Please see the pins [47, 48] description for detail configuration for the MAC mode and PHY mode of the port 4 MAC4
SW4-MII, the default is SW4-MII with PHY mode. Please see the strap pin P2LED0 and the register 223 bit 6 for the MAC
mode and PHY mode of the port 3 MAC3 SW3-MII, the default is SW3-MII with PHY mode also.

Table 3. Switch MAC 3 SW3-MII and MAC 4 SW4-MII Signals
The switch MII interface operates in either MAC mode or PHY mode for KSZ8864RMN. These interfaces are nibble-wide
data interfaces and therefore run at one-quarter 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 SWx-MII interface and the signal MTXER is not provided on the SWx-
MII interface for both PHY and 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 KSZ8864RMN has an MRXER pin, it should
be tied low. For MAC mode operation, if the device interfacing with the KSZ8864RMN has an MTXER pin, it should be
tied low.
