Receive Error. Active high signal indicating
an error has been detected. Normally valid
when M2_RXDV is asserted. Can be used
in conjunction with M2_RXD when
M2_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
M2_TXCLK.
Transmit Enable. Asserted when the MAC
has data to transmit, synchronously to
M2_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 M2_TXCLK, and active high.
When asserted (with M2_TXEN also
asserted) the ZL50110/11/14 will transmit a
non-valid symbol, somewhere in the
transmitted frame.
LED drive for MAC 3 to indicate port is
linked up.
Logic 0 output = LED on
Logic 1 output = LED off
