RMII mode
Example code:
ENET_RCR_CRCFWD_MASK | ENET_RCR_RMII_MODE_MASK;
12.5.1.1 Hardware implementation
The following two figures show the connection needed from the MAC-NET pins to any
generic Ethernet PHYs in RMII mode.
The connection from the RMII0_CRS_DV is dependent on the PHY implementation. In
the first figure, the RMII0_CRS_DV signal is connected to the RXDV/CRSDV pin.
The RMII0_RCR_DV is connected to the CRS/CRSDV. Hardware designs need to be
taken into consideration depending on the specific PHY used.
