Receive Data:
Each bus carries eight data bits [7:0] of
the received data stream.
RGMII Mode: When a port ID is
configured in copper mode and the
RGMII interface is selected, only bits
RXD[3:0]_n are used to receive data.
Fiber Mode: The following signals
have multiplexed functions when a port
is configured in fiber mode:
RXD4_n: MOD_DEF_0:3
RXD5_n: TX_FAULT_0:3
RXD6_n: RX_LOS_0:3
