Connects to the PCMCIA I/O write strobe pin.
Connects to the PCMCIA I/O read strobe pin.
Connects to the PCMCIA memory write strobe.
In little endian mode, this signal indicates 16-bit bus width of
PCMCIA. In big endian mode, fix this pin low.
Collision detect pin
Indicates that transmit data is on pins MII_TXD3 to
MII_TXD0.
Timing reference input for the TX_EN, TX_ER, and
MII_TXD3 to MII_TXD0 pins
4-bit receive data pins
Indicates that valid receive data is on pins MII_RXD3 to
