Table 2. MII
SW Signals
The MII-P5 interface operates in PHY mode only, while the MII-SW interface operates in either MAC mode or PHY mode
for KSZ8995MA. The MII-SW interface operates in PHY mode only for KSZ8995FQ. These interfaces are nibble-wide
data interfaces and therefore run at 1/4 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 MII-SW interface for PHY mode operation and the signal MTXER is
not provided on the MII-SW 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 KS8995MA/FQ has an
MRXER pin, it should be tied low. For MAC mode operation, if the device interfacing with the KS8995MA has an MTXER
pin, it should be tied low.
