Description
MII transmit clock
It is an input signal when MII works at MAC mode. It should be
connected to MII RXCLK of an external PHY.
MII transmit data
They are input signals when MII works at MAC mode. They are
sampled at the rising edge of TXCLK. They should be connected
to MII RXD of an external PHY.
IPH2 MII transmit enable
It is an input signal when MII works at MAC mode. It is used to
frame TXD [3:0]. It is sampled at the rising edge of TXCLK. It
should be connected to MII RXDV of an external PHY.
IPH1/
O
It is an output signal when MII works at MAC mode. It is used to
frame RXD [3:0]. It is sent out at the falling edge of RXCLK. It
should be connected to MII TXEN of an external PHY.

IPH2 MII receive clock
It is an input signal when MII works at MAC mode. It should be
connected to MII TXCLK of an external PHY.
This pin should be left open whenf MII/RMII is disabled.
