device’s third MAC. The interface contains two distinct groups of signals: one for transmission and the other for
reception. The following table describes the signals used in the MII interface.

The MII interface operates in either PHY mode or MAC mode. The interface is a nibble wide data interface, and
therefore runs at the network bit rate (not encoded). Additional signals on the transmit side indicate when data is
valid or when an error occurs during transmission. Likewise, the receive side has indicators that convey when the
data is valid and without physical layer errors. For half duplex operation, there is a signal that indicates a collision has
occurred during transmission.
Note that the signal MRXER is not provided on the interface for PHY mode operation and the signal MTXER is not
provided on the interface for MAC mode operation. Normally, MRXER would indicate a receive error coming from the
physical layer device.
MTXER would indicate a transmit error from the MAC device.
These signals are not
appropriate for this configuration. For PHY mode operation, if the device interfacing with the KS8993F has an MRXER
pin, it should be tied low. For MAC mode operation, if the device interfacing with the KS8993F has an MTXER pin, it
should be tied low.
2.6
SNI (7-wire) Interface Operation
The SNI (Serial Network Interface) or 7-wire is compatible with some controllers used for network layer protocol
processing. In SNI mode, the KS8993F acts like a PHY and the external controller functions as the MAC. The
KS8993F can interface directly with external controllers using the 7-wire interface. These signals are divided into two
groups, one for transmission and the other for reception. The signals involved are described in the following table.
