Port 0(External MII) Full-Duplex Flow Control
Enable Strap: Configures the default of the
TX_FC_MII and RX_FC_MII bits in the Port
0(External MII) Manual Flow Control Register
(MANUAL_FC_MII). When latched low, flow control
is disabled on RX/TX. When latched high, flow
control is enabled on RX/TX. See Note 3.9.
Port 0(External MII) Manual Flow Control Enable
Strap: Configures the default value of the
MANUAL_FC_MII bit in the Port 0(External MII)
Manual Flow Control Register (MANUAL_FC_MII).
When latched low, flow control is determined by
Virtual Auto-Negotiation. When latched high, flow
control is determined by TX_FC_MII and
RX_FC_MII bits in the Port 0(External MII) Manual
Flow Control Register (MANUAL_FC_MII). See
Note 3.9, and Note 3.10.
Serial Management Mode Strap: Configures the
serial management mode.
00 = Unmanaged mode
01 = SMI Managed Mode
10 = I²C Managed Mode
11 = SPI Managed Mode
See Note 3.9.
MII Mode Strap: Configures the mode of the
external MII port.
0 = MAC Mode
1 = PHY Mode
See Note 3.9.
PHY Address Strap: Configures the default MII
management address values for the PHYs (Virtual,
Port 1, and Port 2) as detailed in Section 7.1.1,
"PHY Addressing," on page 84.
