MII MAC Mode: This pin is the RX_ER signal from
the external PHY and indicates a receive error in
the packet.
MII PHY Mode: This pin is the TX_ER signal from
the external MAC and indicates that the current
packet should be aborted. The pull-down and input
buffer are disabled when the
bit is set in the
(VPHY_BASIC_CTRL).
RMII PHY Mode: This pin is not used.
MII MAC Mode: This pin is an input and is used as
the reference clock for the P0_IND[3:0], P0_INER,
and P0_INDV pins. It is connected to the receive
clock of the external PHY.
MII PHY Mode: This pin is an output and is used
as the reference clock for the P0_IND[3:0],
P0_INER, and P0_INDV pins. It is connected to the
transmit clock of the external MAC. The output
driver is disabled when the
is set in the
(VPHY_BASIC_CTRL). When operating at
200MBps, the choice of drive strength is based on
the setting of the
in the
(VPHY_SPECIAL_CONTROL_STATUS). A low
selects a 12 mA drive, while a high selects a 16 mA
drive. A series terminating resistor is recommended
for the best PCB signal integrity.
RMII PHY Mode: This pin is not used.
MII MAC Mode: This pin is the transmit data 3 bit
from the switch to the external PHY.
MII PHY Mode: This pin is the receive data 3 bit
from the switch to the external MAC. The output
driver is disabled when the
is set in the
(VPHY_BASIC_CTRL).
RMII PHY Mode: This pin is not used
This strap selects the default of the duplex polarity
strap for Port 0 MII (duplex_pol_strap_0). See
Note
If the strap is value is 0, a 0 on P0_DUPLEX
means full duplex while a 1 means half duplex. If
the strap value is 1, a 1 on P0_DUPLEX means full
duplex, while a 0 means half duplex.
