The SNI interface is a bit wide data interface and therefore runs at the network bit rate (not encoded). An additional
signal on the transmit side indicates when data is valid. Similarly, the receive side has an indicator that conveys when
the data is valid.
For half duplex operation, the KS8993F SCOL signal is used to indicate that a collision has occurred during
transmission.

MII Management Interface (MIIM)
The KS8993F supports the IEEE 802.3 MII Management Interface, also known as the Management Data Input /
Output (MDIO) Interface. This interface allows upper-layer devices to monitor and control the states of the KS8993F.
An external device with MDC/MDIO capability can be used to read the PHY status or configure the PHY settings.
Further details on the MIIM interface can be found in section 22.2.4.5 of the IEEE 802.3 specification.
The MIIM interface consists of the following:
A physical connection that incorporates the data line (MDIO) and the clock line (MDC).
A specific protocol that operates across the aforementioned physical connection that allows an external
controller to communicate with the KS8993F device.
Access to a set of six 16-bits registers, consisting of standard MIIM registers [0:5].
The following table depicts the MII Management Interface frame format.

For the KS8993F, MIIM register access is selected when bit 2 of the PHY address is set to ‘0’. PHY address bits [4:3]
are not defined for MIIM register access, and hence can be set to either 0’s or 1’s in read/write operation.
