MII MAC Mode: This pin is the receive data 2 bit
from the external PHY to the switch.
MII PHY Mode: This pin is transmit data 2 bit from
the external MAC to the switch. The pull-down and
input buffer are disabled when the Isolate
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
RMII 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
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
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
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
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
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
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
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
MII MAC Mode: This pin is the RX_DV signal from
the external PHY and indicates valid data on
P0_IND[3:0] and P0_INER.
MII PHY Mode: This pin is the TX_EN signal from
the external MAC and indicates valid data on
P0_IND[3:0] and P0_INER. The pull-down and
input buffer are disabled when the Isolate
(VPHY_ISO) bit is set in the Virtual PHY Basic
Control Register (VPHY_BASIC_CTRL).
RMII PHY Mode: This pin is the TX_EN signal from
the external MAC and indicates valid data on
P0_IND[1:0]. The pull-down and input buffer are
disabled when the Isolate (VPHY_ISO) bit is set in
the Virtual PHY Basic Control Register
(VPHY_BASIC_CTRL).
