detection
Carrier detection pin. For a
connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1/0
collision
detection
Collision detection pin. For a
connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1 transmit
data
4-bit transmit data pins. For a
connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC0 transmit
data
4-bit transmit data pins. For a
connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1/0
transmit enable
These pins indicate that transmit
data is ready on ETXD13 to
ETXD10 and ETXD03 to ETXD00.
For a connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1/0
transmit clock
Timing reference pins (clock) for

ETXD10 and ETXD03 to ETXD00.
For a connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1/0
transmit error
These pins notify an error during
transmission to the PHY-LSI. For
a connection example, refer to
section 18, Ethernet Controller
(EtherC).
MAC1/0 receive These pins notify an error during
error
data reception. For a connection
example, refer to section 18,
Ethernet Controller (EtherC).
