Description
50-MHz reference clocks. These pins input reference signals for
transmission/reception timings in RMII mode.
Indicate that there are carrier detection signals and valid
receive data on RMII_RXD1 and RMII_RXD0 in RMII mode.
2-bit transmit data in RMII mode
2-bit receive data in RMII mode
Output pins for data transmit enable signals in RMII mode
Indicate an error has occurred during reception of data in RMII
mode.
Carrier detection/data reception enable pins
Indicate that there are valid receive data on ET_ERXD3 to
ET_ERXD0.
General-purpose external output pins
Input link status from the PHY-LSI.
4 bits of MII transmit data
4 bits of MII receive data
Transmit enable pins. Function as signals indicating that
transmit data is ready on ET_ETXD3 to ET_ETXD0.
Transmit error pins. Function as signals notifying the PHY-LSI of
an error during transmission.
Receive error pins. Function as signals to recognize an error
during reception.
Transmit clock pins. These pins input reference signals for
output timings from ET_TX_EN, ET_ETXD3 to ET_ETXD0, and
ET_TX_ER.
Receive clock pins. These pins input reference signals for input
timings to ET_RX_DV, ET_ERXD3 to ET_ERXD0, and
ET_RX_ER.
Input collision detection signals.
Receive Magic packets.
Output reference clock signals for information transfer via
ET_MDIO.
Input or output bidirectional signals for exchange of
management information between this MCU and the PHY-LSI.
