General Purpose Input/ Output Pin 1. This pin is default as input pin after
power-on reset. This pin is also for Default WOL Ready Mode setting;
please refer to section
2.3
Settings.
General Purpose Input/ Output Pin 0 or PME (Power Management Event).
This pin is default as input pin after power-on reset. GPIO_0 also can be
defined as PME output to indicate wake up event detected. Please refer to
section
2.3
Settings.
UART_RX or SPI_MISO. This is a multi-function pin determined by
EEPROM Flag [1] setting. Please refer to section
2.3
Settings.
UART_TX or SPI_MOSI. This is a multi-function pin determined by
EEPROM Flag [1] setting. Please refer to section
2.3
Settings.
I2C_SDA or SPI_SS. This is a multi-function pin determined by
EEPROM Flag [1] setting. Please refer to section
2.3
Settings.
I2C_SCLK or SPI_SCLK. This is a multi-function pin determined by
EEPROM Flag [1] setting. Please refer to section
2.3
Settings.
USB Speed indicator: When USB bus is in Full speed, this pin drives high
continuously. When USB bus is in High speed, this pin drives low
continuously. This pin drives high and low in turn (blinking) to indicate
TX data transfer going on whenever the host controller sends bulk out data
transfer.
Test pin. For normal operation, user should connect to ground.

External Media Interface: MAC Mode with MII Interface
17
Receive Clock.
RXCLK is received from PHY to provide timing reference
for the transfer of RXD [3:0] and RXDV signals on receive direction of
MII interface.
18
Receive Data Valid.
RXDV is asserted high when valid data is present on
RXD [3:0]. It is driven synchronously with respect to RXCLK by PHY.

Carrier Sense. CRS is asserted high asynchronously by the PHY when
either transmit or receive medium is non-idle.
