MII Receive Data:
In MAC mode, this signal is input from an
external PHY.
In PHY mode, this signal is output to an external
MAC. This signal is always driven low when in
PHY mode. See
In MAC mode, this signal is output to an external
PHY and indicates an invalid symbol is to be
transmitted. This signal is always driven low
when in MAC mode. See
In PHY mode, this signal is input from an external
MAC and indicates the current packet should be
aborted.
In MAC mode, this signal is input from an
external PHY.
In PHY mode, this signal is output to an external
MAC. See
In MAC mode, this signal is input from an
external PHY.
In PHY mode, this signal is output to an external
MAC. See
In MAC mode, this is the transmitter clock input
from an external PHY.
In PHY mode, this is the transmitter clock output
to an external MAC. See
In MAC mode, this is the data from an external
PHY to the LAN9313/LAN9313i switch.
In PHY mode, this is the data from the
LAN9313/LAN9313i switch to an external MAC.
