MII only - Receive Clock.
Accepts the following frequencies:
Collision Detection. This signal is
independent of M3_TXCLK and
M3_RXCLK, and is asserted when a
collision is detected on an attempted
transmission. It is active high, and only
specified for half-duplex operation.
Receive Data. Clocked on rising edge of
M3_RXCLK.
Receive Data Valid. Active high. This signal
is clocked on the rising edge of M3_RXCLK.
It is asserted when valid data is on the
M3_RXD bus.
Receive Error. Active high signal indicating
an error has been detected. Normally valid
when M3_RXDV is asserted. Can be used
in conjunction with M3_RXD when
M3_RXDV signal is de-asserted to indicate
a False Carrier.
Carrier Sense. This asynchronous signal is
asserted when either the transmission or
reception device is non-idle. It is active
high.
MII only - Transmit Clock
Accepts the following frequencies:
Transmit Data. Clocked on rising edge of
M3_TXCLK.
Transmit Enable. Asserted when the MAC
has data to transmit, synchronously to
M3_TXCLK with the first pre-amble of the
packet to be sent. Remains asserted until
the end of the packet transmission. Active
high.
Transmit Error. Transmitted synchronously
with respect to M3_TXCLK, and active high.
When asserted (with M3_TXEN also
asserted) the ZL50110/11/14 will transmit a
non-valid symbol, somewhere in the
transmitted frame.
