Abbreviation
ERXDV
Asserted to indicate that the PHY has
valid nibbles present on the MII.
ERXD0
Ethernet input data transferred from
the PHY to the media access
controller (when ERXDV is asserted).
ECRS
Asserted to indicate that the transmit
or receive medium is not idle.
ETXD[3:1]
Contain the serial output Ethernet
data.
ETXER
Asserted (for one or more E_TXCLKs
while ETXEN is also asserted) to
cause the PHY to send one or more
illegal symbols.
ERXD[3:1]
Contain the Ethernet input data
transferred from the PHY to the media
access controller (when ERXDV is
asserted in MII mode).
ERXER
Indicates (when asserted with
ERXDV) that the PHY has detected
an error in the current frame.
Queued Serial Peripheral Interface (QSPI) Signals
QSPI_DOUT
Provides serial data from the QSPI.
QSPI_DIN
Provides serial data to the QSPI.
QSPI_CLK
Provides the serial clock from the
QSPI.
QSPI_CS[3:0]
Provide QSPI peripheral chip selects.
