual transmit flow setting of switch Port 2.
0: Flow control transmit is currently disabled
1: Flow control transmit is currently enabled
Port 2 Full-Duplex Receive Flow Control Enable (RX_FC_2)
When the MANUAL_FC_2 bit is set, or Auto-Negotiation is disabled, this bit
enables/disables the detection of full-duplex Pause packets on switch Port 2.
0: Disable flow control receive
1: Enable flow control receive
Port 2 Full-Duplex Transmit Flow Control Enable (TX_FC_2)
When the MANUAL_FC_2 bit is set, or Auto-Negotiation is disabled, this bit
enables/disables full-duplex Pause packets to be generated on switch Port
2.
0: Disable flow control transmit
1: Enable flow control transmit
Port 2 Manual Flow Control Register (MANUAL_FC_2)
This read/write register allows for the manual configuration of the switch Port 2 flow control. This
register also provides read back of the currently enabled flow control settings, whether set manually
or Auto-Negotiated. Refer to
information.
Note: The flow control values in the PHY_AN_ADV_2 register (see
within the PHY are not affected by the values of this register.
