MII MAC Mode: This pin is the transmit data 0 bit
from the switch to the external PHY.
MII PHY Mode: This pin is the receive data 0 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 the receive data 0 bit
from the switch to the external MAC. The output
driver is disabled when the
is set in the
(VPHY_BASIC_CTRL).
This strap configures the mode for Port 0. See
Note
The P0_MODE[2:0] configuration strap encoding is
as follows:
000 = MII MAC mode
001 = MII PHY mode
010 = MII PHY mode 200 Mbps 12 ma clock output
011 = MII PHY mode 200 Mbps 16 ma clock output
100 = RMII PHY mode clock is 12 ma output
101 = RMII PHY mode clock is 16 ma output
110 = RMII PHY mode clock is input
111 = RESERVED
MII MAC Mode: This pin is the TX_EN signal to the
external PHY and indicates valid data on
P0_OUTD[3:0].
MII PHY Mode: This pin is the RX_DV signal to the
external MAC. The output driver is disabled when
