ERXD0 is the Ethernet input data transferred from the PHY to the
media-access controller when ERxDV is asserted. This signal is used
for 10-Mbps Ethernet data. This signal is also used for MII mode
Ethernet data in conjunction with ERXD[3:1].
When asserted, indicates that transmit or receive medium is not idle.
Applies to MII mode operation.
In Ethernet mode, these pins contain the serial output Ethernet data
and are valid only during assertion of ETXEN in MII mode.
In Ethernet mode, when ETXER is asserted for one or more clock
cycles while ETXEN is also asserted, the PHY sends one or more
illegal symbols. ETXER has no effect at 10 Mbps or when ETXEN is
negated. Applies to MII mode operation.
In Ethernet mode, these pins contain the Ethernet input data
transferred from the PHY to the Media Access Controller when
ERXDV is asserted in MII mode operation.
In Ethernet mode, ERXER—when asserted with ERXDV—indicates
that the PHY has detected an error in the current frame. When
ERXDV is not asserted ERXER has no effect. Applies to MII mode
operation.

eTPU channels (TPUCH[31:16]) are available to the user. If negated,
the various Ethernet signals are available. Unexpected results will
occur if the signal state of eTPU/EthENB is changed after reset.
