ETHERNET MAC (EMAC) [MII/RMII/GMII]
If the Ethernet MAC (EMAC) and MDIO are enabled (AEA12 driven low [UTOPIA_EN = 0]), there are two additional configuration pins —
the MAC_SEL[1:0] (AEA[10:9] pins) that select one of the four interface modes (MII, RMII, GMII, or RGMII) for the EMAC/MDIO interface.
For more detailed information on the EMAC configuration pins, see
Section 3

the UTOPIA peripheral is disabled (UTOPIA_EN [AEA12 pin] = 0), this pin is

pin is EMAC carrier sense (MCRS) (
I
) for MII [default] or GMII, or EMAC carrier
sense/receive data valid (RMCRSDV) (

UTOPIA receive Start-of-Cell signal (
I
) or when the UTOPIA peripheral is

disabled (UTOPIA_EN [AEA12 pin] = 0), this pin is EMAC receive error

Controller to indicate to the UTOPIA Slave to sample the Receive Data Bus
(URDATA[7:0]) and URSOC signal in the next clock cycle or thereafter.
