MII MAC Mode: This pin is the receive data 3 bit
from the external PHY to the switch.
MII PHY Mode: This pin is the transmit data 3 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
RMII PHY Mode: This pin is not used.
Internal PHY Mode: This pin is not used.
MII MAC Mode: This pin is the receive data 2 bit
from the external PHY to the switch.
MII PHY Mode: This pin is the transmit data 2 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
RMII PHY Mode: This pin is not used.
Internal PHY Mode: This pin is not used.
MII MAC Mode: This pin is the receive data 1 bit
from the external PHY to the switch.
MII PHY Mode: This pin is the transmit data 1 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
RMII PHY Mode: This pin is the transmit data 1 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
Internal PHY Mode: This pin is not used.
MII MAC Mode: This pin is the receive data 0 bit
from the external PHY to the switch.
MII PHY Mode: This pin is the transmit data 0 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
RMII PHY Mode: This pin is the transmit data 0 bit
from the external MAC to the switch. The pull-down
and input buffer are disabled when the Isolate bit is
set in the Port 1 MII Basic Control Register
(P1_MII_BASIC_CONTROL).
Internal PHY Mode: This pin is not used.
