Note:
1.
MAC/PHY mode in RMII is difference with MAC/PHY mode in MII, there is no strap pin and register configuration request in RMII, just follow
the signals connection in the table.

SNI Interface Operation
The serial network interface (SNI) is compatible with some controllers used for network layer protocol processing.
This interface can be directly connected to these types of devices. The signals are divided into two groups, one for
transmission and the other for reception. The signals involved are described in Table below.

Table 6. SNI Signals
This interface is a bit-wide data interface, so it runs at the network bit rate (not encoded). An additional signal on the
transmit side indicates when data is valid. Likewise, the receive side has an indicator that shows when the data is
valid.
For half-duplex operation there is a signal that indicates a collision has occurred during transmission.
