Note that the signal MRXER is not provided on the MII interface for the KS8999 for PHY mode operation and MTXER
is not represented for MAC mode. Normally this would indicate a receive / transmit error coming from the physical
layer /MAC device, but is not appropriate for this configuration. If the connecting device has a MRXER pin, this
should be tied low on the other device for reverse or if it has a MTXER pin in the forward mode it should also be tied
low on the other device.
The following explains the KS8999 in PHY mode and MAC mode of operation:
